Who Are We?
We make high strength organic waste management commercially viable and environmentally sound. We secure renewable energy supply, remove cost, lower emissions and return valuable nutrients to the primary sector growers.
We assure this by making sure we:
- Use proven technology – avoids the mystery of custom built solutions
- Design for optimal economic size – bigger is not better
- Are accountable for the supply chain – we can own, operate, manage, report, comply
- Deliver an affordable, workable solution meeting the needs of industry and regulators
- Can scale from single factory to urban waste management

Our History
Bioceta Ltd. is a clean-tech company specialising in the areas of anaerobic digestion (AD), industrial wastewater treatment and bioenergy.
Bioceta’s strategic focus is the design, build and operation of closed-loop anaerobic digestion waste treatment and recycling systems (including biogas energy use) using core technology sourced from Lipp GmbH in Germany.
Bioceta’s solution can address several immediate environmental issues by creating a utility, or customer-owned, plant for high-strength organic waste management and harvesting valuable nutrients from that waste. We can provide capacity expansion for existing wastewater treatment plants and generate consistent green energy in the form of process heat or steam from injection to boilers, conversion to electricity or conversion to vehicle fuel. An additional benefit is a substantial offset of greenhouse gases by reducing landfill and wastewater irrigation volumes that assists in meeting a significant strategic and contractual challenge for many industry sectors.
