Mixed waste can also be defined as a type of waste which includes recyclable materials and organic materials. [21] Some examples of mixed waste in this context include a combination of broken glassware, floor sweepings, non-repairable household goods, non-recyclable plastic and metal, and clothing and furnishings. Additionally, ashes and soot ...

'Repurpose' and 'Recycle' involve maximum usage of the materials used in the product, and 'Recover' is the least preferred and least efficient waste management practice involving the recovery of embedded energy in the waste material. For example, burning the waste to produce heat (and electricity from heat).
"Recyclate" is a raw material sent to and processed in a waste recycling plant or materials-recovery facility [50] so it can be used in the production of new materials and products. For example, plastic bottles can be made into plastic pellets and synthetic fabrics. [51]
Waste can be hazardous because it is toxic, reacts violently with other chemicals, or is corrosive, among other traits. [1] As of 2022, humanity produces 300-500 million metric tons of hazardous waste annually. [2] Some common examples are electronics, batteries, and paints. An important aspect of managing hazardous waste is safe disposal.
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 ...
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.
Agricultural waste, on the other hand, is a secondary raw material. They are residual (waste) streams from an existing industry that can serve as raw materials for new applications. Increasingly reusing materials as raw materials for the production process contributes to the EU goal of achieving a circular economy by 2050. [31]
