2020: Waste Management
Grade 9 to Grade 12
An indicator of a healthy ecosystem is its ability to naturally decompose wastes into smaller base components – for example, water, minerals, and nutrients – which are ultimately recycled back into the environment. Compared to other organisms, humans generate a variety of wastes that cannot be processed by natural systems, and as such must be managed through collective human action. Effective waste management systems must engage multiple stakeholders on several fronts and include education, hazard reduction and waste diversion components.
This guide will explore several waste management systems including landfill, compost and recycling programs, incineration, and reduction-diversion strategies.
