Waste to Energy
Turning Organic Waste into Renewable Energy
Our Waste-to-Energy solutions are designed to help businesses reduce waste disposal costs, lower carbon emissions, and generate sustainable energy. By harnessing advanced anaerobic digestion and biogas recovery technologies, we enable industries to convert organic waste into methane-rich biogas, which can be used for electricity generation and heat production or even upgraded to biomethane for grid injection.
Our waste-to-energy solutions are ideal for a wide range of sectors, including:
- Municipal Waste Management (organic household waste, sludge from wastewater plants)
- Agriculture & Livestock (manure, crop residues, food waste)
- Food & Beverage Processing (dairy, breweries, meat processing, sugar mills)
- Industrial & Manufacturing (paper mills, chemical processing, bio-based industries)
By leveraging anaerobic digestion and biogas recovery, businesses can turn organic waste into an asset—supporting energy independence, sustainability goals, and operational efficiency.
Hydroflux Epco & AAT Biogas: A Global Partnership for Sustainable Energy
Hydroflux Epco offers complete, end-to-end anaerobic digestion and biogas solutions for the treatment of organic waste. Through our exclusive partnership with AAT Biogas, an international leader with over 30 years of experience and more than 100 biogas plants operating globally, we deliver proven, high-performance technology tailored to local conditions across Australia, New Zealand and the Pacific.
With deep expertise in handling a wide range of organic waste streams, Hydroflux provides reliable and efficient complete waste-to-energy systems that support energy recovery, emissions reduction and circular economy outcomes.
What Hydroflux Epco Supplies
Hydroflux Epco supplies complete turnkey waste-to-energy systems, including the waste reception systems, pretreatment, anaerobic digesters, biogas handling, energy reuse and digestate treatment.
Waste Reception and Pre-Treatment
Hydroflux Epco supplies and integrates the full range of pre-treatment systems required to condition organic waste for digestion. This includes reception facilities, screening, dewatering, thermal pre-treatment or hydrolysis—tailored to the specific waste type and project scale.
Anaerobic Digestion Systems
Hydroflux Epco provides high-performance anaerobic digesters using AAT’s proven reactor technology. These systems operate under optimised conditions to convert organic matter into biogas, enabling the efficient breakdown of complex waste streams in a controlled, low-oxygen environment.
Biogas Handling and Energy Recovery
Hydroflux Epco supplies and installs all associated biogas systems, including:
- Desulphurisation systems and biogas treatment
- Combined Heat and Power (CHP) units for electricity and thermal energy
- Biogas upgrading systems for grid injection (biomethane)
- Systems for Bio-CNG or Bio-LNG production for vehicle fuel
- Gas storage, flare and safety systems
Digestate Management and Resource Recovery
Hydroflux Epco provides equipment and processes to manage the digestate byproduct. Solutions include:
- Digestate dewatering and drying systems
- Stabilisation and odour control
- Biosolids treatment for agricultural reuse or safe disposal
Different Substrates Require Different Digester Technology.
AAT Biogas designs a range of advanced anaerobic digesters, each suited to specific waste streams to maximise biogas yield and energy recovery. Options include low-profile digesters for buffering and hydrolysis, high-solids systems like hydraulic and CSTR digesters for sludge and food waste, and specialised units such as the MSB for high-fat wastewater and UASB for low-solids industrial effluent.
These technologies enable Hydroflux Epco to deliver tailored waste-to-energy solutions that reduce waste, generate renewable energy and support sustainability outcomes.
| Digester Type | Common Use |
| Flat (Low profile) Digester | 1st stage digesters for buffering and hydrolysing AD of agricultural waste and plants AD with integrated gas storage |
| Hydraulic Digester (without mechanical mixer) | Sewage plants, food waste, sludges from industrial water treatment and other high solids applications |
| CSTR Digester with central agitator | Sewage plants, food waste, sludges from industrial water treatment and other high solids applications |
| MSB Digester | Whey plants and wastewater with high fractions of suspended matter and also high fat contents |
| UASB Digester | High strength wastewater with the low solids content in applications such as breweries, beverage, dairy and paper |
This diagram is an example of a flat, low-profile digester, which is just one of the many Hydroflux Epco can provide. Some of the key features of this arrangement include:
- Digester dimensions: low height/diameter ratio
- Construction: steel reinforces concrete floor, walls and ceilings with center column
- Agitation: vertical shaft mixer combined with submersible mixer
- Feeding system: dry material feeder
- Heating: heating coils inside digester
- Desulphurisation: integrated in digester or external biological desulphurisation
