While exploring the broader social dimensions of biocharBiochar is a carbon-rich material created from biomass decomposition in low-oxygen conditions. It has important applications in environmental remediation, soil improvement, agriculture, carbon sequestration, energy storage, and sustainable materials, promoting efficiency and reducing waste in various contexts while addressing climate change challenges. More, I recently came across an interesting study from Kenya by Gitau, Mendum and Njenga on gender and biochar-producing gasifier stoves. What stayed with me was not only the technology, but the way the study looked at women as knowledgeable participants whose experiences could influence technology development. It prompted me to think about biochar from another perspective: what opportunities can the growing biochar sector create for women—not simply as users or beneficiaries, but as researchers, farmers, entrepreneurs, technicians and decision-makers?

Rethinking the Role of Women in Biochar

Biochar is increasingly discussed in relation to soil management, carbon sequestration, waste valorization, renewable energy and the circular bioeconomy. Yet discussions about the technology often remain focused on its technical characteristics: feedstockFeedstock refers to the raw organic material used to produce biochar. This can include a wide range of materials, such as wood chips, agricultural residues, and animal manure. More selection, pyrolysisPyrolysis is a thermochemical process that converts waste biomass into bio-char, bio-oil, and pyro-gas. It offers significant advantages in waste valorization, turning low-value materials into economically valuable resources. Its versatility allows for tailored products based on operational conditions, presenting itself as a cost-effective and efficient More temperature, carbon stability, surface area, nutrient retention or greenhouse-gas mitigation. An equally important question is how biochar systems interact with the people who produce, use and manage them. For women, particularly in rural and agricultural communities, biochar can intersect with everyday activities such as cooking, biomassBiomass is a complex biological organic or non-organic solid product derived from living or recently living organism and available naturally. Various types of wastes such as animal manure, waste paper, sludge and many industrial wastes are also treated as biomass because like natural biomass these More collection, farming, household energy management and small-scale enterprise. These intersections do not automatically translate into empowerment. Rather, they create opportunities that depend on whether women have access to technology, skills, finance, markets and decision-making spaces.

A useful lesson comes from work on biochar-producing gasifier stoves in Kenya. The research deliberately approached women not simply as beneficiaries of an improved technology but as knowledgeable users whose experiences should influence technology development. The study noted that externally designed interventions can fail when they do not sufficiently consider the priorities and preferences of the people expected to use them. It therefore emphasized involving women in problem identification, technology development and evaluation.This perspective is important for the wider biochar sector. If women are considered only at the final stage of technology deployment, opportunities for meaningful participation may be missed. If they are involved earlier—as researchers, entrepreneurs, producers, farmers, technicians, community leaders and decision-makers—the social and economic dimensions of biochar can become part of the system design itself.

Biochar at the Intersection of Energy, Agriculture and Livelihoods

One reason biochar has relevance to women’s empowerment is its connection with biomass. In many communities, women have historically been closely involved in collecting, preparing and using biomass for household energy. This can involve substantial demands on time and physical labour. The Kenyan case study reported that improved gasifier systems reduced fuel consumption and consequently reduced the need for firewood collection, creating potential time and cost savings for women.

The significance of such changes should not be overstated. Saving time does not automatically result in empowerment. What matters is what women are able to do with the time and resources that become available. Time saved from fuel collection could potentially be redirected towards farming, education, paid employment, community activities, childcare or enterprise. The outcome will depend on the social and economic circumstances of each household.

This is why the empowerment dimension of biochar needs to move beyond the simple idea that a technology “helps women.” The more relevant question is whether women gain greater control over resources, knowledge, income, technology choices and decisions affecting their livelihoods.

From End Users to Technology Designers

One of the strongest lessons from the Kenyan experience is the value of participation in technology development. Women who used the cooking systems were involved in participatory testing, and their feedback contributed to modifications in the subsequent gasifier design. The redesigned system incorporated features responding to constraints identified by women users, demonstrating why their experiences matter during technology development rather than only after a product has been completed. This principle can be applied much more broadly across the biochar sector.

When developing small-scale pyrolysis systems, biochar-producing stoves, biomass processing equipment or farm-level applications, women should be involved in identifying operational requirements and evaluating usability. Their participation can help researchers understand questions that laboratory testing alone may not capture: How much labour is required to prepare feedstock? Is the equipment physically manageable? Can it be repaired locally? Does its operation fit existing household routines? Is the technology affordable? Can the resulting biochar be stored, transported and used conveniently?

These are not secondary questions. They influence adoption. The Kenyan research found that decisions around cooking technologies were shaped by several practical considerations, including fuel availability, labour requirements, household economics and possible income-generating opportunities. The researchers consequently argued for more nuanced consultation with biomass users rather than assuming that users would automatically adopt a technology simply because it was environmentally preferable. The lesson for biochar is straightforward: technical performance and user relevance need to develop together.

Creating Economic Opportunities Around Biochar

Biochar systems can also create opportunities beyond direct agricultural application. Feedstock preparation, biomass collection, equipment operation, biochar production, quality assessment, packaging, distribution and application all represent potential points of economic activity.

The Kenyan case study identified opportunities for women to provide services associated with biomass preparation and to sell surplus charcoalCharcoal is a black, brittle, and porous material produced by heating wood or other organic substances in a low-oxygen environment. It is primarily used as a fuel source for cooking and heating.   More or biochar. It also reported examples where women could benefit financially from activities connected with fuel and biochar production. Such opportunities should, however, be approached realistically. A technology does not create an enterprise simply because a market theoretically exists. Women need access to finance, equipment, training, reliable feedstock, customers and appropriate regulatory support. They also need sufficient control over the income generated.

