BioChar- Truly Carbon Negative

Agriculture in India has a significant impact on both its people and the environment.

About 47% of India’s population is dependent on agriculture. It supports their livelihood, ensures food security, and plays a vital role in rural development. It also supports the growth of other industries like textile, food processing, agrochemicals and machinery. The agriculture industry also contributes to about 15% of India’s GDP and export earnings by producing rice, wheat, and spices.

Similarly, agricultural practices can significantly impact the environment. Intensive farming and uncontrolled practices like over-fertilisation and over-irrigation can degrade soil quality, affecting farm productivity and soil’s ability to sequester carbon dioxide. Agricultural runoff containing fertilisers, pesticides, and animal waste can contaminate water bodies, leading to water pollution and eutrophication in severe cases resulting in toxic algal blooms and harm to aquatic ecosystems. Common agricultural practices are also a significant source of greenhouse gas emissions, primarily methane, carbon dioxide, and nitrous oxide. In fact, an article by the World Bank revealed that the global agrifood system emits one-third of all emissions and with the increasing food demand, it is ever more so important to find productive and sustainable solutions.

These activities not only impact agricultural practices and the environment but have a severe impact on people. Those exposed to contaminated drinking water can face severe health risks and the use of such water for irrigation can in turn cause food safety concerns due to the presence of harmful pathogens and chemicals. GHG emissions from agriculture also contribute to climate change, causing severe weather events, health risks, and economic disruptions.

Similarly, every year India witnesses open burning or stubble burning of over 120 million tonnes of rice husk. Northern India, especially suffers due to the resultant smoke causing spikes in the Air Quality Index (AQI) making it difficult to breathe.

In summary, the environmental consequences of agriculture not only directly impact those in the industry, but also the others that are exposed to the repercussions of these activities.

Managing agriculture in India is tricky mainly due to limited resources and a large growing population to feed. This emphasizes the need to increase food production and preserve existing natural resources. However, degraded soil impacts the lives of many communities on a global scale. Asia, Africa and other developing nations face the worst of these consequences and require systematic intervention to enable more efficient and sustainable food production.

Brahmearth aims to reduce the environmental impact of agriculture and improve its productivity with a sustainable solution. During our search, we discovered an age-old process of turning agricultural waste into a soil enhancement- biochar. It offers a promising solution for addressing climate change, improving soil health, and increasing agricultural productivity.

Biochar is known for its ability to sequester carbon from the atmosphere. When biomass is converted into biochar, it locks away carbon that would otherwise be released into the atmosphere as CO2 if the biomass were to decompose or be burned.

But, biochar is primarily used as a soil amendment. When added to soil, it can improve soil fertility, structure, and water retention. Due to its porous structure, biochar acts as a habitat for soil microbes and helps retain moisture and nutrients in the soil, making it more fertile, and resilient, and essentially promoting plant growth.

Biochar has a high surface area and a negative charge, which allows it to attract and retain nutrients in the soil, preventing it from leaching away. This can lead to increased nutrient availability for plants over time while reducing nutrient runoff.

Additionally, it can reduce the need for synthetic fertilisers, which are often produced with high energy inputs and contribute to greenhouse gas emissions.

To facilitate the production of biochar, we developed the Brahm BioReactor. Our iterative research, experimentation, and development led to a multi-purpose pyrolyser that utilises agricultural and forest waste like rice husk and straws, wood chips, and nut shells, treating it at high temperatures in the limited presence of oxygen to create a carbon-rich, porous structure called biochar.

The BioReactor is differentiated by its ability to produce biochar efficiently and adapt to the users’ needs.

Unlike traditional pyrolysers, the BioReactor is portable. It can be mounted at the back of tractors, reducing the time and cost of transportation.

Its internal heating system increases fuel efficiency and provides consistent heating.

It also comes with outlets to extract multiple outputs like biofuel and biogas which can be used as sustainable fuels.

It operates on a continuous spiral feed, eliminating the need for batches, reducing downtime and maximising production efficiency.

