Compressed Biogas (CBG) from cow dung, Napier grass, and fresh mud is an expanding industry with huge scopes and potentials for new ventures of the entrepreneurs. With the increase in environmental awareness and escalating energy prices, the demand for cleaner sources of renewable energy has been rising continuously. Compressed Biogas (CBG) from organic waste materials comprising cow dung, Napier grass from agricultural fields, and fresh mud can offer a clean alternative. This business provides profitability as well as an opportunity to contribute to a greener economy for startups.

Why Startups Should Invest in Compressed Biogas Manufacturing

1.      Sustainability and Environmental Impact

The foremost reason for entrepreneurs to invest in CBG production is its role in sustainability. Biogas is a renewable source of energy, which helps in reducing the dependency on fossil fuels. By converting organic waste into energy, startups can mitigate the problems that come with managing waste while reducing harmful greenhouse gas emissions. These issues help in mitigating some environmental challenges, a very fundamental concern in today’s world. Since governments and international bodies keep calling for clean energy, businesses dealing with renewable energy production are bound to soar in the coming years.

2.      Abundant Raw Materials

The production of CBG from cow dung, Napier grass, and fresh mud is highly feasible due to easy availability of raw materials. For instance, in India, a large cattle population ensures the continued supply of cow dung. There is an immense source of biomass from Napier grass, as it is a fast-growing perennial grass that can be harvested many times in a year. Fresh mud, an easily accessible resource, can be sourced from various agricultural or natural lands. The availability of these raw materials in large quantities at low cost makes this business highly cost-effective for entrepreneurs.

3.      Growing Market Demand

The global demand for cleaner energy is rapidly increasing. Countries are moving towards reducing their carbon footprints and achieving sustainable development goals (SDGs). CBG can be used as fuel in transportation, industrial applications, and power generation, thus providing an energy type for multiple applications. Governments are also encouraging the consumption of biofuels through policies and subsidies, thus furthering the growth of the market. As a case in point is the National Policy of Biofuels by the Indian government, which seeks to promote the production and use of biofuels, leading to the massive market opportunity presented by CBG.

Market Size, Share, and Trends

The size of the global biogas market has exceeded more than USD 60 billion as of 2023. Further, from the period 2024-2030, this market is set to experience compound annual growth of approximately 5.8%. This makes a case for more focus on CBG sector specifically due to a high level of methane, offering potential opportunities as a direct replacement for the widely used fossil-based fuel products in the shape of CNG-Compressed Natural Gas.

India is one of the largest markets for biogas production due to the availability of raw materials and government initiatives for renewable energy. The market share for CBG is likely to increase because the nation has planned to raise its renewable energy capacity to 175 GW by 2025. In this context, the Indian market for CBG is a huge potential for new entrepreneurs and startups to make their mark in the renewable energy sector.

Export Potential

CBG also has vast export potential, especially in countries moving towards greener economies. European countries are interested in reducing carbon emissions and need alternative energy sources like biogas. Indian entrepreneurs and those from other developing countries can exploit this export market by emphasizing quality production and following international standards. Furthermore, the development of biogas-powered automobile markets in the European Union as well as developed countries creates yet another opportunity to export CBG.

Machines Required for Manufacture of CBG

Startups that intend to erect a manufacturing facility for CBG will need:

1. Anaerobic Digester: An anaerobic digester whose process breaks up organic materials by anaerobes to liberate biogas. Examples of organic matter include cow manure and Napier grass.

2. Storage Tanks for Biogas: This is to store the biogas produced in the digesters before compression.

3. Biogas Purification Units: These are important units in purification of biogas. Hydrogen sulfide and carbon dioxide must be removed from the biogas, ensuring a high methane content.

4. Compressor: To compress the purified biogas for storage under pressure as CBG.

5. Gas Analyzers: To check on the quality of the biogas, thus meeting market requirements.

6. Pipeling Network: Pipelines will be used for carrying raw materials inside the plant as well as to transfer biogas to storage or transmission locations.

7. Generators: If the biogas will be utilized for electricity generation, the generators will produce electricity from the energy available in biogas.

Manufacturing Process

1. Scrap Collection: Cow dung, Napier grass, and wet mud are collected from farmlands and agricultural regions.

2. Anaerobic digestions: These feedstock’s are fed into the anaerobic digesters, which consists of microbial breakdown of the organic matter without oxygen. The process produces biogas, mostly consisting of methane and carbon dioxide.

3. Purification: Some impurities, hydrogen sulfide and excess carbon dioxide in the raw biogas, are removed through the purification process to produce high-quality methane gas.

4. Compression: The cleaned biogas is compressed with a compressor and becomes CBG. It is stored in high-pressure cylinders for distribution.

5. Distribution: The final CBG product can be transported and distributed to different sectors such as transportation, industrial use, and household cooking.

Investing in CBG manufacturing from cow dung, Napier grass, and fresh mud offers a sustainable and profitable business opportunity for entrepreneurs. With increasing needs for renewable sources of energy coupled with abundant supply of raw material, this proves to be very feasible. Biogas also offers great entrepreneurship opportunities because its market is widely expanding and various governments offer a lot of incentives to start one’s own businesses, export facilities, and raw materials, therefore, proving profitable as well.
