Biodegradable waste can be found in municipal solid waste (sometimes called biodegradable municipal waste, or as green waste, food waste, paper waste and biodegradable plastics). Other biodegradable wastes include human waste , manure , sewage , sewage sludge and slaughterhouse waste .
Biodegradable technology is established technology with some applications in product packaging, production, and medicine. [31] The chief barrier to widespread implementation is the trade-off between biodegradability and performance. For example, lactide-based plastics are inferior packaging properties in comparison to traditional materials.
It has shown a significant benefit in allowing food producers and retailers to have full real time visibility of their supply chain. Plastic packaging being used is usually non-biodegradable due to possible interactions with the food. Also, biodegradable polymers often require special composting conditions to properly
Examples of long-term ecobrick applications include: Raised gardens: Ecobricks are laid horizontal and completely covered [67] Raised benches: Two or three levels of horizontally laid ecobricks to make seats and benches. [22] Food Forest Play Parks: A combination of raised beds and benches to make a public green space, ideally filled with ...
Biogas captured from biodegradable green waste can be used as biofuel. Green waste can be composed of non-food crops, which decompose to produce cellulosic ethanol. It can also help reduce the necessity of petroleum gases, which produce large amounts of greenhouse gases, such as carbon dioxide, when burned.
Unlike in landfill, where it is mixed with other (non-biodegradable) materials, food waste decomposing in a compost does not release harmful gases. [104] Similarly to compost created from other waste sources, composted food waste can be used to return nutrients to the soil if spread on the garden (see uses of compost).

Examples of emerging bioproducts or biobased products include biofuels, bioenergy, starch-based and cellulose-based ethanol, bio-based adhesives, biochemicals, bioplastics, etc. [8] [9] Emerging bioproducts are active subjects of research and development, and these efforts have developed significantly since the turn of the 20/21st century, in ...
