Auto Fuel Savers
RunningCarWithWater.com, claims they can double your auto gas mileage and reduce fuel emissions by installing one of their devices that supposedly extracts a hydrogen compound that mixes with your gas to improve engine efficiency. They claim to be EPA approved. Is this true?
I assume you meant http://www.runacaronwater.com/. RunningCarWithWater.com doesn't appear to be a valid URL. I haven't been able to find a definitive answer to your question. I've forwarded it to one of our technical assistance engineers, who may be able to give you an answer. Meanwhile, you may want to take a look at the following: Running a car on waterhttp://www.mitra.biz/blog/archives/2007/04/running_a_car_o.html
Running Cars on Hydrogen Made from Starch Response from ISTC engineer: I looked briefly at the web page runacaronwater, and I've seen other "easy" bolt-on systems that claim similar improvements. The claims are attractive, especially to the conspiracy theorists in many of us. I'm both curious and skeptical, leaning very much towards skeptical/doubtful. I've never seen more than performance claims via the internet. I'd be very happy to see an actual system in place or meet someone who's done it. Maybe you can find enough interested people to chip in the money to conduct a test. If you ever do, I hope you'll share your results. Comments (0) | Was this answer helpful to you? | Permalink
Start up grants for a green business
We are looking for information about grants for start-up costs for a business in the green industry. We are based in Indiana. The company intents to provide services that allow a homeowner/business owner to retro fit their home/building with energy efficient products. That would include tripolymer foam insulation, high efficiency heating and air (including geo thermal), Solar panels, tankless water heaters, reverse osmosis systems/ water filters, and high efficiency appliances.
1 of 1 people found this answer helpful. The U.S. Department of Energy has some funding opportunities available at http://www1.eere.energy.gov/financing/. I don't know if they fund the kind of business you're interested in starting though. A better bet would be the Indiana Office of Energy and Defense Development. They're on the web at http://www.in.gov/energy/ENERGY/energydiv.html. There is contact information for the office at http://www.eere.energy.gov/state_energy_program/seo_contacts_by_state.cfm/state=IN. U.S. EPA has a web site with green building funding opportunities. See http://www.epa.gov/greenbuilding/tools/funding.htm. You may also want to check out the Database of State Incentives for Renewable Energy. Indiana's information is at http://www.dsireusa.org/library/includes/map2.cfm?CurrentPageID=1&State=IN&RE=1&EE=1. Finally, you may want to contact the Indiana Small Business Development Center (http://www.isbdc.org/). They are a state based organization offering a wealth of free and low cost information, management counseling, and educational services designed to support Indiana small business owners and potential entrepreneurs. The University of Illinois at Urbana-Champaign also has some good information on start-up financing for small business. See http://smartenergy.arch.uiuc.edu/html/info%5Floan.html. Although many of the resources are specific to Illinois, there are links to federal programs as well. I hope this is enough information to get you started. If you need further assistance, please let me know. Comments (0) | Was this answer helpful to you? | Permalink
Paper use
I have a question regarding using paper fast food napkins, paper towels and toilet paper to help save the world in doing our part for conservation. The other day on the Oprah show, a guest suggested we should cut down our use of paper napkins to save a bunch of trees. I think we should use less paper towels too. And, I wondered if the use of single ply toilet paper would also help save the trees as well as saving us trouble with our potty drains not just in homes but in homes where the drainage system isn't that great. What do you think? Should we all buy single ply? Shouldn't we use linen napkins more. Any additional suggestions for conservation with regard to paper?
As with most consumer choices, there are trade-offs. For example, if you use cloth napkins instead of paper, you're still going to effect the environment every time you wash them, especially if you're not using eco-friendly laundry detergent. However, if you use paper products made from post-consumer recycled content, you'll also minimize your environmental footprint. For an excellent discussion these issues, take a look at The Consumer's Guide to Effective Environmental Choices (http://www.worldcat.org/oclc/39335766). Although it was published in 1999, it's still the best book I've seen for helping consumers make choices that really will have an environmental impact. That being said, there are ways that we can all reduce our use of paper (although I'm personally not willing to skimp on the toilet paper). Some resources include:
Simple Ways to Reduce Office Paper Waste and Make Better Use of the Paper You Need
A Shopper's Guide to Home Tissue Products
Action Guide to Greener Paper

