WASTE IS NOT UNIQUE!
What we cannot use, we term as ‘waste’. However, when we have to manage waste, all waste is not the same.
Each type of waste has to be handled differently. The way waste reacts with nature determines the type of the waste it is.
WHAT ARE THE BASIC SOURCES OF WASTE?
WHAT IS THE VALUE CHAIN FOR MUNICIPAL WASTE MANAGEMENT?
Value chain of waste management is a five-step process.
Ideal case of value chain for municipal solid waste management can be elaborated through the following flow diagram:
WHAT IS VALUE CHAIN FOR 100% COLLECTION OF SEGREGATED WASTE?
Ideal condition is assumed to have 100% segregated waste from 100% households.
Following waste flow diagram explains the practical on field scenario for waste management:
WHAT IS VALUE CHAIN FOR WASTE PROCESSING?
Waste segregation plays an important role in defining the processing value chain. There are two approaches followed for processing of the waste. Both of which have its own positives and negatives.
Balancing between decentralized and centralized waste processing systems reflects in better financing for overall waste management as well as resource management.
Overall value chain and probable options for processing of various types of waste is as given in flow diagram below:
WHAT ARE THE PROS AND CONS OF THE DECENTRALIZED AND CENTRALIZED WASTE PROCESSING SYSTEMS?
Centralized Waste Processing Systems
Positives | Negatives |
Decentralised Processing systems
Positives | Negatives |