The BioReactor is also able to customise biochar with post-production treatments and additives to produce biochar engineered to its usage needs.

The primary audience for biochar is smallholder farmers who own or manage small plots of agricultural land for a livelihood. These farmers play a crucial role in ensuring food security, community growth and rural economic growth, especially in developing countries.

Smallholder farmers contribute to local and regional food production, providing essential sustenance for communities. They create an ecosystem and a foundation that builds communities. By empowering them with resources, knowledge, and support, it is possible to secure the livelihood of many communities.

In India, where agriculture is the primary source of occupation for a significant rural population, the incorporation of sustainable practices at the foundational level can have positive environmental impacts.

For these reasons, small-scale farmers play a crucial role and also hold the power to make change. Most developing countries also recognise and prioritise the empowerment of small-scale farmers by providing financial and market incentives, training and guidance, and creating policies for their protection.

According to India’s Agriculture Census in 2015-16, 86.1 per cent of Indian farmers are small and marginal, which means that they have a landholding size smaller than 2 hectares. The sheer number of farmers makes it challenging to have sufficient access to resources like land, finance, and agricultural equipment. The limited resources then make it harder to keep up the yield and maintain a steady income.

Additionally, climate change has brought unpredictable weather patterns, negatively impacting crop yields. Over the last few decades, extensive farming and controlled practices have also led to severe soil degradation in some regions, resulting in poor plant growth.

Biochar can empower smallholder farmers to secure their livelihoods. It enhances soil fertility by retaining water and nutrients. This increases plant growth and makes them more resilient to climatic changes. The continuous use of biochar can also contribute to restoring degraded soil and increasing agricultural productivity.

Biochar makes efficient use of existing resources like water and fertilisers, reducing the dependency on external resources while improving existing produce. Additionally, due to its carbon sequestration nature and contribution to climate action, biochar will play a crucial role in securing the limited resources for future generations.

By involving smallholder and marginalised farmers in sustainability planning, their needs and perspectives are prioritised. It ensures that their voices are heard, their concerns are addressed, and their rights are respected, contributing to social equity and inclusivity.

As a child, I grew up watching my family work on the farms. Our farm is located in a region with fertile red soil and good rainfall, but over the past few decades, there has been a decline in soil quality which has affected the farm’s productivity. But, I noticed that this trend was not unique to our area. While researching this problem with my team, we realised that productivity was an issue in many regions of India. The main reason behind this was uncontrolled agricultural practices such as excessive fertilisation and irrigation. Over time we realised that many farmers were facing trouble keeping up their produce due to soil degradation or water scarcity, or both.

Another concerning observation we made was the practice of burning crop residues after each harvest cycle, particularly in northern India. This practice not only significantly contributed to the region’s high Air Quality Index (AQI) but also impacted the soil quality. Our conversations with farmers revealed that many of them found burning agricultural waste or stubble burning to be the easiest, cheapest, and quickest way to eliminate waste. But, we realised that by repurposing this waste into biochar, we could not only mitigate CO2 emissions but also aid in soil regeneration.

Our team is both experienced and diverse, coming from various regions of India. This diversity lets us understand the wide range of problems and challenges faced by farmers across India. With the help of our team, we have been able to talk to farmers from various regions in India leading to many discoveries and learnings.

At Brahmearth, our focus is on creating value for small-scale farmers and so we prioritise co-creation and iterative development with them. We are actively involving them in testing and refining our biochar in field trials.

With a track record of building products across diverse industries, we possess the expertise needed to tackle the challenges of merging functionality with sustainability. Additionally, our prior successful launch of a product facilitating smart farm management has provided us with a valuable understanding of farming practices and the requirements of plants and soil. The BioReactor represents a step towards our commitment to fostering a sustainable agricultural ecosystem.

We are currently in the prototyping and testing stage. At this stage of development, we aim to refine and validate the functionality of the BioReactor and its Biochar before transitioning to the pilot stage.