Electronics Disposal
I have a number of electronic items such as tuners, amplifiers, speakers,
etc. that I wish to dispose of. Can you direct me to a recycling
facility for such equipment? I live in Rockton, IL 61072, just north of Rockford.
1 of 2 people found this answer helpful. If the equipment still works (or even if it doesn't), you could offer it through Rockford's Freecycle group. See http://www.freecycle.org/group/US/Illinois/Rockford for more information. Best Buy's recycling program is one option (http://www.bestbuy.com/recycling). They take audio components, but I don't know if they take them at any time or if you have to wait for a specific event. Call your local store to find out. The Illinois Department of Commerce and Economic Opportunity has a directory of Illinois electronics recyclers on the web at http://www.illinoisbiz.biz/NR/rdonlyres/3622F4E9-0FC6-4F02-9820-231C99D2A88D/0 FY_08_IllinoisDirectoryofElectronicEquipmentandComputerRecyclers.pdf.

What is the meaning of biodegradable/biocomposites contained in plastic?
May I know what is are the definitions of and difference between biodegradable and biocomposites?
1 of 1 people found this answer helpful. Here are the definitions from Wikipedia:
Biocomposites: A biocomposite is a material formed by a matrix (resin) and a reinforcement of natural fibers (usually derived from plants or cellulose). With wide-ranging uses from environment-friendly biodegradable composites to biomedical composites for drug/gene delivery, tissue engineering applications and cosmetic orthodontics. They often mimic the structures of the living materials involved in the process in addition to the strengthening properties of the matrix that was used but still providing biocompatibility, e.g in creating scaffolds in bone tissue engineering.
Biodegradable: Biodegradation is the process by which organic substances are broken down by living organisms. The term is often used in relation to ecology, waste management, environmental remediation (bioremediation) and to plastic materials, due to their long life span. Organic material can be degraded aerobically, with oxygen, or anaerobically, without oxygen. Comments (0) | Was this answer helpful to you? | Permalink

asbestos
Is there a list of art supplies that contained asbestos?
I have been unable to find such a list. According to "Are Art Supplies Toxic?" (http://www.coopamerica.org/pubs/realmoney/articles/toxicart.cfm): "In 2000, ACMI's [Art and Creative Materials Institute] safety protocols came under fire when the Seattle Post-Intelligencer [http://seattlepi.nwsource.com/national/cray23.shtml] broke the news that carcinogenic asbestos had been found in Crayola, Prang, and Rose Art crayons, all of which bear the nontoxic AP label. While asbestos was not an actual ingredient in any of the three brands, it is a common contaminant of talc, which had long been used as a strengthener in crayons. (Later that year, all three manufacturers agreed to stop using talc in crayons.) Fanning says ACMI responded immediately, conducting its own testing, and the CPSC tested the three brands as well. None found asbestos. "What we and the CPSC did find were talc fibers and cleavage fragments, which are too short to be asbestos but are often misinterpreted by some labs as asbestos," says Fanning. "Had we found asbestiform contaminants at a hazardous level, we would have taken our AP labels off immediately, and the manufacturers would have had to take their crayons off the market until they complied with our standards again." For further information, see:

Environmental Opportunity Assessments of Company Cafeterias
We would like to hire external consultants to come in a do a detailed review of our current cafeteria operations, to evaluate opportunities to reduce energy, water and waste usage, to increase recycling rates, and to evaluate procurement opportunities. We would also like total cost accounting to be considered when recommendations are made. We want to bring people in who have expertise in the food service industry, as opposed to environmental consultants who are typically process engineers and have much experience in manufacturing settings. Any suggestions as to organizations I could contact to locate these subject matter experts?
I did a Google search on "food service" consultant and found the Foodservice Consultants Society International (http://www.fcsi.org/). I searched their membership directory (http://www.fcsi.org/directory.taf) for "Energy & Environment" and Illinois and found Harry Schildkraut of S3 Consulting, located in Hawthorn Woods, IL.

