Most efficient waste transport solutions

The transport of waste kept at storage depots at frequent intervals is crucial to prevent garbage bins/containers from overflowing and to ensure waste is not scattered on the streets. Clean conditions can be upheld in cities/towns only if the routine removal of waste from temporary storage bins is guaranteed. Transportation system has to be so designed that it is efficient and cost effective. 

Municipalities around the world are exploring efficient waste transport solutions to streamline their waste collection processes.

Following are the main issues to be addressed for effective transportation system

1. Irregular transportation.
2. Underutilization of fleet of vehicle.
3. Open trucks.
4. non-routing vehicle.

Measures to be taken to improve the transportation system for SWM

Solid waste collected at several locations in the city is required to be transported to treatment and disposal site. Guidelines of Solid Waste Management Act in respect of transportation are given below: 

The success of a city’s waste management system depends heavily on efficient waste transport solutions.

• Vehicle used for transportation of wastes shall be covered.

• Waste should not be visible to the public or exposed to the open environment, preventing its dispersion.

• The following criteria must be fulfilled: The storage facilities established by municipal authorities shall be attended to daily for waste cleaning.

• Collection and transportation vehicles shall be designed to minimize multiple handling of waste before final disposal.

• Transportation system for solid waste management is designed keeping above requirement in mind.

• The transport Vehicle should be strong durable and water tight, it should made of steel with smooth interior surface.

Implementing efficient waste transport solutions can significantly improve the overall waste disposal process.

Transportation vehicles with their capacity and working-Animal carts, Auto vehicles, Tractors or Trailers, Trucks, Dumpers, Compactor vehicles.

1. Animal Carts: These vehicles are driven by horses, donkeys and other animals used for collecting the waste. The capacity of these vehicles varies from 2 to 4 m3 There is no need of fuel for collection of waste also very low capital and operational cost compared with motor vehicles. The slow speed of animal carts restricts their operational range to approximately 3 km. In streets with heavy traffic, animal carts may interfere with traffic.

2. Auto Vehicles: The two-stroke, three-wheel auto vehicle is a very common means of transportation in several developing countries. Auto vehicles having capacity 2 to 4 m3 are used in waste transportation. Its relatively high speed which gives this system an operating radius of about 10 km. 

3. However, the auto vehicles do not operate well on rough, unpaved roads. If the road system to the disposal site is inadequate, auto vehicles should discharge at either transfer facilities or processing plants.

4. Tractors or Trailers: The agricultural tractor is one of the most utilised motor vehicles for collecting waste in economically developing countries. The tractors having capacity 6 m3 are useful for collecting the refuse from household or storage points. Some of the advantages of tractors are: relatively low capital cost, capacity to transport a large load, readily available maintenance facilities, ready to use on a landfill due to large tyres.

5. Trucks: This type of vehicle is primarily designed for the transport of construction materials. However, it is also widely used for the collection of wastes. Trucks having capacity 5 to 6 m3 are useful for collection and transportation of waste from communal sites. The body of the truck is usually made of steel and is suitable to carry high-density materials such as bricks and aggregates. The advantages of using truck are: It is relatively inexpensive, it is sturdy and easily available, it has good ground clearance and it performs well on rough roads. 

6. Dumpers: Dumpers are used for collection and transportation of large quantity of solid waste. The main advantage of using dumper is that it can be emptied immediately due to hydraulic mechanism. This type of vehicle has a body capacity of approximately 12 m³

7. Compactor vehicles: A compactor vehicles compact the solid waste by using mechanical pressure which reduce the volume of waste. The capacity of this vehicle varies from 5 to 10 m3.

Waste management agencies need to adopt efficient waste transport solutions to minimize environmental impact.

Transfer stations: meaning, necessity, location

Transfer station: These are the open or closed structures built by competent authority at various Locations within the city, where waste collected by hauling vehicles, is initially transferred to these stations beforehand. to loading into large vehicles.

A transfer station is a facility or processing site for the temporary storage of waste. It is commonly used as a location where local waste collection vehicles unload their waste before it is transferred to larger vehicles. These larger vehicles then transport the waste to its final disposal site, such as an incinerator, landfill, hazardous waste facility, or recycling center.

By using efficient waste transport solutions, cities can lower their carbon footprint and improve sustainability.

Location

1. Waste Dispersion / Pollution: The site should be chosen to prevent any nuisance to nearby areas and should not be situated in densely populated or residential zones. areas. It should not be located in thickly populated and residential area.

2. Haul Distance: It should be constructed at suitable locations so as to minimize haul distances. It should be near to disposal site.

3. Historical Site: It should be situated away from heritage locations. 

4.Traffic Movement: It should be in an area with smooth traffic flow.

5. Electricity: Electricity should be available at the site of transfer station. 

6. Land Cost: It should be located in an area where land and property rates are affordable.

The design of vehicles used in waste management plays a crucial role in achieving efficient waste transport solutions.

Necessity of transfer stations

Transfer stations are necessary due to following reasons 

1. Larger volume of municipal solid waste from urban market is not possible to transport directly to disposal sites for land filling, etc. from collection points. Therefore, waste is temporarily stored at a location away from the generation points. At these sites, waste is received from smaller collection vehicles, compacted, and then loaded into larger vehicles for long-distance transportation to the disposal site.

2. Thus transfer station results in improvement in collection equipment by minimizing transportation cost, time and reduction in volume.

3. They prevent the scattering of MSW. 

4. To have ease in proper storage and collection of MSW from different locations. 

5. To prevent nuisance due to scattered solid waste to nearby area. 

Organizational Structure of Solid Waste Management

The organizational structure of solid waste management is as follows

1. Ministry of Environment and Forests: The Ministry of Environment and Forests is responsible for formulating environmental policies at the national level, including waste management. The Ministry oversees all activities in the MSWM sector, ensuring its effective implementation.

2. Central Pollution Control Board: The Central Pollution Control Board monitors all activities that have the potential to pollute the environment, including municipal solid waste management across the country. It has divisions in each state that report to the CPCB on environmentally hazardous activities, the actions taken to address them, and the improvements made by industries and the public towards a cleaner environment.

3. State Pollution Control Board: The State Pollution Control Board monitors all activities that could potentially pollute the environment, including overseeing municipal solid waste management within the state. It reviews the Environmental Impact Assessment conducted by agencies before the construction of landfill sites, installation of incinerators, or any other processing plants. The Board organizes public participation meetings to raise awareness about the proposed projects and their benefits. Public involvement is crucial to ensure there is no opposition once the project begins.

4. City Corporation: The City Corporation is responsible for creating solid waste management policies, setting targets, and defining objectives. They oversee the management of solid waste within the city and are accountable to the State Board and Central Pollution Control Board. The City Corporation also has the authority to privatize the solid waste management sector.

5. Private Formal Sector: The private formal sector is responsible for waste collection, transferring waste to trucks, and transporting it to designated dump yards. They are tasked with disposing of waste using methods such as alternative layering of waste and soil, along with spraying it with EM solution and water.

6. Private Informal Sector: The informal sector in the city is extensive and plays a crucial role in municipal solid waste management (MSWM). It consists of rag pickers who collect recyclable waste from community bins and landfills and sell it to larger dealers or recycling factories.

Vehicle utilization is key in achieving the most efficient waste transport solutions by ensuring underutilization is minimized.
