Larger capacity vehicles should transport waste from the secondary or tertiary collection point (depot or transfer station) to the processing and treatment facility or landfill. The types of vehicles should synchronise well with containers placed at depots or transfer stations to prevent multiple handling of waste. The selection of the type of vehicles should Vehicles […]
Secondary storage
CONCEPT OF BIN-LESS AREA OR CITY Wherever possible, it is advisable to synchronise primary collection and secondary collection, thereby avoiding the need for secondary storage bins or depots. Secondary storage Storage depots are required for secondary collection of waste in cities where the bin-less system is not adopted. In most cities, the following types of […]
Collection and transportation
•The compactor is an appropriate vehicle for collecting biodegradable and recyclable component of MSW •Skip loaders/ Hook loaders are preferred for collecting inert waste or Construction and Demolition waste •Waste may be transferred to the transfer station if the processing site is located at least 15 kms away from the city Windrow composting or vermicomposting. […]
Vehicles and equipment for Primary Collection
Primary collection vehicles should meet local requirements. Before selecting a vehicle for primary collection, it is advisable to assess the amount of waste generated, local climatic conditions, topography of the area, and available facilities for repair and maintenance of vehicles.

Source Segregation
The SWM Rules, 2016 defines segregation as sorting and separate storage of various components of solid waste namely •biodegradable wastes including agriculture and dairy waste, •non biodegradable wastes including recyclable waste, •non- recyclable combustible waste, •sanitary waste and non recyclable inert waste, •domestic hazardous wastes •construction and demolition wastes. At a minimum level, indicated as […]
Classification of Solid Wastes
According to their Properties Biodegradable solid wastes are those that can be broken down (decomposed) into their constituent elements by bacteria and other micro-organisms. Food waste, manures and waste from producing crops are the main biodegradable wastes. Non-biodegradable (also sometimes called inorganic) solid wastes are those thatdo not decompose by microbial action. These wastes include plastic containers, […]

Elements of MSW Management
The activities associated with the management of municipal solid wastes from the point of generation to final disposal can be grouped into the six functional elements: 1.Waste generation 2.Waste handling and sorting, storage and processing at the source 3.Collection 4.Sorting, processing and transformation 5.Transfer and transport 6.Disposal. 1. Waste Generation: Waste generation encompasses activities in […]
Municipal Solid Wastes (MSW)
With this increasing population, municipal solid waste management (MSWM) in the country has emerged as a challenge. According to Central Pollution Control Board (CPCB), 1,43,449 tonnes per day (TPD) of MSW was generated in India during 2014–2015, with an average waste of 0.11 kg/capita/day Integrated Solid Waste Management (ISWM) Hierarchy Register & Download PDF for Educational […]
Low Impact Development Design (LID)
The basic LID strategy for handling runoff is to reduce the volume and decentralize flows. This is usually best accomplished by creating a series of smaller retention or detention areas that allow localized filtration instead of carrying runoff to a remote collection area for treatment. The basic LID strategy is explained schematically in figure Register & […]
