Building a Responsible Economy through ESR

Building a Responsible Economy

Harnessing ESR Principles for Long-term Success

ESR (Environmental, Social, and Governance) is a framework that evaluates the sustainability and ethical impact of an investment or business decision. ESR takes into account a wide range of factors such as environmental impact, social responsibility, labor standards, human rights, and governance practices.

ESR involves evaluating a company’s performance in three areas:

  • Environmental Responsibility: This involves assessing a company’s impact on the environment, such as its carbon footprint, water usage, and waste management practices.
  • Social Responsibility: This involves assessing a company’s impact on society, including its treatment of employees, human rights practices, and community engagement.
  • Governance Responsibility: This involves assessing a company’s internal governance structures, such as its board of directors, executive compensation, and shareholder rights.

ESR projects are initiatives taken by companies or organizations to improve their environmental, social, and governance performance. These projects can take many forms, such as investing in renewable energy, reducing carbon emissions, improving employee working conditions, or implementing more sustainable supply chain practices.

Investment in the Environment and Solid Waste Management sector is an important aspect of ESR. Companies invest in this sector to address issues such as air pollution, water pollution, waste management, and climate change. The investment can take the form of equity, debt, or a combination of both.

In India, there are several companies that invest in ESR funding. Some of the prominent ones include:

  • Tata Capital: Tata Capital is a subsidiary of the Tata Group and provides finance for renewable energy projects and sustainable infrastructure.
  • Acumen: Acumen is a non-profit impact investment fund that invests in companies addressing social and environmental challenges.

Carbon Offsetting Initiatives in India

Carbon Offsetting Initiatives in India

Mitigating Emissions, Empowering Communities

In India, carbon offsetting has gained increasing attention and relevance over the past few years as a tool to mitigate greenhouse gas emissions and address climate change. Carbon offsetting is a mechanism that allows individuals or organizations to offset their carbon emissions by funding projects that reduce or remove greenhouse gas emissions in other parts of the world.

One of the key drivers of carbon offsetting in India is the country’s commitment to the Paris Agreement, which aims to limit global warming to well below 2°C above pre-industrial levels. India has pledged to reduce its greenhouse gas emissions intensity by 33-35% by 2030 compared to 2005 levels, and to achieve 40% of its electricity generation from renewable sources by 2030.

Carbon offsetting projects implemented in India

There are several carbon offsetting projects that have been implemented in India, ranging from renewable energy to afforestation and forest conservation initiatives. Some of the implementing agencies/companies and the scale of the projects are listed below:

  • Wind Energy Projects by Suzlon Energy: Suzlon Energy is one of the largest wind turbine manufacturers in India, and they have implemented several wind energy projects in different parts of the country. The company has commissioned over 11,000 MW of wind energy projects globally, which have resulted in significant carbon emissions reductions.
  • Solar Energy Projects by Tata Power Solar: Tata Power Solar is a leading solar energy company in India that has implemented several large-scale solar projects across the country. The company has commissioned over 5,400 MW of solar energy projects globally, which have resulted in significant carbon emissions reductions.
  • Afforestation Projects by Afforestt: Afforestt is a company that specializes in creating forests on barren lands using a unique plantation technique. They have implemented several afforestation projects in different parts of India, including in urban areas, and have successfully planted millions of trees.
  • Forest Conservation Projects by Wildlife Conservation Trust: The Wildlife Conservation Trust is an organization that works to protect wildlife and their habitats in India. They have implemented several forest conservation projects across the country, which have resulted in significant carbon emissions reductions.
  • Clean Cookstove Projects by Envirofit: Envirofit is a company that manufactures and distributes clean cookstoves in India. The company has implemented several clean cookstove projects in different parts of the country, which have resulted in significant carbon emissions reductions.

The scale of these projects varies, with some being small-scale community projects, and others being large-scale projects implemented by companies and organizations. However, all of these projects have contributed to reducing carbon emissions in India and have made a significant impact on the country’s efforts to mitigate climate change.

