Our Key Services and Products

Biogas Plant Design and Implementation

We design fully customized biogas plants that efficiently convert organic waste into renewable energy, covering feasibility studies, design, construction, and commissioning for optimal performance and sustainability.

Our designs are built for sustainability: maximizing biogas yield, minimizing greenhouse gas emissions and odours, recovering valuable byproducts such as digestate for use as biofertilizer, and integrating with existing infrastructure where possible. We also offer modular and scalable solutions so plants can grow with the needs of communities, farms, or industrial operations.

Through close collaboration with clients, we adapt to local conditions  feedstock types, climate, resource availability, energy needs  to deliver systems that are robust, low maintenance, and cost-effective. The result: clean energy generation, reduced waste burden, local job creation, and a meaningful contribution toward circular economy and carbon neutrality.

Biogas Cleaning and Power Generation Systems

Our advanced biogas cleaning systems purify raw biogas for power generation, enabling clients to harness clean energy, reduce greenhouse gas emissions, and achieve sustainable power generation. We employ state-of-the-art technologies such as H₂S removal, CO₂ separation, moisture and particulate filtering, and siloxane removal to ensure that the resulting gas meets strict standards for engines, turbines, or grid injection.

By removing corrosive and harmful impurities, our systems extend the lifespan of equipment, improve combustion efficiency, and lower maintenance and downtime costs. Clean, upgraded biogas (or biomethane) can be used for electricity and heat production, transportation fuel, or injected into natural gas pipelines.

Integration with gas storage, pressure regulation, and safety controls ensures safe, reliable operations. Our solution design takes into account local factors: chemical composition of feedstock, ambient conditions, regulatory emissions norms, and customer energy demands.

With our biogas cleaning systems, clients not only get access to renewable energy, but also enjoy cleaner air, compliance with environmental standards, lower operational risk, and more predictable project economics

Biomass Briquetting and Pelleting Plants

We offer biomass briquetting and pelleting plants that convert agricultural residues into high-density fuel pellets and briquettes, providing efficient energy for heating and power, and promoting sustainable energy practices.

Our systems are engineered to ensure:

• Optimized feedstock handling — preprocessing steps like shredding, drying, and grinding to consistently meet moisture, size and purity specifications, ensuring smooth production.

• High output & uniform quality — precision pelletizing and briquetting presses that produce fuels with high density, uniform size and shape for better combustion, easy transport and storage.

• Energy efficiency & minimal losses — we design for low energy consumption in compression & drying, heat recovery, and low dust and ash content to reduce the cost per unit of energy.

• Versatility & modularity — from small-scale units suited for farms or remote communities to large industrial plants; scalable so clients can incrementally increase capacity as demand grows.

• Eco-friendly operation — minimizing emissions, avoiding additives, using renewable energy where possible, and ensuring that waste by-products (like fines or dust) are reused or disposed of in environmentally safe ways.

By supplying reliable briquetting and pelleting solutions, we help our clients:

• Slash costs in fuel procurement, logistics, and storage.

• Reduce their carbon footprint and improve energy security.

• Create new revenue streams by turning low-value biomass into marketable fuel products.

• Support local employment, supply chains, and resilience (especially in rural or off-grid areas).

Efficient Biomass Stoves

Our efficient biomass stoves optimize fuel combustion, reduce emissions, and enhance cooking efficiency, tailored to diverse cooking needs and promoting sustainable energy use. We design them with:

• Improved combustion chambers that increase heat transfer and reduce unburned fuel particles, which means less smoke, lower fuel consumption, and reduced firewood or briquette usage.

• Air-flow control & insulation to ensure stable, clean burn, better safety, faster cooking times, and less heat loss.

• Versatility in fuel compatibility  able to efficiently burn briquettes, pellets, agricultural residues or sustainably sourced biomass  depending on what is locally available.

• Ergonomic and user-centric design so that stoves are user-friendly, safe, easy to maintain and clean, with minimal risk of indoor air pollution.

• Modular sizes for different settings  from household kitchens to community cooking halls, institutions, small restaurants  so that energy efficiency scales as per demand.

• Durability and low maintenance using robust materials and design features that resist wear, corrosion, ash build-up, and harsh environmental conditions.

By using our biomass stoves, customers benefit from lower cooking fuel costs, healthier indoor air quality due to lower smoke and particulate output, and a move towards cleaner, renewable fuel sources. These stoves are a practical tool in our mission to support sustainable energy in households, communities, and regions where traditional cooking methods carry high environmental or health costs.

Biogas Digesters and Storage Solutions

We provide prefabricated biogas digesters, including floating and fixed domes, as well as biogas storage balloons, designed for durability and efficiency, ensuring reliable biogas storage and utilization. Our digesters are pre-fabricated in controlled environments to ensure precision, robust sealing, and consistent material quality, which minimizes on-site construction time and helps avoid typical issues like crack formation or gas leakage.

• Fixed-dome digesters come as single rigid chambers with integrated gas domes. Built underground, they are protected from temperature swings, have no moving parts, resist corrosion, and offer long lifetimes (often 20+ years) when well constructed.

• Floating-dome designs (or floating gas holders) use a gas collection dome or drum that rises and falls with gas production. This gives more stable gas pressure, better visual feedback of gas volume, and easier management for applications needing steadier output.

• Prefabricated balloons / gas storage balloons are lighter, flexible gas storage solutions suited for modular or temporary set-ups, or for storing surplus biogas where fixed/inflexible storage is impractical. These also allow for rapid deployment and are useful in remote or decentralized settings.

Our designs focus on:

• Gas tightness and sealing, using modern sealants, coatings or composites to prevent losses and ensure safety.

