Other biodegradable wastes include human waste, manure, sewage, sewage sludge and slaughterhouse waste. In the absence of oxygen, much of this waste will decay to methane by anaerobic digestion. [4] In the UK, 7.4 million tonnes of biodegradable waste was sent to landfill in 2018 having reduced from 7.8 million tonnes in 2017. [5]
The term Biodegradable Plastics refers to materials that maintain their mechanical strength during practical use but break down into low-weight compounds and non-toxic byproducts after their use. [18] This breakdown is made possible through an attack of microorganisms on the material, which is typically a non-water-soluble polymer. [4]
A plastic is considered biodegradable if it can degrade into water, carbon dioxide, and biomass in a given time frame (dependent on different standards). Thus, the terms are not synonymous. Not all bioplastics are biodegradable. [44] An example of a non-biodegradable bioplastic is bio-based PET. PET is a petrochemical plastic, derived from ...

By definition, biodegradable materials are formed or organic compounds which can thus be broken down by living organisms, such as bacteria, fungi, or water molds, and reabsorbed by the natural environment. [13] Whether a material is biodegradable is determined by its chemical structure, not the origin of the material from which it is made. [14]

In addition to tissue engineering, biodegradable polymers are being used in orthopedic applications, such as bone and joint replacement. [30] A wide variety of non-biodegradable polymers have been used for orthopedic applications including silicone rubber, polyethylene, acrylic resins, polyurethane, polypropylene, and polymethylmethacrylate ...