The Indian government has also launched several initiatives to promote carbon offsetting, such as the National Clean Energy Fund and the Clean Development Mechanism. Additionally, there are several private organizations in India that provide carbon offsetting services, allowing individuals and organizations to calculate their carbon footprint and offset their emissions by investing in carbon offset projects.

However, there are also concerns regarding the effectiveness and transparency of carbon offsetting, and the potential for offsetting to be used as a substitute for reducing emissions at the source. It is therefore important to ensure that carbon offsetting is used as a complement to, rather than a substitute for, emissions reduction efforts. Additionally, it is important to ensure that carbon offset projects are transparent, credible, and have a positive impact on local communities and the environment.

Solid Waste Management Rules Implemented In Maharashtra

Solid Waste Management Rules in Maharashtra

Understanding MoEF&CC’s SWM Rules Implemented in Maharashtra by Citizens, Communities, and Corporates for Participating Towards a Sustainable Future

In Maharashtra, India, solid waste management has emerged as a critical concern due to rapid urbanization and industrialization the state has experienced. To combat the escalating challenges posed by improper waste disposal, the Maharashtra government is ardently striving to incorporate the stringent solid waste management rules and regulations that the MoEF&CC has prepared for citizens, communities, and corporates.

These solid waste management rules are designed by the Ministry of Environment, Forest and Climate Change (MoEF&CC) to create a comprehensive framework that promotes responsible waste management, minimizes environmental impact, and supports the sustainable development of the state.

Rather than increasing the complexity of this article with technical and jargon-heavy language, we have instead focused on simplifying the rules and regulations. We hope with these bite-sized simplifications, it will be easier for you to understand, digest, and implement these rules and regulations in your own capacity. Towards this end, we have also included some links to the web presence of the concerned authorities.

Solid Waste Management Rules for Citizens:

Citizens are integral stakeholders in the endeavor to establish an effective solid waste management system. Maharashtra will benefit tremendously by continuing to practice the following waste management rules for citizens:

Segregation at Source

Citizens are legally obligated to segregate their waste at the point of generation into distinct categories: wet waste (biodegradable), dry waste (recyclables), sanitary waste, and hazardous waste. This practice simplifies subsequent collection and processing activities.

Use of Bin System

The use of color-coded bins is mandated for waste segregation. Green bins are designated for wet waste, blue for solid/dry waste, red for sanitary waste, and grey/black for hazardous waste. This visually assists waste collectors in accurately sorting and processing waste.

Composting

Maharashtra’s SWM strategy includes strictly following the rules set by the MoEF&CC that emphasize the promotion of home composting initiatives for organic waste. It’s mandatory for bulk waste generators who produce more than 100kg/day of waste to process their own wet waste. Also, now it’s mandatory for bulk waste generators to provide sufficient space and infrastructure for wet waste management. This not only reduces the burden on landfills but also produces nutrient-rich compost for enhancing soil fertility. Some cities provide tax rebates for individuals/societies/institutes who are managing their own wet waste.

Reducing Single-Use Plastics

Citizens are expected to participate in the state’s campaign against single-use plastics. This involves minimizing the usage of plastic bags, cups, and containers, and transitioning to eco-friendly alternatives.

Awareness and Education

The government, in collaboration with local NGOs and active citizen groups, conducts regular awareness campaigns and workshops to educate citizens about the significance of waste segregation, recycling, and proper waste disposal techniques.

Solid Waste Management Rules for Communities:

Communities, encompassing residential complexes, neighborhoods, and local organizations, are vital in ensuring the success of waste management initiatives.

Community Composting

The regulations encourage communities to establish on-site composting units. These units can utilize techniques like aerobic composting, vermicomposting, or bio-gas generation to process organic waste collectively.

