History

Waste management is the overall system of handling waste from creation to disposal, while recycling is a key part of it, involving processing used materials into new products, saving resources, and cutting pollution by diverting waste from landfills. Together, they aim to minimize environmental impact by reducing, reusing, and recycling waste, turning trash into valuable resources.

Mechanical recycling is less energy intensive than chemical recycling. Chemical recycling needs more energy and produces more CO2 emissions. Mechanical recycling shreds plastic waste and doesn't' use toxic chemicals. Chemical recycling needs toxic chemicals (acids and solvents) to dissolve the plastics.

Composting programs turn organic waste into soil-enriching compost, reducing landfill use and pollution, with types including municipal curbside pickup, community drop-off sites, and home systems. These programs educate residents, create green spaces, foster local food systems, and build community resilience, offering options from opt-in services to mandatory collection, all converting food scraps and yard trimmings into valuable soil amendments for parks, gardens, and local agriculture.

In consumer electronics, the process of re-manufacturing or refurbishment of second-hand products can be seen as upcycling because of the reduced energy and material consumption in contrast to new manufacturing. The re-manufactured product has a higher value than disposing or downcycling it.
