Turning Waste into Carbon Credits: A Guide for Indian Businesses
“Waste is a valuable resource that can be turned into a revenue stream and a means to reduce greenhouse gas emissions.”
In recent years, waste recycling has emerged as an effective strategy for reducing greenhouse gas emissions and earning carbon credits. The process involves diverting waste from landfills and converting it into a useful resource, which reduces the demand for fossil fuels and reduces emissions.
The Verified Carbon Standard (VCS) offers several methodologies for calculating carbon credits from waste recycling projects. These methodologies are designed to ensure that the project is sustainable and results in real emissions reductions. Here are some of the most commonly used methodologies:
- VM0011: Recycling and composting of waste This methodology is used to calculate carbon credits for projects that involve recycling or composting of waste. The methodology takes into account the carbon emissions associated with the landfilling of waste and the emissions avoided through recycling or composting. Projects that qualify for this methodology include recycling of plastics, paper, glass, and other materials.
- VM0008: Methane capture from sewage treatment plants This methodology is used to calculate carbon credits for projects that involve capturing methane from sewage treatment plants. Methane is a potent greenhouse gas that is emitted during the decomposition of organic matter in landfills. By capturing and utilizing the methane, the project reduces emissions and generates carbon credits.
- VM0023: Recycling of construction and demolition waste This methodology is used to calculate carbon credits for projects that involve the recycling of construction and demolition waste. The methodology takes into account the emissions associated with landfilling and the emissions avoided through recycling. Projects that qualify for this methodology include recycling of concrete, bricks, wood, and other materials.
Several waste recycling projects in India have successfully earned carbon credits under these methodologies. Here are some examples:
- Godrej Industries Limited – Waste-to-energy project Godrej Industries Limited implemented a waste-to-energy project that involves processing waste generated by their manufacturing facilities to produce steam and electricity. The project has reduced greenhouse gas emissions by over 100,000 metric tons and generated over 500,000 carbon credits. The project was registered under the VM0011 methodology.
- Chennai Metro Rail Limited – Waste diversion program The Chennai Metro Rail Limited implemented a waste diversion program that involves segregating and composting organic waste generated by the metro stations. The program has diverted over 2,000 metric tons of waste from landfills and generated over 10,000 carbon credits. The project was registered under the VM0011 methodology.
- Noida Authority – Solid waste management project The Noida Authority implemented a solid waste management project that involves the collection, segregation, and composting of waste. The project has reduced greenhouse gas emissions by over 50,000 metric tons and generated over 200,000 carbon credits. The project was registered under the VM0011 methodology.
By implementing waste recycling strategies and working with carbon offset registries, Indian businesses can turn their waste reduction efforts into a valuable asset while also contributing to a more sustainable future. The table below summarizes the waste recycling projects in India that have successfully earned carbon credits:
| Project Name | GHG Reduction (MT CO2e) | Carbon Credits Generated | VCS Methodology Used |
|---|---|---|---|
| Godrej Industries Limited | 100,000 | 500,000 | VM0011 |
| Chennai Metro Rail Limited | 2,000 | 10,000 | VM0011 |
| Noida Authority | 50,000 | 200,000 | VM0011 |
In conclusion, waste recycling can be an effective way for businesses to reduce their carbon footprint and generate carbon credits. The VCS offers several methodologies that businesses can use to calculate their emissions reductions and earn carbon credits. By implementing sustainable waste recycling practices, Indian businesses can contribute
Sample calculations for estimating GHG reduction using the VM0011 methodology:
| Parameter | Value |
|---|---|
| Baseline year | 2015 |
| Project start year | 2017 |
| Project end year | 2032 |
| Project duration | 15 years |
| Total waste diverted | 50,000 tonnes/year |
| Methane generation rate | 60 m3/tonne |
| Methane destruction rate | 90% |
| Carbon dioxide equivalent | 25 |
Using the above parameters, the calculation for GHG reduction would be as follows:
- Methane emissions avoided per year = Total waste diverted x Methane generation rate x Methane destruction rate Methane emissions avoided per year = 50,000 x 60 x 0.9 = 2,700,000 m3
- CO2 equivalent emissions avoided per year = Methane emissions avoided per year x Carbon dioxide equivalent CO2 equivalent emissions avoided per year = 2,700,000 x 25 = 67,500,000 kg CO2e
- Total CO2 equivalent emissions avoided over the project duration = CO2 equivalent emissions avoided per year x Project duration Total CO2 equivalent emissions avoided over the project duration = 67,500,000 x 15 = 1,012,500,000 kg CO2e
- Total carbon credits generated = Total CO2 equivalent emissions avoided over the project duration / 1000 Total carbon credits generated = 1,012,500,000 / 1000 = 1,012,500 carbon credits
This is just a sample calculation, and actual calculations may vary depending on the specific parameters of the project. It’s important to consult the VCS methodology and follow the guidelines closely to ensure accurate and reliable GHG reduction calculations.
