•Wastivity of the system is defined as the ratio of the waste to the input.
•Wastivity= Waste / Input
•Gross wastivity= Total waste generated/ Total input.
•All waste is not the waste, some part of it can be recycled.
•Net waste={Total waste generated}-{Waste recycled within the system}.
•Net wasitivity= Waste which cannot be recycled/ Total input.
•Wastivity assesses the productivity for each type of input. Both wasitivity and productivity are complementary to each other.
Issues to be addressed
•Quick identification of the waste generated.
•Separation of different types of waste.
•Economic reduction.
•Efficient collection and handling.
•Recycling, and effective disposal without affecting the environment.
•Designing a suitable ‘waste control programme’.
