PROCESS OF SOURCE SEPERATION
(i) Product reuse: Using reusable products, instead of their disposal equivalents, reduce the amount of materials that are to be managed as wastes. An example of product reuse is the reusable shopping bag.
(ii) Material volume reduction: Reducing the volume of material used changes the amount of waste entering the waste stream. This helps in controlling the waste generated and its disposal. For example, buying in bulk or using large food containers reduces the amount of packaging waste generated.
Toxicity reduction: Source reduction reduces the amount of toxic
constituents in products entering the waste stream and reduces
the adverse environmental impacts of recycling or other waste management activities. For example, substitution of lead and
cadmium in inks (solvent-based to water- based) and paints is a source
(iv) Increased product lifetime: Source reduction facilitates the use of products with longer lifetime over short-lived alternatives that are designed to be discarded at the end of their useful lives. Put differently, it encourages a product design that allows for repair and continued use rather than disposal. Manufacturing long-life tyres is a good example of increasing product lifetime.
(v) Decreased consumption: This refers to the reduced consumption of materials that are not reusable (e.g., using a reusable shopping bag instead of picking up plastic bags from the store). Consumer education about the materials that are difficult to dispose of or are harmful to the environment is essential. Buying practices can thus be altered (e.g., buying in bulk) to reflect environmental consciousness.
