Biocoal Use in Municipality Waste Management

Through the refinement of biomass to biocoal using the CarboREN® process from SunCoal Industries, organic waste loses its „waste“ characteristics and is transformed into a standardized, homogenous biofuel, which can be used in heat and power plants as energy source. This includes, for example, a pellet boiler with a capacity of >100 kW, which can be used for municipal energy needs (indoor heating and warm water supply), where today only wood pellets are used.

The composition and characteristics of biocoal powder are comparable with those of dry brown coal powder. This allows SunCoal® biocoal to be used in existing plant technologies as a substitute for dry brown coal for decentralized pulverized coal firing for electricity or for heat and power generation. The use of biocoal for energy is CO2-neutral, in comparison to fossil coal, which makes this process more environmentally and climate friendly.

Use of biocoal for heat and power generation can also be applied to gasifiers. These produce a fuel gas, which at high electric efficiency can be burned in gas engines for CO2-neutral, continual heat and power generation (CHP).

Additionally, co-firing with biofuel can be considered in power stations that use fossil coal. Since the co-firing of biomass has been initiated in other EU-countries (especially BeNeLux and UK), almost all German power plant operators have considered it as well.
