Plastic Bags: Hazards and Mitigation

Failure to sterilize in plastic bags.

The ideal container for discarded cultures and other contaminated materials which require autoclaving to render them safe should be reasonably cheap, resistant to corrosion, leak-proof, and capable of allowing the passage of steam to all parts of its contents. Perhaps because of the difficulty of meeting all these requirements with the metal containers which have traditionally been used some la...

Eco-Impact of Plastic and Paper Shopping Bags

This article describes the study of the eco-impact of plastic and paper bags using the life cycle impact assessment (LCIA) technique under three different options: usage and disposal criteria with the existing usage behavior to reuse and governmental policies to recycle (option1), usage and disposal criteria as per consumers’ perceptions if systems are in place (option2) and usage and disposal ...

Environmental Effect on Biodegradability of Plastic and Paper Bags

Biodegradation refers to the chemical dissolution of materials by microorganisms or other biological means. Biodegradable materials are those that can be consumed by microorganisms whereas biodegradability of a material refers to the ability of that material to be decomposed by biological agents, especially bacteria. Plastics are synthetic or semi – synthetic long chain polymeric molecules that...

Compounds from multilayer plastic bags cause reproductive failures in artificial insemination

The problem started suddenly and did not appear to be related to the quality of the ejaculates, disease, alterations of body condition or any other apparent reasons. Subsequent studies determined that the problem was t...