Recycling Drives

Communities are encouraged to organize periodic recycling drives to gather recyclable materials. These materials are then directed to authorized recycling facilities, reducing the strain on natural resources.

Collaboration with Municipalities

Communities are expected to collaborate closely with local municipal bodies to ensure efficient waste collection and disposal services. Feedback mechanisms help address any waste management challenges promptly.

Public Facilities

Adequate waste disposal facilities, including bins and waste collection points, should be strategically placed in public areas, parks, markets, and other gathering spaces to discourage littering and promote responsible waste disposal.

Solid Waste Management Rules for Corporates:

Corporates and industries are pivotal in managing solid waste generated from their operations and products. Maharashtra’s solid waste management rules for corporates encompass the following aspects:

Extended Producer Responsibility (EPR)

Corporates are legally mandated to adopt the EPR principle, necessitating them to manage the end-of-life disposal of the products they introduce into the market. This includes establishing collection, recycling, or disposal mechanisms for their products’ waste.

Waste Audits

Regular waste audits are a crucial element of the corporate waste management framework. These audits help identify waste generation patterns, areas for waste reduction, and opportunities for recycling and reusing materials.

Hazardous Waste Management

Industries that produce hazardous waste must strictly adhere to guidelines set by the Maharashtra Pollution Control Board (MPCB). This includes obtaining necessary permits, adhering to safe storage and transportation practices, and ensuring proper disposal of hazardous waste.

Promoting Sustainable Practices

Corporates are encouraged to adopt sustainable practices within their operations. These practices encompass minimizing packaging waste, promoting paperless office environments, sourcing materials responsibly, and implementing energy-efficient processes.

Conclusion

The solid waste management rules established by the MoEF&CC underscore the conutry’s commitment to address the pressing issues of waste accumulation and environmental degradation. Citizens, communities, and corporates of Maharashtra all have pivotal roles to play in the successful implementation of these rules. By adhering to these regulations, Maharashtra can pave the way for a cleaner, healthier, and more sustainable future.

Revenue streams in solid waste management

Unlocking Revenue Potential: Revenue Streams in Solid Waste Management in India

Solid waste management in India is a major challenge due to the large and rapidly growing population, urbanization, and inadequate infrastructure. To finance and sustain solid waste management services, city administrators in India can adopt different financial and revenue models.

Some of the common financial and revenue streams in solid waste management in India are:

User fee model:

In this model, the city administration charges a fee from households and businesses for the solid waste management services provided to them. The fee can be fixed or variable based on the quantity of waste generated by the households or businesses. The user fee model can provide a sustainable revenue stream for solid waste management services and encourage households and businesses to reduce their waste generation.

Example of cities using the user fee model in India:

  • Bengaluru: The Bruhat Bengaluru Mahanagara Palike (BBMP) collects user fees for solid waste management from all households, apartments, and commercial establishments within its jurisdiction. The fees are collected based on the type of waste generated and the size of the property.
  • Pune: The Pune Municipal Corporation (PMC) charges a user fee for solid waste management to all households and commercial establishments. The fee is based on the type of waste generated and the quantity of waste produced.

Open market revenue streams:

City administrators can generate additional revenue streams by selling recyclable materials or byproducts of solid waste processing, such as compost or energy. The sale of recyclable materials can be done through auctions or contracts with private recyclers or waste processing companies. Similarly, compost or energy generated from solid waste can be sold to industries or households for their use. The open market revenue streams model can help offset some of the costs of solid waste management services and create job opportunities in the waste processing sector.

Example of cities using the open market revenue streams model in India:

  • Hyderabad: The Greater Hyderabad Municipal Corporation (GHMC) has implemented a solid waste management system that includes waste-to-energy plants, composting facilities, and recycling units. The GHMC generates revenue from the sale of energy produced by the waste-to-energy plants and the sale of compost and recyclable materials.
  • Surat: The Surat Municipal Corporation has implemented a waste-to-energy plant that generates electricity from the waste generated in the city. The electricity generated is sold to the Gujarat State Electricity Corporation, generating revenue for the municipality.