Biodiesel tax incentives
I have heard about a $1/gallon government incentive for biodiesel. I would like some information about who provides the incentive and who gets it.
This incentive is also known as the Biodiesel and Ethanol (VEETC) Tax Credit. According to the U.S. Department of Energy, the American Jobs Creation Act of 2004 (Public Law 108-357) created tax incentives for biodiesel fuels and extended the tax credit for fuel ethanol. The biodiesel credit is available to blenders/retailers beginning in January 2005. It also established the Volumetric Ethanol Excise Tax Credit (VEETC), which provides ethanol blenders/retailers with $.51 per pure gallon of ethanol blended or $.0051 per percentage point of ethanol blended (i.e., E10 is eligible for $.051/gal; E85 is eligible for $.4335/gal). The incentive is available until 2010. Section 1344 of the Energy Policy Act of 2005 extended the tax credit for biodiesel producers through 2008. The credits are $.51 per gallon of ethanol at 190 proof or greater, $1.00 per gallon of agri-biodiesel, and $.50 per gallon of waste-grease biodiesel. If the fuel is used in a mixture, the credit amounts to $.0051 per percentage point ethanol or $.01 per percentage point of agri-biodiesel used or $.0050 per percentage point of waste-grease biodiesel (i.e. E100 is eligible for $.51 per gallon) (Source: http://www.eere.energy.gov/afdc/progs/view_ind_fed.cgi?afdc/319/0) For more details on this program and other incentives for using alternative fuel sources, see:

Long term effects of spraying
I am trying to get information on the long term effects of spraying Budd
Lake in Harrison for the invasive weed infestation. Do have or know of any sources?
I assume you mean Budd Lake in Michigan. Without knowing what they're spraying, I can't give you specific information. If you do know what is being sprayed, you should be able to find information for that specific chemical in the Agency for Toxic Substances and Disease Registry's ToxFAQs. See http://www.atsdr.cdc.gov/toxfaq.html. If you don't know what is being sprayed, I suggest contacting whoever is doing the spraying to find out. If you don't know who that is, then try contacting the Inland Lakes and Streams program at the Michigan Department of Environmental Quality (e-mail: hassj@michigan.gov or phone: (517) 241-3139).

Great Lakes Food Processing Industry Facilities
The Multimedia Environmental Compiance Guide for Food Processors (US EPA, 1999) uses a 1994 Department of Commerce map (Table 1-1) that shows the distribution of food processing (SIC 20) facilities throughout the US.

Water standards and informatin about chemicals to clean heat exchangers
I am a metallurgist. My client wants me to recommend a new material for heat exchanger tubing used at a waste water plant because of corrosion problems. He has given me tables of water data. I don't know how to interpret them. I need to find out what the "worst" stuff is. Please provide me with water information. Parameters he has given me are: Alkalinity, Ammonia, Fecal Coli.,CBOD5, KN, soluble, Nitrate-N, Total suspension, Volatile suspension, Sulfate.. and more (usually g/ml). He also wants me to recommend any testing he might need to do for other water parameters. I don't think typical things like Fe, Ca, are an issue.
You should be able to find the answers to your questions in Water Treatment: Principles and Design (New York : Wiley, 2005). The ISBN is 0-471-11018-3. You can view the table of contents at http://www.wiley.com/WileyCDA/WileyTitle/productCd-0471110183.html. It has fairly detailed information on contaminants normally encountered in wastewater treatment plants and should have enough information to help you decipher the data your client gave you and make some recommendations.

Ethanol plants and the environment
Do you have any information about the environmental impact of ethanol plants, particularly their water use?
You probably have some of this general information, but just in case, you might want to look at:
Wikipedia: Ethanol fuel As for water use, it depends on the size of the plant. According to Environmental Issues and Ethanol Production: Water Issues (http://econet.sk.ca/issues/ethanol/envissues.html): The quantity of water needed depends on the design of the production plant and whether or not it is built in conjunction with a feedlot. Modern technology and design can substantially reduce the amount of fresh water needed by a stand-alone ethanol plant. There are "zero discharge" plants in operation that recycle virtually all of the water used in production, limiting the need for large supplies. The Illinois Environmental Protection Agency and Illinois Department of Commerce and Economic Opportunity have just released a new guidebook called Building an Ethanol Plant in Illinois: A Guide to Permit Requirements, Funding Opportunities, and Other Considerations. It's available on the web at http://www.epa.state.il.us/agriculture/building-an-ethanol-plant.pdf. See also a press release about a related workshop held in January 2006 (http://www.ilcorn.org/news/html/1-25-06.html). It includes contact information that might be helpful. You also might want to take a look at An Ethanol Production Guidebook for the Northeast States (http://www.nrbp.org/pdfs/pub26.pdf). It includes information about environmental considerations. For more information, you may also want to contact the National Corn to Ethanol Research Center (http://www.ethanolresearch.com/), located on the SIU-Edwardsville campus.

