Acceleration and promotion of projects for recovery of energy from urban waste is our prime objective.
The increasing industrialization, urbanization and changes in the pattern of life, which accompany the process of economic growth, give rise to generation of increasing quantities of wastes leading to increased threats to the environment.
In recent years, technologies have been developed that not only help in generating substantial quantity of decentralized energy but also in reducing the quantity of waste for its safe disposal.
In developed countries, environmental concerns rather than energy recovery is the prime motivator for waste-to-energy facilities, which help in treating and disposing of wastes. Energy in the form of biogas, heat or power is seen as a bonus, which improves the viability of such projects. While incineration and biomethanation are the most common technologies, pyrolysis and gasification are also emerging as preferred options.
A common feature in most developed countries is that the entire waste management system is being handled as a profitable venture by private industry or non-government organizations with tipping fee for treatment of waste being one of the major revenue streams
The major Advantages for adopting technologies for recovery of energy from urban wastes is to reduce the quantity of waste and net reduction in environmental pollution, besides generation of substantial quantity of energy. According to a recent estimate about 42 million Tonnes of solid waste (1.15 T pd) and 6000 cubic metres of liquid waste are generates every year by our urban population.
To create a conducive conditions and environment, with fiscal and financial regime, to develop, demonstrate and disseminate utilisation of wastes for recovery of energy; and To harness the available potential of MSW-to-energy by the year 2017
Energy from Waste : The Bio-Char Route : Trash to Treasure
We Humans tend to make the process as complicated as possible by trying to improve on nature in complex machines but a simple approach is still possible There are enough natural agencies, which are too keen to help us in this endeavor. Science has revealed these tools and we must use their potential to achieve the urgent call of nature
· To Mitigate energy-related environmental problems.
· Create a local recycling systems for waste utilisation
Renewable Energy Potential of Waste (In MW’s)
1. Distillery 350 MW
2. Sugar 285 MW
3. Paper and Pulp 058 MW
4. Dairy 022 MW
5. Poultry 044 MW
6. Starch 040 MW
7. Slaughter house 100 MW
Generation of waste
In developing countries biomass is and will remain a major source of energy. In India alone about 200 million tonnes are contributed from agro processing industries. Since these wastes are generated in a dispersed manner and as residue without any associated commercial production costs they are either unused or used very inefficiently. Disposal of this waste is causing environmental degradation. In agriculturally based countries, huge quantities of biomass waste are generated.
- Waste Management, Air pollution
- Farm/fields in urban areas
- Agro-Processing Units
- Urban vegetable marketplaces
- Slaughter Houses
Objectives : Disposal
- We emphasise localised recycling of this waste as resources as well as energy
- Minimise environmental degradation due to its improper disposal, and to conserve the environment
- To reduce environmental degradation due to improper disposal of household and agro-residue waste
- Utilise household and agro-residue waste for biomass energy supply through localised recycling systems
- Utilisation of biomass waste generated for its use as a source of decentralized energy.
- By value-added products, for enhancing environmental conservation.
- Rural cottage agro-industries and their associations
- Local government and municipal organizations
- NGOs, self help groups (SHGs)
- Low income small, and tiny agro-based industries mostly in the unorganized sector
- Poor farmers, rural households
- Polluting, unhygienic environmental working conditions, local environment
- Utilisation of biomass and other local available wastes…
- Decentralized production of renewable energy sources…
- Improved working conditions…
- Cleaner local as well as global environment
