Waste never leaves the loop.
Every ReTap plant is built around one idea: nothing organic should be single-use. Waste is collected, digested, purified into energy, put to work, and returned to the soil — then the loop begins again.
- Collect — organic waste is sourced from farms, kitchens & municipalities.
- Digest — anaerobic digestion breaks it down and captures biogas.
- Purify — our patented second-stage system upgrades biogas to >95% pure BioCNG.
- Reuse — the clean fuel powers transport, kitchens, boilers & generators.
- Return — digestate goes back to the land as organic manure.
One clean fuel,
four ways to use it.

Trusted by the people who run our plants.
Our diesel bill dropped within months of switching to ReTap's BioCNG system. The training they gave our staff meant we never once needed an emergency call-out.
What impressed us most was the monitoring — problems were flagged and fixed before we even noticed a dip in gas output.
From the first site visit to commissioning, ReTap handled everything. Our kitchen has run entirely on BioCNG for over a year now.
