POWERING A SUSTAINABLE FUTURE
our vision
To redefine waste as a resource through the practical application of technology, creating sustainable waste-to-energy solutions.
OUR SOLUTIONS
what we offer
Anaerobic Digestion
Consultancy
We analyze your organic waste profiles to provide accurate data-driven cost and return projections, eliminating guesswork from your investment decisions.
Anaerobic Digester
Design
We engineer bespoke anaerobic digestion systems tailored precisely to your specific waste volumes, space constraints, and operational energy goals.
Engineering and
Contracting
We deliver full-service engineering, procurement, and professional installation to bring your waste-to-energy infrastructure from blueprint to active commission.
Gas Upgrading & CO₂
Capture
We supply advanced membrane and PolyCapture™ systems that efficiently convert raw biogas into high-quality biomethane and biogenic CO₂.
Laboratory Support
Services
Our fully equipped facility provides Biomethane Potential (BMP) testing and comprehensive analysis to continuously monitor your system’s operational health.
Nutrient Recovery &
Soil Conditioning
We extract valuable plant nutrients from digestate, converting residual process streams into high-nutrient soil conditioners and premium vermiculture products.
High Cellulosic Waste
Digestion
Our proprietary Kifaru™ system successfully digests tough, fibrous materials—like cut flowers—using a modular process with low water requirements.
Clean Cooking Gas
Solutions
We install reliable biogas distribution systems that redirect captured gas into kitchens, providing a sustainable, smoke-free alternative for cooking.
Engineered for Efficiency
Our Anaerobic
Digesters
Innovative Anaerobic Digestion Systems for Sustainable Waste-to-Energy Solutions
Standard, one-size-fits-all systems often fail because organic waste varies. We engineer specialized anaerobic digesters tailored to your specific waste profile and operational scale, ensuring maximum biogas yield and high-quality fertilizer with a minimal footprint.
Kifaru™
Our premier high-solids batch system built for tough, fibrous waste like cut flowers. Requires minimal water and low operational energy.
Kiboko™
A heavy-duty, continuous-feed system optimized for high-volume waste processing and maximum biogas yields across large-scale operations.
Kabee™
A compact, highly efficient anaerobic digester engineered specifically for smaller-scale agro-processors and localized waste streams.

Our Story
About US
Founded in 2020, Grants Biotech Ltd specializes in the anaerobic digestion of high cellulosic organic waste, helping businesses transform waste into valuable renewable energy and sustainable resources. Based in Naivasha, Kenya, we have developed innovative solutions that address the unique waste management challenges faced by the cut flower industry and other agro-processors across Sub-Saharan Africa.
Our journey began as part of a collaborative project with the University of South Wales and Qube Renewables, supported by the UK Innovate Programme. Through years of research, development, and refinement, we successfully created a commercially viable high solids anaerobic digestion system capable of processing waste streams that conventional digesters struggle to handle.
Today, Grants Biotech combines advanced technology, scientific expertise, and practical industry experience to.....