This distinction matters because unpaid labour can easily be described as “participation” when it does not generate greater economic agency. A genuinely empowering biochar enterprise should consider whether women are receiving payment, owning equipment or businesses, participating in pricing decisions, accessing markets and retaining a meaningful share of the value created. Biochar therefore has potential as part of a broader livelihood strategy, but realizing that potential requires attention to the entire value chain.

Knowledge Is an Important Form of Empowerment

Another important dimension is knowledge.

Biochar production is sometimes presented as a highly technical field reserved for engineers, scientists and industrial operators. Yet the practical knowledge of farmers and biomass users can be equally important. The Kenyan study explicitly challenged assumptions that women using traditional biomass technologies lacked knowledge, instead recognizing household cooks as experts in managing household energy and food security within their particular circumstances.

This has implications for biochar research and extension. Women farmers may have detailed knowledge of crop residues, seasonal biomass availability, soil conditions, crop performance and household resource constraints. Incorporating this knowledge into research can improve the relevance of biochar interventions while also giving women greater visibility as knowledge holders.

Training can further strengthen this role. Women can be trained not only to apply biochar but also to understand feedstock selection, pyrolysis conditionsThe conditions under which pyrolysis takes place, such as temperature, heating rate, and residence time, can significantly affect the properties of the biochar produced.   More, biochar quality, safe handling, application rates and basic monitoring. In suitable contexts, they can become trainers themselves. The Kenyan study specifically recommended using women who were familiar with the technology and cooking requirements to train other women, rather than relying exclusively on external trainers. That is an important shift: from training women to use technology toward enabling women to teach, adapt and improve it.

Women and the Biochar Value Chain

The future of biochar should not be viewed only through the lens of individual applications. It is developing into a broader value chain involving biomass suppliers, technology manufacturers, researchers, farmers, carbon markets, environmental services and end users. Women can participate at many points along this chain. They can contribute to feedstock management, operate decentralized production units, conduct field demonstrations, manage farmer networks, undertake quality-control activities, develop biochar-based agricultural products and participate in research and consultancy. In urban and industrial contexts, opportunities may also emerge around organic-waste management, biomass processing and environmental services.

Participation across the value chain is important because empowerment is partly determined by where value is captured. If women remain concentrated in low-paid or unpaid labour while ownership and decision-making remain elsewhere, the presence of women in the sector does not necessarily represent meaningful empowerment.

A stronger approach would seek to increase women’s participation in skilled, technical and managerial positions alongside entrepreneurship and community-level activities.

Designing Biochar Programmes With Women, Not Just for Women

The Kenyan experience also demonstrates that affordability and accessibility cannot be separated from technology adoption. In the gasifier case, the cost of the equipment was identified as a significant barrier for women with limited incomes. Suggested responses included local manufacturing, training local artisans, collective savings and institutional support to reduce costs.

Similar questions should be asked when developing biochar technologies. Can equipment be manufactured or maintained locally? Can women access financing? Can producer groups share equipment? Can cooperatives aggregate biomass and market biochar? Can training programmes be structured around women’s existing schedules and responsibilities? Can technology developers incorporate women’s feedback before commercial deployment? These questions turn empowerment from a general aspiration into something that can be considered during project design.

Beyond Symbolic Inclusion

There is also a need for caution. Women should not be treated as a homogeneous group, and biochar interventions that work in one region may not produce the same outcomes elsewhere. Age, income, education, land ownership, household responsibilities, access to markets and local cultural practices can all influence participation.

The Kenyan study itself found differences between younger and older women in their willingness and ability to adopt the gasifier technology, illustrating that gender alone does not explain technology choices. Consequently, biochar projects should avoid assuming that simply including women in a training session or community meeting constitutes empowerment. Meaningful participation requires opportunities to influence decisions, acquire technical skills, access resources and benefit economically from the activities in which women participate.

Building a More Inclusive Biochar Sector

Biochar sits at an interesting intersection of environmental management and rural development. Its value is often measured in tonnes of carbon, crop productivity, energy recovered or waste diverted. Those indicators are important, but they do not capture the full social dimension of a biochar system. For women, the more meaningful indicators may also include time saved, technical skills acquired, income generated, businesses established, participation in decision-making and access to productive resources.

The experience of biochar-producing cooking systems in Kenya offers a useful starting point. It demonstrates that women’s practical knowledge can improve technology design, that reduced fuel requirements can alter household workloads, and that biochar and biomass systems can create small-scale economic opportunities.

The broader message for the biochar sector is not that biochar will automatically empower women. It is that biochar projects can be designed in ways that create more space for women’s participation, knowledge and economic agency. As the sector moves from research laboratories toward farms, communities, industries and commercial markets, that distinction becomes increasingly important. A mature biochar industry should ask not only whether a technology works, but also who develops it, who operates it, who owns it, who benefits from it and whose knowledge shapes its evolution.

Women should not simply be regarded as beneficiaries of the biochar economy. They can be researchers, engineers, farmers, entrepreneurs, technicians, educators, producers and decision-makers within it. Creating those pathways requires deliberate design, investment and participation. That is where the connection between biochar and empowerment becomes meaningful: not through broad claims about technology transforming women’s lives, but through practical opportunities for women to have greater influence over the technologies, resources and economic activities connected to the biochar value chain.
