Chapter - 10 Solid Waste Management Preparation of Feasibility Report10.8 WASTE CHARACTERISTICSFor preparing the DPR the physical and chemical characteristics of waste need to bedetermined after testing. Such laboratory reports shall form part of the DPR. For preparing FR,the average values may be adopted based on results of the testing done in other cities of theState. The parameters on which data may be obtained are as follows:10.8.1 Physical Characteristicsa) Per capita solid waste generationb) Biodegradable quantity of wastec) Non-biodegradable quantity of wasted) Moisture content (% by weight)e) Average ash content andf) Calorific value of wasteg) Quantity and type of recyclable wasteh) Density (Kg/M3) & composition of waste10.8.2 Chemical Characteristicsa) Organic matter (%)b) NPK values (%)c) C/N ratiod) Calorific value (Kcal/Kg)Chemical characteristics of MSW may be given in a table as annexure of the DPR.10.9 SYSTEM DESIGN OF SOLID WASTE MANAGEMENT10.9.1 ApproachThe approach to solid waste management focuses on:i. Segregation of waste at source into biodegradable, non-biodegradable waste categoriesii. Appropriate waste collection (both door to door & community bin system) and storageiii. Primary and cecondary transport of the waste to transfer stations (TS) and or disposalsite.iv. Processing and treatment of the MSW for recovery of material & energy.v. Minimizing the waste to be disposed through sanitary land filling.vi. Public – Private partnership for economic sustainability and proper handling andmanagement of waste.vii. Decentralized / centralized processing of biodegradable waste to compost to utilize itsnutrient valueviii. Revenue earning from recyclable / reusable waste with the involvement of scvengers(above the age of 18 years), NGOs / CBOs:ix. The management of SWM can be divided into four functional units Segregation at source, collection and storage at source Transfer and transport Processing and treatment76
