The 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 کاملBiodegradable 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 کاملThe Utilization of Activated Sludge Polyhydroxyalkanoates for the Production of Biodegradable Plastics
Sequencing batch reactor (SBR) systems were used for the development of a system and operating procedures for the high production and storage of polyhydroxyalkanoates (PHAs) by wastewater treatment (activated sludge) bacterial cultures. The systems were maintained at a nominal hydraulic retention time (HRT) of 10 hours, and a temperature of 20°C. The solids retention time (SRT) was maintained a...
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...
