Study Notes
JavaScript is Necessary
- The website requires JavaScript to function.
- Users must allow JavaScript in their web browsers to access the service.
- The message indicates that the user's browser is currently blocking JavaScript.
- Enabling JavaScript is essential to sign in and use the platform properly.
- Users can find information on enabling JavaScript within their browser's online help section.
- The message suggests checking if the user's browser supports JavaScript.
Waste Composition
- Waste composition varies depending on location, season, and economic status.
- Load-Count analysis and Weight-Volume analysis are methods for waste characterization.
- Maharashtra has the highest waste collection efficiency in India.
Landfill Design
- Understanding the field capacity of the waste is crucial for determining leachate formation in a landfill.
- Field capacity is the amount of water a soil can hold against the force of gravity.
- The field capacity does not depend on the state of the decomposition of the waste.
Waste Biodegradability
- Volatile solids content is often used to measure the biodegradability of organic waste.
- Volatile solids content is not an exact indicator of biodegradability.
Solid Waste Management (SWM)
- Waste quantification is essential for selecting the right equipment, designing collection routes, and developing material recovery and disposal facilities.
- Ultimate analysis determines the proportion of carbon, hydrogen, oxygen, nitrogen, and sulfur in waste.
- The calorific value of organic material in MSW is determined using a full-scale boiler as a calorimeter or a laboratory bomb calorimeter.
- Processing and transformation are followed by disposal in the functional element of Municipal Solid Waste Management.
Waste Segregation and Storage
- Blue bins are used for segregating paper, cardboard, plastics, wood, metals, and glass.
- The maximum distance between a house and a nearest dustbin for waste storage is 250m.
Waste Processing Technologies
- Incineration is a common onsite processing operation for dry waste at residential dwellings.
- Autoclaving and incineration are processing technologies used for sanitary waste.
- Composting processes are accelerated by adding microorganisms.
- In-vessel composting is typically done only at the household level.
Waste Collection Services
- Haul container systems are used for secondary waste collection.
- In Setout services, homeowners are responsible for returning containers to their storage location.
- The time required per week for a stationary container system (Tw) is estimated using the formula: 0.92 + 0.01 x d/wk, where d is the round-trip haul distance.
- Economic transfer stations are advantageous when disposal sites are more than 10 km away from the city boundary and smaller vehicles are used for waste transport.
Waste Separation
- Waste separation at the source is essential for managing small quantities of waste.
- Size reduction is required to reduce storage space, shipping costs, and achieve uniform product.
- Screening separates waste based on different sizes.
- Density separators separate waste based on different densities.
Waste Densification and Collection Centers
- Densification is a technique used to store and transport waste cheaply.
- Waste drop-off centers require waste generators to bring their own waste to the collection center.
Plastic Recycling
- Air classification separates waste such as HDPE or PET.
- Composite plastics are not typically recyclable.
Glass Recycling
- Glass recycling involves segregation, breaking, trommeling, fluidized bed drying, primary rotary screening, pulverising, and secondary rotary screening.
Incineration Feasibility
- Incineration requires a moisture content that can be reduced through hand-picking large objects, windrow making, turning, and spraying mist spray bio culture.
Factors Affecting Landfill Gas (LFG) Transport
- Permeability, geologic conditions, and landfill cover/liner systems all affect LFG transport mechanisms.
Other Key Points
- Mechanical broom sweepers are used for street cleaning.
- Dry waste is segregated in blue bins according to the Manual of Solid Waste Management.
- The E-Waste Management Rules 2016 regulate the generation, transportation, and disposal of e-waste.
- Public-Private Partnership (PPP) projects are characterized by value for money, efficiency, risk transfer, and a pre-defined time period.
PPP Project Implementation
- PPP projects involve a sequence of: Identification, Full feasibility, Procurement, Operation.
- The DBO model operates a decentralized system of waste management.
Key Success Factors for MSWM
- Integration of the informal sector, public awareness, and waste segregation are all crucial success factors for MSWM projects.
Cost Accounting for ISWM
- Full cost accounting provides a pathway for identifying and assessing the costs related to ISWM.
Analysis Techniques
- Trade-off analysis is used to evaluate the relationship between transfer station capacity and the finances of transportation operations.
