Envigas Biocarbon
Fossil Free Transition with BioCarbon Solutions
Envigas helps industries reduce carbon emissions using pyrolysis to turn biomass into biocarbon, biooil, and biogas. We focus on the steel sector, replacing fossil fuels and saving 3.3 tonnes of CO₂ per tonne of biocarbon. This cuts emissions and ETS costs. Let’s collaborate for a cost-effective, lower-carbon future.
Sustainable BioCarbon
Envigas builds, owns and operates high-precision, large-scale pyrolysis plants which turn organic residuals into premium quality BioCarbon and energy. Envigas uses residuals from the forestry and wood industry as sawdust, shavings or wooden pellets that can be turned into high-value output.
Learn more about HQ BioCarbon
BioCarbon is a mixture of pure carbon and in-organics from raw material. Along with BioCoke, it can be used as a reduction agent, in skimming and injection for the metallurgic industry, or can be post-processed to bio-based carbon black or bio-graphite.
Our 5 step process secures quality and high carbon content
Feedstock Qualification & Preparation
The choice of residuals as feedstock is of utmost importance for the remaining process steps. Residuals should originate from certified and traceable sources. For the efficacy of the process a low-level humidity is advantageous. We only use residuals from Nordic stemwood, pine or spruce.
Pre-treatment (alternative by choice)
Dependent upon the type of feedstock or biomass, pre-processing treatment can be required. The level of humidity, particle size and shape defines the need for pre-treatment to be optimised for the remaining steps of pyrolysis. As one alternative, wooden pellets could be used with a homogenous shape and particle size, humidity and traceability.
Pyrolysis
The biomass is pyrolysed in a heated and inert (oxygen-free) process of approximately 600°C. The quality of the HQ BioCarbon output is controlled by factors such as temperature and residence time for biomass in process. Approximative yield of biomass to HQ BioCarbon is 20-25%.
Selective Condensation
The process for pyrolysis of biomass emits pyrolysis gas. The approximate biomass-to-gas yield is 60-70%. A selective condensation can be made to output a mix of BioOil and pyrolysis gas. Several post-processing steps can be added to eventually produce e g BioMethane (CH4) or Green Hydrogen (H2). All gas can be condensed to BioOil possible to post-process to fuel-additive quality.
Post Treatment and Packaging
To reduce BioCarbon's high reactivity, there are various means to lower it and make it easier and safer to handle. Envigas has developed several solutions and special routines to secure safe handling and transportation of BioCarbon.
