I waqs doing some homework involving glue and well..after reading so much about Global WArming, i wanted to find out. Which is more harmful to the environment, staples or glue?
Are they biodegradable or non-biodegradable?
Just curious...

All glues may not be bio-degradable , only some special types of glues are bio-degradable. like photocurable glues may serve as a biodegradable tissue adhesive glue usable. in cardiovascular surgery and endoscopic surgery. ...
-Rapidly curable biological glue composed of gelatin and poly(l-glutamic acid)
-Treatment of a perforated peptic ulcer by placing a patch of biodegradable material like a “stamp” on the outside of the stomach is a feasible option.
-Adhesive based on biodegradable acrylates
- Significant advances have been made over the past 20 years in the development of biodegradable polymers. These materials have been developed in a variety of forms, and thus have potential uses in a range of industries. Many of these polymers are suited for adhesive applications, such as environmentally friendly packaging, recyclable envelope adhesives and biomedical devices.
Biodegradable polymers based on renewable resources are also being seen as low-cost alternatives to petroleum-based raw materials. Industries that develop these materials will continue to see growth, as the price of crude oil keeps climbing and the availability of fossil fuels begins to dwindle. Applications for such bio-based materials are widespread in the areas of resins, coatings and adhesives.
The development of biodegradable adhesives goes hand-in-hand with the development of biodegradable plastic products. In order for the finished product to be completely biodegradable, all of its components must be biodegradable. A range of potential biodegradable products is available, including the following.
Packaging materials (trash bags, loose fill foam, food containers)
Consumer goods (egg cartons, razor handles, toys, straws, utensils)
Industrial products (planter boxes, compositing bags, fishing nets, mulch film)
Medical applications (drug-delivery systems, sutures, bandages, orthopedic implants)
Coatings (barrier coatings with low moisture vapor transmission of paper and plastic film)
Hygiene products (flushable sanitary products, diaper backing sheets)
Many of the polymers developed specifically for these products may also be suitable base polymers for biodegradable adhesive systems.

If the glue or gum is from plant, yes, it is biodegradable. But if it is synthetic, some components may not be. Staples are made from aluminium or copper and are degradable (get converted into oxides or some other compounds).
