Biodigesters
Cut emissions. Slash costs. Close the loop.
W8ST is the exclusive manufacturer and distributor in Australia and New Zealand of the award-winning SEAB Energy compact biodigesters.
This is technology that’s transforming the way we deal with organic waste—right where it’s created. Whether you're in food production, transport, mining operations, retail or municipal services, this on-site solution turns food and organic waste into clean energy and organic fertiliser in real time.
-
Using a patented dry fermentation process, SEAB’s low-maintenance biodigesters break down organic waste in a sealed, odour-free environment. Advanced monitoring systems ensure optimal microbial activity, producing methane that’s converted into biogas—powering heat and electricity production, or stored for on-demand use.
-
Forget waste transportation, landfill emissions, polluted waterways and missed opportunities. This is decentralised, low-carbon infrastructure built for the future of sustainable business.

Wastewater Heat Recovery
Cut emissions. Reclaim energy. Build circular.
The RecovrE by W8ST is an Australian-made system that captures heat from wastewater and transforms it into clean, low-carbon heating and cooling.
Ideal for buildings and precincts, it turns a constant, wasted energy source into a powerful tool for cutting emissions and boosting circular, sustainable infrastructure.
-
Every day, buildings and businesses send warm water down the drain. The RecovrE intercepts this flow, extracting its thermal energy using high-efficiency heat exchangers and delivering the energy to heat pumps. It is returned as usable energy to your building or precinct.
-
Wastewater is a constant, renewable source of energy that exists in every building. RecovrE turns an overlooked resource into a reliable and sustainable utility.

Algal Biotech
Capture carbon. Create value. Breathe easy.
Pure Biomass Algae Pods use the natural power of microalgae to absorb CO₂ and other pollutants while producing high-value biomass for reuse.
These modular bioreactors bring industrial-strength carbon capture and clean air tech to any site, big or small.
-
Each closed-loop pod circulates water and CO₂ through W8ST’s proprietary live microalgae cultures. As the algae grow, they draw down carbon and produce oxygen—just like a plant, but up to 400x more efficient per square metre. The harvested algae can be turned into nutraceuticals, fertiliser or feedstock, biofuel or bioplastics.
-
In a world of unarrested emissions, this is carbon capture you can see—and scale.

Plastic Waste to Green Energy
Turn your waste plastics into power, not pollution.
Alkany + W8ST: A breakthrough in circular energy infrastructure.
Alkany is W8ST’s solution for one of the hardest-to-solve challenges in waste management: contaminated plastics. Using a patented process that breaks down mixed and soiled plastic waste—including packaging, films and microplastics—Alkany turns plastic into a clean, powerful input for anaerobic digestion and energy recovery.
-
Plastics are shredded, sorted and treated with Alkany’s proprietary biological catalysts and retention process. Once conditioned, these treated plastics are sent into W8ST's containerised biodigesters, where they’re processed alongside organic waste to generate high-methane biogas, liquid and solid digestate and renewable energy. The process is exothermic and self-sustaining, requiring no external energy to operate—making it a low-cost, high-yield upgrade to standard anaerobic biodigester systems.
-
Only 9% of plastic waste is currently recycled in Australia, and most contaminated or composite plastics end up in landfill or incineration. Alkany offers a game-changing pathway to recover value from what would otherwise be a liability—helping businesses and councils meet landfill diversion targets, reduce emissions and generate clean energy on site.
