What is BioFlex Engineering?
We develop modular biogas equipment that is portable, affordable, and easy to operate. Our systems help farms and food businesses convert organic waste into renewable energy, without the massive investment of traditional fixed installations.

BioFlex is currently developing modular farm-scale biogas systems for Irish farms. The work below shows the engineering scope, from plant layout to feedstock handling and dosing, being prepared for pilot deployment.
Plant design
Fig. 01
Modular farm-scale biogas plant
A complete farm-scale anaerobic digestion plant designed for Irish dairy and mixed-farm operations. The system integrates the digester tank, gas storage dome, slurry handling, and a containerised control unit into a single compact footprint that fits within standard farm yards. The modular layout allows the plant to be transported, installed, and commissioned with minimal civil works, making biogas production economically accessible to individual farms that the large-scale industry cannot serve.

Feedstock handling
Fig. 02
Two-chamber stainless steel feeding bunker
A custom stainless steel feeding bunker designed for controlled feedstock delivery into an anaerobic digestion line. The two-chamber configuration allows separate handling of different feedstock streams, for example slurry and solid co-substrates, with an integrated drive and discharge system maintaining consistent flow into the digester. Stainless steel construction ensures corrosion resistance, easy cleaning, and long service life in continuous-operation farm environments.

Dosing system

Push-floor dosing and transfer system
A push-floor dosing system designed to deliver controlled, repeatable feedstock doses from the feeding bunker into the digester. The system combines a push-floor discharge mechanism with an inclined screw conveyor and integrated dosing tank, allowing precise feed rate control and consistent digester loading. Designed for retrofit alongside existing concrete digester tanks, with structural framing and access points engineered to suit the operating site.

Design stage

The same system, at design stage
Every installation is resolved as a full layout drawing before anything is fabricated: equipment positions, structural framing, pipe routing, and access points are all fixed against the real site. Working this way means clashes are found on the drawing rather than on the yard, and the customer sees exactly what will be installed before committing to manufacture.

Why choose biogas?
- Lower Energy Costs
- Generate your own heat and electricity from waste you already produce.
- Reduce Waste Disposal Fees
- Turn disposal costs into a productive energy source.
- Generate Additional Income
- Sell excess energy back to the grid for extra revenue.
- Environmentally Friendly
- Cut emissions and contribute to Ireland's renewable targets.
Projected returns for a typical farm
Projected figures for a typical 80-cow Irish dairy farm running a BioFlex unit. Actual results will depend on feedstock, site, and energy prices.
- Renewable Heat / Year
- 60,000 kWh
- Power your dairy parlour, hot water, and heating, straight from your own slurry.
- Premium Bio-Fertiliser
- 1,000 tonnes
- Nutrient-rich digestate replaces costly chemical fertiliser and improves soil health.
- Annual Savings
- €9,000 to 14,000
- Cut energy and fertiliser bills while turning a waste problem into a revenue stream.
- Payback Period
- 5 to 7 Years
- With eligible SEAI SSRH operational support for renewable heat, the investment is projected to pay back within five to seven years.

Our first pilot on a real Irish farm
Our first commercial pilot is being prepared at Saltrock Dairy, a working family farm in Co. Wexford. The Letter of Intent is signed and installation is upcoming.
Saltrock Dairy, Co. Wexford
80-cow dairy farm
Letter of Intent signed. Installation scheduled for Q4 2026, not yet complete. The pilot will validate our system in real Irish farm conditions and serve as a working showcase for future customers.
Become our next pilot farmWhat the pilot delivers
- Converts daily slurry into renewable heat & power
- 30 m³ digester, sized for typical Irish dairy operations
- 25 to 30 m³ of biogas produced per day
- On-site fertiliser to replace chemical inputs