We have successfully designed and constructed the BioReactor. It incorporates a unique internal heating mechanism and continuous spiral feeding system, designed to optimise fuel and time utilisation. By eliminating traditional batch-wise production, our BioReactor minimises downtime between processing cycles and increases operational efficiency. It can currently produce upto 1 ton of BioChar per day.

Additionally, we have filed for a patent for both the design of the BioReactor and its process of converting biomass into biochar.

We are applying to Solve because we recognise the role it can play in helping biochar reach its audience and create an impact. While we have made significant progress in the development of BioReactor and its biochar, we are aware of the challenges that lie in ensuring its reach and adoption.

We need to establish robust channels for delivering biochar to the farmers who stand to benefit from its application. And while biochar holds the potential to empower farmers and enhance soil fertility and crop productivity its efficacy lies in ensuring that farmers have access to the necessary knowledge and resources to utilise it effectively. We want to form strategic partnerships and collaborations with organisations and entities that can facilitate the distribution and adoption of biochar along with farmer education and support.

Moreover, we recognise the broader environmental implications of biochar, particularly in its ability to sequester carbon and restore soil health. Especially due to escalating climate changes and environmental degradation, biochar could be a promising solution for sustainable agriculture and climate action. However, realising this potential requires the engagement of various stakeholders including environmental organisations, policymakers, and climate change advisors. We hope to forge connections with such key stakeholders and create value together.

Biochar presents a promising solution to the productivity challenges in agriculture today. With many farmers and consumers today struggling with the depletion of limited natural resources, it offers a sustainable approach to maximise their efficiency.

Our BioReactor serves as a crucial tool in facilitating the production and utilisation of biochar. Providing farmers with a viable alternative to stubble burning not only prevents carbon dioxide emissions but also mitigates the soil damage inflicted by this harmful practice.

The BioReactor is designed to maximise the efficiency of biochar production. Its portability reduces the logistical burden of transporting raw materials and biochar. Additionally, it integrates sensors to monitor biochar quality and includes provisions for tailored treatment.

Beyond its immediate benefits, biochar serves as a catalyst for raising awareness about the impacts of unsustainable agriculture practices. Shifting the focus towards soil health and enhancement has the potential to influence the shift of agrochemical industries towards sustainability.

Biochar’s carbon sequestration abilities also position itself as a solution for climate change. And, as global sustainability initiatives prioritise carbon neutrality, the demand for carbon-negative solutions will rise, creating new market opportunities in the agricultural sector.

In essence, biochar is not only a practical solution for productivity problems in agriculture but also a catalyst for change towards a sustainable agriculture industry.

Our approach is strategically designed to address the environmental and productivity challenges in agriculture by producing biochar from agricultural waste and utilising it in farming practices.

Inputs include expertise in biochar production and application, agricultural residue for biochar production, The BioReactor to convert biomass into biochar, and partnerships with research institutes, farmers, and agricultural organisations to test and validate the biochar made.

Activities encompass the design and development of the BioReactor, collection and processing of agricultural waste, training and education of farmers on soil quality and biochar usage, and finally the distribution and application of biochar in farming practices.

Outputs consist of biochar produced from diverting agricultural waste from burning, increased adoption of biochar as a soil enhancement among farmers, and elevated soil organic matter content due to biochar application. In fact, there have been several studies that have tested the impact of biochar on soil quality, showcasing its positive impact on soil pH, cation exchange capacity, organic carbon, and microbial diversity.

Expected outcomes include improved soil fertility and structure, enhanced water retention and nutrient availability in soil, increased crop yields and farm productivity, and reduced dependency on chemical fertilisers and agrochemicals.

The long-term impact of our approach results in a reduction in the environmental footprint of agricultural practices, improved livelihoods and income for farmers, contributions to climate change mitigation, and the promotion of regenerative agriculture on a broader scale.

In essence, the adoption of biochar derived from agricultural waste is a promising solution to divert the carbon dioxide released from stubble burning and enhance soil quality, eventually resulting in increased crop yield and fewer greenhouse gas emissions.
