Kenyan industrial energy company Lean Energy Solutions has secured B Corp Certification after demonstrating measurable environmental and social impact through its renewable biomass energy model for manufacturers.
The Nairobi-based company has been recognised for helping manufacturers in East Africa shift away from imported fossil fuels to locally sourced renewable biomass, while reducing industrial emissions, energy costs and exposure to foreign-exchange volatility.
The certification comes as manufacturers face increasing pressure to lower their carbon footprint while maintaining reliable and affordable thermal energy for production.
Lean Energy uses a Build-Own-Operate model through which it finances, installs, operates and maintains renewable biomass boiler systems for industrial customers.
Under the model, manufacturers pay for the steam they consume instead of making upfront investments in boiler infrastructure or taking on the responsibility of operating and maintaining the systems.
The company also manages the biomass supply chain, converting agricultural residues such as maize cobs and coffee husks into industrial fuel.
This approach provides an alternative use for agricultural waste while creating local value chains and reducing reliance on imported fossil fuels.
According to the company’s impact data, Lean Energy has reduced emissions by 350,000 tonnes and generated four million person-days of employment.
The company also estimates that its operations have generated US$50 million in foreign-exchange savings for Kenya by reducing dependence on imported fuels.
Lean Energy currently operates more than 20 boiler sites across Kenya and Tanzania, with a combined steam-generation capacity of 90 tonnes per hour.
Lean Energy surpasses B Corp threshold
The certification was awarded after Lean Energy scored 87.5 points in B Lab’s B Impact Assessment, exceeding the 80-point threshold required for B Corp Certification.
The assessment evaluates a company’s impact beyond its products and services, including governance, workers, communities, customers and environmental performance.
Elizabeth Mutwiri, Communications and Engagement Senior Associate at B Lab Africa, said the assessment provided a comprehensive review of Lean Energy’s business practices and impact.
She said the certification demonstrates that responsible business practices can be integrated into how an industrial company operates, competes and grows.
The certification therefore places Lean Energy among businesses seeking to demonstrate that commercial growth can be aligned with measurable environmental and social outcomes.
Biomass provides alternative to imported fuels
Lean Energy Founder and Managing Director Dinesh Tembhekar said the certification reinforces the company’s ambition to support industrialisation in Africa while improving environmental sustainability.
“Africa’s industrial growth should not come at the expense of competitiveness or the environment,” Tembhekar said.
He said the certification would strengthen the company’s ambition to scale a model that provides manufacturers with reliable, lower-carbon energy while building local value chains and reducing dependence on imported fuels.
The company’s use of agricultural residues also creates an opportunity to convert materials that could otherwise go to waste into productive industrial energy.
For manufacturers, the Build-Own-Operate approach removes the need for significant upfront capital expenditure on renewable thermal energy infrastructure, potentially making the transition to cleaner energy more accessible.
Next phase targets expansion
The B Corp Certification marks a new phase in Lean Energy’s growth as it seeks to expand its locally powered energy model across African manufacturing markets.
The company aims to scale a commercially viable renewable thermal energy model that supports industrial competitiveness while reducing emissions and strengthening local economies.
With operations already spanning Kenya and Tanzania, Lean Energy is positioning biomass energy as a practical solution for industries that require reliable thermal energy and are seeking alternatives to imported fossil fuels.
As African countries pursue industrial growth alongside climate and energy-transition goals, Lean Energy’s model highlights the potential for locally sourced renewable energy to reduce industrial emissions while creating economic value within local supply chains.