Public-private partnership (PPP) model:

Under this model, the city administration partners with private companies to provide solid waste management services. The private companies invest in infrastructure and equipment for waste collection, transportation, processing, and disposal, while the city administration provides regulatory oversight and monitoring. The PPP model can leverage private sector expertise and resources to improve the efficiency and effectiveness of solid waste management services.

There are several cities in India that have successfully implemented the PPP model for solid waste management.

Some examples include:

  • Indore: Indore, a city in the state of Madhya Pradesh, has implemented a PPP model for solid waste management in collaboration with a private sector company called Antony Waste Handling Cell. Under this model, Antony Waste is responsible for collecting and transporting waste from households and commercial establishments to the designated landfill sites. The company also provides waste segregation and recycling services.
  • Surat: Surat, a city in the state of Gujarat, has implemented a PPP model for solid waste management in collaboration with a private sector company called Hanjer Biotech Energies Pvt. Ltd. Under this model, Hanjer Biotech is responsible for collecting and transporting waste from households and commercial establishments to the designated landfill sites. The company also provides waste segregation and recycling services.
  • Bengaluru: Bengaluru, a city in the state of Karnataka, has implemented a PPP model for solid waste management in collaboration with a private sector company called Ramky Enviro Engineers Ltd. Under this model, Ramky Enviro is responsible for collecting and transporting waste from households and commercial establishments to the designated landfill sites. The company also provides waste segregation and recycling services.

Overall, the PPP model for solid waste management has been successful in several cities in India, as it has allowed for the efficient provision of waste management services while also promoting private sector participation in the sector. However, there are also some challenges associated with this model, such as ensuring transparency in the selection of private sector partners and the need for effective regulation and monitoring of their performance.

Grants and subsidies:

City administrators can also seek grants and subsidies from the central and state governments, multilateral organizations, or philanthropic foundations to fund solid waste management services. Grants and subsidies can help cover some of the capital and operational costs of solid waste management services, especially for low-income communities that cannot afford user fees.

One example of a grants and subsidies model for solid waste management is the Swachh Bharat Mission (SBM), launched by the Government of India in 2014. Under this program, financial assistance is provided to urban local bodies (ULBs) for various activities related to solid waste management, including procurement of equipment, construction of waste processing facilities, and community awareness campaigns. The funding is provided in the form of grants and subsidies, with ULBs required to provide a matching contribution.

For instance, in the city of Chennai, the SBM has provided a subsidy of 35% of the project cost for the construction of a waste-to-energy plant. Similarly, in the city of Bengaluru, the SBM has provided a grant of INR 61 crore for the construction of a new waste processing facility.

In addition to the SBM, other grants and subsidies models are also being implemented in India to support solid waste management initiatives. For example, the Atal Mission for Rejuvenation and Urban Transformation (AMRUT) program provides funding for various urban infrastructure projects, including solid waste management. Under this program, ULBs are required to prepare detailed project reports and submit them for approval, following which they receive grants for project implementation.

Moreover, many state governments in India also provide grants and subsidies for solid waste management initiatives. For instance, the government of Maharashtra has launched a scheme called the “Mukhyamantri Shuddha Paryavaran Yojana,” under which ULBs are eligible to receive grants for various activities related to solid waste management, including the procurement of equipment, construction of processing facilities, and the implementation of door-to-door waste collection.

Pit Composting and Windrow Composting for Sustainable Organic Waste Management

Pit Composting and Windrow Composting for Sustainable Organic Waste Management

Pit composting and Windrow composting are two common methods of composting organic waste. Let’s look at them in detail.