P2 for funeral homes/mortuaries/the funeral industry
Have any of you ever worked on tech assistance for funeral homes/mortuaries? I found one 1995 study on Formaldehyde Use Reduction, do you know of any other good ones out there?
There was a discussion on P2Tech about four years ago about environmental issues associated with crematoria, which are slightly different than funeral homes, but certainly related. At the time, I did a search for one of our staff people on the issue too. Here's what I found: A search of the P2Tech archives (http://www.great-lakes.net/lists/p2tech/) turned up the following (in response to a message originally posted by John Marlin):
· Subject: Re: crematoria The problem that I understand is that the fillings in the deceased teeth are heated causing some mercury to be volatilized. Crematoria typically do not have air pollution control devices. I understand that in California the morticians have to pull the teeth prior to the baking. This is pollution prevention at work. I do not know what other types of emissions are released from the naked point source (often in close proximity to a neighborhood). Sort of conjures up scenes from ghostbusters!
· Subject: RE: crematoria · From: John Calcagni · Date: Tue, 29 Dec 1998 16:34:25 -0500 · List-Name: P2Tech Follow up to my previous message: I spoke to Rick Copeland at EPA who headed up the effort on the medical waste incineration standards for air, regarding medical waste incinerators(MWI) and he indicated that the issues are not transferrable to crematoria. In fact, crematoria are specifically exempt from the MWI standards. MWI burn a lot of plastics and contaminated supplies which contribute substantial chlorine to the formation of HCl and possibly dioxins and heavy metals. These constituents pose the greater air risk. Tissue matter which is 96% water does not pose these kinds of problems. The EPA air program is looking into crematoria as part of other waste disposal such as combustion of chicken carcasses. He expects mercury from fillings being a problem unique to crematoria since it volatilizes at low combustion temperatures and is not easily removed. Ironically the chlorine levels in MWI result in the formation of HgCl2 which can be removed from the air more easily but ends up in the water. · Subject: Re: crematoria · From: "Kirsten Sinclair Rosselot" · Date: Tue, 29 Dec 1998 21:17:02 -0800 · List-Name: P2Tech According to the L&E document for dioxins and furans ("Locating and Estimating Air Emissions from Sources of Dioxins and Furans (Draft)," U.S. EPA, May 1996), crematories are a source of dioxin and furan emissions. Incomplete combustion, don't you know.... I've wondered if maybe it wasn't the materials burned with the bodies (clothing, containers, etc.) that caused the dioxin and furan emissions, or perhaps things like artificial hips made of plastic. Emissions could depend on factors such as body composition, too, I suspect. The quantities of dioxins and furans emitted are tiny -- on the order of ten to the minus 13 kilograms per pound of body. However, even tiny amounts of these compounds can be cause for concern. · Subject: Crematoria · From: Jeff Cantin · Date: Wed, 06 Jan 1999 13:51:10 -0500 · List-Name: P2Tech I also did some searching on the web and found the following sites: Environmental Effects Main Crematorium Concern http://www.gmnews.com/Atlanticville/News/2001/0802/Front_Page/008.html Dioxinlike Components in Incinerator Fly Ash: A Comparison between Chemical Analysis Data and Results from a Cell Culture Bioassay (article abstract) http://ehpnet1.niehs.nih.gov/docs/1997/105-12/till.html Inventory of Sources of Dioxin in the United States (see section 3.4 beginning on page 3-37 for information on crematoria.

ECOCEMETERY OFFERS NATURAL BURIAL IN WOODLAND PRESERVE Conventional burial in the United States bears a resemblance to toxic waste disposal. The Environmental Protection Agency has raised concerns about discharge of embalming fluids from funeral homes into septic and sewage systems. Caskets and vaults may contaminate soil and groundwater by leaching varnishes, preservatives, sealants and metals. Most cemeteries are kept verdant by regular applications of herbicides and pesticides and are "beautified" with turf and invasive exotic species. But in Westminster, South Carolina, Billy and Kimberly Campbell have founded Memorial Ecosystems, the first contemporary cemetery in the nation dedicated to ecosystem preservation while providing a lower-cost burial alternative. At the company's pilot "ecocemetery," unembalmed bodies are buried in biodegradable cardboard cremation boxes or simple pine coffins in a native woodland. Plots are sited close to the trail to avoid visitors' trampling the woodland vegetation. Where topsoil must be removed, it is replaced after burial. Grave markers are simple inscriptions on stones mostly found on the property. The Campbells will allow an average of 30 graves per acre, compared to 1,000 or more per acre in some contemporary cemeteries. While burial requirements differ from state to state, they are less constricting than one might expect. In South Carolina, for example, not even a box is legally required.

