Biodegradable waste includes any organic matter in waste which can be broken down into carbon dioxide, water, methane, compost, humus, and simple organic molecules by micro-organisms and other living things by composting, aerobic digestion, anaerobic digestion or similar processes. It mainly includes kitchen waste (spoiled food, trimmings ...
Ecology portal. v. t. e. Plastic pollution is the accumulation of plastic objects and particles (e.g. plastic bottles, bags and microbeads) in the Earth's environment that adversely affects humans, wildlife and their habitat. [ 1 ][ 2 ] Plastics that act as pollutants are categorized by size into micro-, meso-, or macro debris. [ 3 ] Plastics ...
Almost all plastic is non-biodegradable and without recycling, spreads across the environment [108] [109] where it causes plastic pollution. For example, as of 2015, approximately 8 million tonnes of waste plastic enters the oceans annually, damaging oceanic ecosystems and forming ocean garbage patches. [110]
Plastic recycling is the processing of plastic waste into other products. [ 1 ][ 2 ][ 3 ] Recycling can reduce dependence on landfill, conserve resources and protect the environment from plastic pollution and greenhouse gas emissions. [ 4 ][ 5 ] Recycling rates lag behind those of other recoverable materials, such as aluminium, glass and paper.
Biodegradation is the naturally-occurring breakdown of materials by microorganisms such as bacteria and fungi or other biological activity. [ 35 ] Composting is a human-driven process in which biodegradation occurs under a specific set of circumstances. [ 36 ] The predominant difference between the two is that one process is naturally-occurring ...

Fatberg. A fatberg is a rock-like mass of waste matter in a sewer system formed by the combination of flushed non- biodegradable solids (such as wet wipes) with fat, oil, and grease (FOG) deposits. [1][2][3] The handling of FOG waste and the buildup of its deposits are a long-standing problem in waste management, with "fatberg" a more recent ...