Pit Composting:

Pit composting is a small-scale method of composting that involves digging a pit in the ground and adding organic waste materials. The pit is covered with soil and left to decompose over time. The capacity of a pit composting system can vary depending on the size of the pit and the amount of organic waste generated. In India, the CPHEEO guidelines recommend the following minimum and maximum capacity for pit composting facilities:

  • Minimum capacity: 100 kg per day
  • Maximum capacity: 5 tonnes per day

Technical guidelines for pit composting in India:

  • Location: Choose a location that is well-drained, away from water bodies, and at a safe distance from residential areas to prevent odor nuisance.
  • Size of the pit: The size of the pit depends on the quantity of waste generated. For a household, a pit of dimensions 1.5m x 1.5m x 1m is sufficient. For larger quantities of waste, the pit can be scaled up accordingly.
  • Lining the pit: The pit should be lined with a layer of concrete to a thickness of at least 5cm to prevent leachate from seeping into the ground.
  • Preparing the composting material: The composting material should be a mixture of brown and green organic waste, such as dry leaves, grass clippings, kitchen waste, and cow dung. The carbon to nitrogen ratio should be between 25:1 and 30:1.
  • Adding the composting material to the pit: The first layer of the composting material should be about 10cm thick. The subsequent layers should be added as the waste is generated.
  • Moisture management: The composting material should be kept moist but not waterlogged. Sprinkle water on the composting material if it appears dry.
  • Turning the compost: The compost should be turned every 10-15 days to aerate it and ensure that it decomposes evenly.
  • Composting time: The composting process takes between 4-6 months. The compost is ready when it is dark brown, crumbly, and has an earthy smell.
  • Using the compost: The compost can be used as a soil amendment in gardens, agriculture, and horticulture.
  • Maintenance of the pit: The pit should be cleaned after every composting cycle. The concrete lining should be checked for cracks and repaired if necessary.

These guidelines can help in setting up a concrete pit composting system that is efficient, easy to maintain, and environmentally friendly.

Windrow Composting:

Windrow composting is a large-scale method of composting that involves piling organic waste materials in long rows, or windrows, and turning them periodically to aerate the compost. The capacity of a windrow composting system can vary depending on the size of the operation and the amount of organic waste generated. In India, the Central Public Health and Environmental Engineering Organisation (CPHEEO) guidelines recommend the following minimum and maximum capacity for windrow composting facilities:

  • Minimum capacity: 5 tonnes per day
  • Maximum capacity: 200 tonnes per day

Technical guidelines for windrow composting in India:

  • Site selection: Choose a site that is well-drained, level, and away from water sources to prevent contamination. The site should also be easily accessible for the transport of organic waste and finished compost.
  • Size of windrow: The size of the windrow will depend on the amount of organic waste generated and the available space. Windrows should be between 1.5 to 2 meters wide and up to 2 meters high. The length of the windrow can vary depending on the amount of organic waste available.
  • Composting materials: The organic waste used in windrow composting should be a mixture of carbon-rich (e.g. dry leaves, straw) and nitrogen-rich (e.g. food waste, green leaves) materials. The ideal carbon-to-nitrogen (C:N) ratio is between 25:1 and 30:1.
  • Windrow construction: Begin by creating a base layer of coarse materials such as twigs or branches to promote air circulation. Then, alternate layers of carbon-rich and nitrogen-rich materials, watering each layer lightly to achieve a moisture content of around 50%.
  • Turning the windrow: The windrow should be turned every 7-10 days to promote aeration and decomposition. Turning can be done using a front-end loader or manually using a pitchfork.
  • Composting time: The composting process can take between 2-6 months, depending on the size of the windrow, moisture content, and temperature.
  • Monitoring: Regular monitoring is essential to ensure that the windrow is decomposing properly. The temperature should be checked using a thermometer, and the moisture content should be monitored using a moisture meter. Adjustments can be made to the windrow, such as adding water or adjusting the C:N ratio, as needed.

Windrow composting is a low-cost and effective way to manage organic waste in India. By following these technical guidelines, you can produce high-quality compost for your garden or farm while reducing waste and promoting sustainability.