• Material selection and build quality (concrete, ferrocement, fiberglass, steel or composite where appropriate) to resist corrosion, temperature stress, moisture and mechanical wear.

• Safety and regulation compliance, with pressure relief, overpressure protection, flame arrestors, gas outlet controls, and safe pipelines.

• Integration with gas cleaning and utilization systems: because the quality of the stored biogas (in terms of moisture, H₂S, CO₂ content, etc.) affects what you can do with it (e.g. engine-driven generators, boilers, or injection), our digesters are designed with accessories or downstream compatibility in mind.

• Ease of maintenance: access hatches, cleaning ports, inspection windows; modular prefabricated components help with repair or replacement.

• Adaptable sizing and modularity, so clients can choose digesters and storage capacities suited to their feedstock volume, gas demand, and expansion plans.

Benefits & Why It Matters

• Reliable gas storage ensures that biogas generated is not wasted, improving overall system efficiency and return on investment.

• Stable pressure and good storage help downstream appliances or generators work more reliably, reducing wear and tear.

• Better sealing and materials reduce emissions of methane, a potent greenhouse gas.

• Prefabrication reduces construction risk, reduces time onsite, and often reduces cost versus traditional fully onsite masonry builds.

• Flexibility (fixed, floating, or balloon) allows solutions optimized for different use-cases: farms vs industrial vs community; cold climates vs hot; high feedstock vs low; permanent vs mobile setups.

Biogas Scrubbing Systems and Engines

Our biogas scrubbing systems remove impurities from biogas, enhancing its quality for various applications. We also offer biogas engines that convert purified biogas into electricity and heat, supporting sustainable energy generation.

Once purified, this upgraded biogas becomes a high-quality fuel source. Our biogas engines are designed to convert the cleaned gas into electricity and heat through combined heat & power (CHP) units. This means users can generate power for their operations or feed into the grid, while also utilizing waste heat for heating, drying or other process requirements  improving overall energy efficiency.

What sets our solutions apart:

• Higher methane content / increased energy output — by removing CO₂ and other diluting or inert gases, the gas’s combustion value rises, delivering more power per unit volume.

• Equipment protection & lower maintenance costs — H₂S is corrosive, moisture causes rust & mechanical issues, siloxanes leave silica deposits; our scrubbing protects engines, turbines, valves and pipelines, extending equipment life.

• Environmental compliance & reduced emissions — cleaner gas means fewer pollutants in exhaust (sulfur oxides, particulates), better compliance with emissions regulations, and lower greenhouse gas leakage.

• Stable & efficient engine performance — engines run smoother when fed clean, dry, high-methane biogas. This means better output, more predictable operations, less downtime, and optimized fuel usage.

• By-product recovery — some scrubbers allow capture or transformation of waste streams (e.g. elemental sulfur, filtered solids) that can be used or sold, improving overall economics.

Typical features and design considerations:

• Scrubber systems sized and customized for flow rate, impurity levels, operational load, and local environmental conditions.

• Multi-stage purification: e.g. moisture removal –> H₂S removal –> CO₂ or other gas separation –> polishing filters.

• Gas storage, regulation, safety components (pressure relief, flame arrestors etc.) integrated with scrubbers and engines.

• Monitoring & control systems for gas quality (H₂S content, CH₄ concentration, moisture) so operations can be adjusted in real time.

Benefits our clients enjoy:

• Reduced fuel and operational costs thanks to higher efficiency and less engine wear.

• Greater reliability & uptime for power generation and heat production.

• Stronger sustainability credentials: lower emissions, safer operations, better resource utilization.

• Flexibility to use biogas in a variety of applications  electricity generation, heating, industrial processes, or even for upgrading to biomethane for injection or vehicle fuel.

Biomass Briquettes and Pellets

We produce biomass briquettes and pellets from agro-forestry waste, offering a renewable and efficient alternative to conventional fossil fuels, known for high calorific value and minimal emissions.

What Makes Our Briquettes and Pellets Great:

• High energy output: With optimized densification and low moisture content, our fuels deliver high heat per kilogram (often in the range of 3,500–4,800 kcal/kg depending on the feedstock), helping reduce fuel consumption for the same energy requirement.

• Low ash and low residue: High quality briquettes/pellets leave behind much less ash compared to coal or firewood  fewer disposal problems, cleaner combustion, and less maintenance of boilers or stoves.

• Uniform size and consistency: The material shape, density, size, and moisture are controlled for better combustion efficiency, predictable performance, and ease of handling (storage, transport, feeding into burners or boilers).

• Lower emissions & environmental impact:

  • Carbon-neutral fuel cycle: the CO₂ released during burning is roughly equal to the CO₂ the plants absorbed during growth.

  • Significantly lower emissions of sulfur, nitrogen oxides, particulate matter, and smoke compared with fossil fuels like coal or fuel oil.

  • Reduction in deforestation pressure (using waste instead of sourcing new wood) and supporting cleaner air outcomes, especially critical in industrial or population dense zones.

Key Advantages & Use Cases:

• Cost effectiveness: Because agro-waste is often low cost or even waste by-product, converting it to briquettes/pellets delivers fuel that can be cheaper than fossil alternatives (coal, furnace oil, etc.), especially when transport, handling, and disposal costs of ash are included.

• Versatility: Suitable for many applications  industrial boilers, process heating, thermal power plants, drying, cooking, small-scale heating or cooking stoves. Can often be retrofitted into existing setups.

• Improved logistics: Briquettes and pellets are compact, dense, uniform  easier to store, transport, automate feeding, and handle compared to loose biomass or bulky waste.

• Supports circular economy & rural livelihoods: By valorizing agricultural & forestry waste, we reduce pollution from waste burning or decomposition, create new income sources for farmers and biomass collectors, and foster local employment.