Water-based adhesives
We are studing about water base adhesive market situation. I read PPRC's water based adhesive technolgy review, released September 1998. Do you have any up data about the market situation or recommend some studies?
I did a literature search of Google, Compendex (Engineering Index), and the WMRC Library's in-house article database for studies completed since 2000. I've also forwarded your e-mail to PPRC in case they have anything to add. ht You may also want to take a look at the current issue of Adhesives & Sealants Industry. One of the featured articles is a 2006 industry outlook. (http://www.adhesivesmag.com/CDA/Archives/d2175fdd41bc8010VgnVCM100000f932a8c0____) You can also locate more information about the latest developments in adhesives by contacting one of the trade organizations that represent adhesive manufacturers. There is a list at http://www.glueit.com/trade-associations.html. Please note that we will not provide copies of articles from our database or Compendex. You should be able to obtain them through your local library's interlibrary loan service. Here are the search results: WEB SEARCH

P2 for maple syrup processors
Are there any markets for the water produced by separating it from maple tree sap using a reverse osmosis process? Also is there any P2 guidance info for maple syrup processors?
Answers to this question came from members of the P2Tech e-mail list: Response 1: Assuming the RO system is maintained well and no membrane leaks are allowed, the water generated is permeate - essentially deionized water. By its properties it should be drinkable, although given that it does not come from a potable source, it is unlikely a health department would allow it to be labeled or used as potable without testing. In terms of markets, there should be nothing present in the water that makes it more valuable than plain water. It can be used for irrigation, for cleaning, for toilets etc. It will not have a high value, so it is not the type of material that could be trucked very far to another user. A similar stream is condensate of whey (COW water) from cheese processing. It was originally a bi-product from multiple effect evaporators and now also comes as the permeate stream from RO processing of dilute whey. In cheese dairies it is commonly used for equipment cleaning, and vacuum pump seals. Another similar stream is RO reject water from further purifying potable water. It is city water with doubled or tripled dissolved salt content. It is fairly common that it is discharged directly to surface waters under an NPDES permit, with no treatment other than assuring that there is no residual chlorine present. This could be a last resort for maple syrup permeate, but it would be an unfortunate and wasteful disposition for very clean water. Response 2: Without an analysis of the water I am shooting in the dark. The RO water should be useful for wash water or make up water for boilers if low conductivity. It may need UV treatment for wash water to keep the health inspectors happy. It all depends also on the sugar content for wash water. It would also be a potential wash water for the RO system prior to maintenance. The process condensate from evaporation processes would likely be suitable for making low pressure steam with little additional chemical treatment. It should be soft and low conductivity to start with. The water and wash water from your process and floors would have sugars that could be beneficial to compost producers. The value would likely approach the trucking cost if the composter is nearby provided the sugar content was 2%. You may collect first hot rinse to help the sugar content. Maybe you could make a natural drink. Check out the nutrient content..."Bottled Maple Nutrient Drink." Response 3: That's a sticky problem you've got there.... I cannot recall the name of the firm but a few years back I spoke at a P2 workshop for food processors, conducted by SC Edison in ag regions of southern california. One of the other speakers was from a company that bought and processed all sorts of sugar-bearing aqueous waste streams, which they would then process into fermentable feedstocks and use to produce ethanol and/or citric acid. I apologize for not remembering the name of the firm -- I do recall that they were located in Orange County, CA -- but I mention it because it leads me to believe that the business model has probably been replicated in other regions. I tried a quick Google search to find similar firms but came up empty, but a call to your local cider mill or juice plant, inquiring about what they do with their off-spec product, might provide good leads. Hmmmm...what else? Maple syrup wine? Could be the next big thing...the world needs a good breakfast wine that goes with waffles. As far as other p2 strategies, you might want to review the ChemAlliance virtual plant tour (http://www.chemalliance.org/Handbook/plant/index.asp) and review the case studies related to the terms "viscous" and/or "heat exchange" (to name a few). While the case studies deal almost exclusively with chemical processing, the unit operations are quite similar and you may find some inspiration from how others have dealt with the problems inherent in heating highly viscous liquids (reducing delta T driving force; improving mixing at the boundary layer, e.g. by scraped surface heat exchange; reducing adherence of materials by surface modification e.g., teflon or similar coatings).
Response 4: Here is one company that takes various products and converts them to ethanol:

