Plastic pollution on land poses a threat to the plants and animals – including humans who are based on the land. [87] Estimates of the amount of plastic concentration on land are between four and twenty three times that of the ocean. The amount of plastic poised on the land is greater and more concentrated than that in the water. [88]
Biofouling or biological fouling is the accumulation of microorganisms, plants, algae, or small animals where it is not wanted on surfaces such as ship and submarine hulls, devices such as water inlets, pipework, grates, ponds, and rivers that cause degradation to the primary purpose of that item.
Wastewater treatment plants only remove an average of 95–99.9% of microbeads because of their small design. This leaves an average of 0–7 microbeads per litre being discharged. [102] Considering that the treatment plants of the world discharge 160 trillion liters of water per day, around 8 trillion microbeads are released into waterways ...
Furthermore, plastic bottles and plastic bags that end up in landfills are frequently consumed by animals, which then clogs their digestive systems and leads to death. [4] Because of the substantial growth in plastic consumption, biodegradable additives are becomingly increasingly necessary to increase the rate of degradability of common plastics.
Bespoke biofilters have been developed and commercialized for the treatment of animal wastes, [13] landfill leachates, [14] dairy wastewater, [15] domestic wastewater. [ 16 ] This process is versatile as it can be adapted to small flows (< 1 m3/d), such as onsite sewage [ 17 ] as well as to flows generated by a municipality (> 240 000 m3/d). [ 18 ]
Plastic degradation in marine bacteria describes when certain pelagic bacteria break down polymers and use them as a primary source of carbon for energy. Polymers such as polyethylene (PE), polypropylene (PP), and polyethylene terephthalate (PET) are incredibly useful for their durability and relatively low cost of production, however it is their persistence and difficulty to be properly ...

Plastic Pipe lengths manufactured in Australia by extruding HDPE material.. Plastic pipe is a tubular section, or hollow cylinder, made of plastic.It is usually, but not necessarily, of circular cross-section, used mainly to convey substances which can flow—liquids and gases (fluids), slurries, powders and masses of small solids.
