Biowaste2Gas provides a patented three‑stage gasification system that converts dewatered sludge, ash‑rich fibers, and other biomass residues into low‑tar synthesis gas and a phosphorus‑rich biocoal. The syngas can feed gas engines for combined heat‑and‑power or be upgraded to synthetic fuels, while the biocoal serves as a fertilizer, reducing disposal costs and emissions for wastewater and biogas plant operators.

Problem
Municipal wastewater treatment plants and biogas facilities generate large quantities of dewatered sludge, ash‑rich fiber fractions, and other residual biomass that are costly to dispose of and contain untapped energy and phosphorus resources.
Solution
Biowaste2Gas offers a patented “Kombi‑forgasser” that thermally converts these waste streams into tar‑free synthesis gas and a phosphorus‑rich biocoal. The system employs a three‑stage architecture: a pyrolysis zone that eliminates contaminants such as micro‑plastics and heavy metals, a water‑gas‑shift reactor that maximizes combustible gas yield, and a short‑duration high‑temperature (900‑1100 °C) tar cracking stage that ensures the syngas meets low‑tar specifications. The resulting syngas can be fed directly to gas engines for combined heat‑and‑power generation or upgraded to synthetic fuels, while the solid biocoal retains plant‑available phosphorus for use as a fertilizer or further processing. The technology integrates an in‑line gas centrifuge and self‑cleaning filtration to remove residual tars, water, and particulates, enabling continuous operation with minimal maintenance. By valorizing both the energy and nutrient content of waste streams, the solution lowers disposal costs, reduces greenhouse‑gas emissions, and supports a circular bio‑economy.
Target Audience
Primary customers are operators of municipal wastewater treatment plants and biogas facilities seeking to convert sludge and fiber residues into usable energy and fertilizer products, as well as industrial biomass processors aiming to integrate low‑tar syngas generation into their value chain.