Great Lakes pollution
Where can I find information about pollution in the Great Lakes?
U.S. EPA's Great Lakes National Program Office is a very good place to start when looking for information about the Great Lakes. They have many resources, including information about each lake. In particular, the Great Lakes Atlas provides comprehensive information about the history, ecosystem, environmental concerns, and joint management of the Lakes. Another good resource is the Great Lakes Center for Environmental Education. They're on the web at http://www.greatlakesed.org/. A good book on the topic is Kehoe, Terence. Cleaning up the Great Lakes : From Cooperation to Confrontation. DeKalb, IL : Northern Illinois University Press, 1997. You should be able to borrow a copy through your local library.

I've been asked to develop a fact sheet discussing the pros and cons of using polystyrene for things such as beverage or food containment. I'm looking for research based information on the environmental and economic aspects of polystyrene use.
As an authoritative source for questions like this, I highly recommend the book The Consumer's Guide to Effective Environmental Choices, which you should be able to obtain through your local library. There is a discussion of styrofoam (polystyrene) on p. 16. For more information about the book, see http://www.amazon.com/exec/obidos/ASIN/060980281X/ref=sib_rdr_dp/104-0579898-7891101. Some web resources of interest include: Polystyrene and the Environment (Polystyrene Packaging Council)
Expanded Polystyrene (Australia)
Arguments Against Polystyrene Foam Products
Some more scientifically oriented papers include: Endocrinically Active Chemicals in the Environment
Plastic Pellets in the Environment: Sources and Recommendations
Technical Factsheet on Styrene
Some journal articles of relevance include the following. You should be able to obtain copies of these through your local library: Zabaniotou, A; Kassidi, E. (2003) "Life cycle assessment applied to egg packaging made from polystyrene and recycled paper." Journal of Cleaner Production 11(5), 549-559.
Ohno, K; Azuma, Y; Nakano, S; Kobayashi, T; Hirano, S; Nobuhara,Y ; Yamada, T. (2001) "Assessment of styrene oligomers eluted from polystyrene-made food containers for estrogenic effects in in vitro assays." Food and Chemical Toxicology 39(12), 1233-1241.

Gasoline Prices
Where can I find sources to document the increase in local gas prices?
The Champaign-Urbana News-Gazette ran several news stories on this in 2000, when prices first spiked. See: Gas prices set based on competition, retailers say
Local gas prices fall following suspension of state gas tax
Gasoline prices soar for summer season
The Energy Information Administration has current and historical statistics on gas prices by region and for certain large metropolitan areas like Chicago. See: Gasoline and Diesel Fuel Update
Retail Gasoline Historical Prices
Weekly U.S. Retail Gasoline Prices
For information on gas prices and how they're set, see: A Primer on Gasoline Prices

definitions
Do you have commonly accepted definitions for the following words?
Several of these terms have been coined by Janine Benyus who has been studying biomimicry. Her book is called Biomimicry: Innovation Inspired by Nature. Amory & Hunter Lovins at the Rocky Mountain Institute have coined a number of these terms as well related to natural capitalism. Visit their web site at http://www.natcap.org/ or reference their books. The titles dealing with this topic are Natural Capitalism: Creating the Next Industrial Revolution, The Natural Advantage Of Nations: Business Opportunities, Innovation And Governance In The 21st Century, and A Road Map for Natural Capitalism, an e-book available through Amazon.com. Gil Friend, who is active in the NPPR may also be of assistance. See http://www.natlogic.com/. He also has a weblog at http://radio.weblogs.com/0109157/. You might also want to check out The Dictionary of Sustainable Management at http://www.sustainabilitydictionary.com/, a project of the Presidio School of Management. If these sources don't help you determine definitions for some of the terms, try using Google's DEFINE search (search syntax is define:word or term). As a test, I used the search string define:"environmental labeling". Google didn't come up with a definition, but did ask if I wanted to search the web. The first result in the web search was to EPA's About Environmental Labeling page, which explains how they define it. A search for define:biomimicry produced no definitions, but clicking on the "search" link provided a link to http://www.biomimicry.org/intro.html, which has a definition at the top of the page. A search for define:sustainability did produce a list of definitions on the web. You can see the results at http://www.google.com/search?hl=en&lr=&q=define%3Asustainability&btnG=Search. If you type the above terms into Google's search box (with or without define: at the beginning), you'll find that a page at or near the top of the results list will give you a generally accepted definition or explanation of the term.
