Biodegradable and compostable alternatives to conventional plastics.
Packaging waste forms a significant part of municipal solid waste and has caused increasing environmental concerns, resulting in a strengthening of various regulations aimed at reducing the amounts generated. Among other materials, a wide range of oil-based polymers is currently used in packaging applications. These are virtually all non-biodegradable, and some are difficult to recycle or reuse...
متن کاملstarch-based biodegradable polymers and packaging plastics
it seems that today whole world seems to be wrapped in plastics. almost every product we buy, most of the food we eat and many of the liquids we drink, come encased in plastics. the environmental impact of persistent plastic wastes is evoking more global concern as alternative disposal methods are limited. incineration may generate toxic air pollution, and satisfactory landfill sites are limite...
متن کاملDegradation of Biodegradable/Degradable Plastics in Municipal Solid-Waste Landfill
This paper provides information about biodegradability of biodegradable/degradable materials advertised as 100%-degradable or certified as compostable in a municipal solid-waste landfill. It describes a 12month experiment with five samples that took place in a landfill. The results, demonstrated that the polyethylene sample with the additive (samples 1) and sample labelled as 100% degradable (s...
متن کاملThe second green revolution? Production of plant-based biodegradable plastics.
Biodegradable plastics are those that can be completely degraded in landfills, composters or sewage treatment plants by the action of naturally occurring micro-organisms. Truly biodegradable plastics leave no toxic, visible or distinguishable residues following degradation. Their biodegradability contrasts sharply with most petroleum-based plastics, which are essentially indestructible in a bio...
متن کاملPreparation and Characteristics of Paper-based Biodegradable Plastics
The aim of this work was to make biodegradable plastics from renewable resources. Paper-based biodegradable plastics were produced via a sol-gel process by using zinc chloride solution. The optimum conditions were a zinc chloride concentration of 65%, reaction temperature of 70 °C, reaction time of 5 s, aging time of 3 h, and glycerol concentration of 10%. Fourier transform infrared spectroscop...
