As industries transition toward climate neutrality, many are seeking solutions that maximize the value of existing resources while aligning with long-term sustainability goals. BioShare recently led an enhanced feasibility study for a major pulp and paper mill exploring the production of liquefied biogas (LBG) from internally generated residual biomass—positioning the site to become a key producer of renewable fuels.
The study focused on integrating thermochemical conversion with liquefaction technology to produce LBG from forest-based residues, a resource already available within the operational boundary of the mill. The concept builds on BioShare’s core competence in gasification system design, energy integration, and industrial decarbonization, and was customized to fit the specific infrastructure, energy demands, and by-product flows at the site.
To deliver a comprehensive decision-making foundation, the study covered four key domains:
- Technical Process Design
We developed a full-scale process concept, from biomass preparation and gasification to syngas cleaning, biogas upgrading, and final cryogenic liquefaction. Mass and energy balances were modeled to simulate year-round operation, taking seasonal variations and load profiles into account. - Site Logistics and Location Optimization
Internal handling and transport of biomass, bed material, and by-products were mapped in detail to evaluate logistical efficiency and operator safety. The study also assessed multiple siting alternatives for the new LBG facility within the industrial footprint, with respect to utility availability, integration potential, and reducing interference with ongoing operations. - Energy and Infrastructure Integration
BioShare explored how surplus process steam, condensate loops, and existing feedwater systems could be leveraged to support the LBG plant without adding strain to the core mill operation. Synergies with flue gas condensation and potential use of waste heat were evaluated to improve overall efficiency. - Project Economics and Business Case
A robust CAPEX and OPEX assessment was conducted, covering all major equipment, civil works, utilities, and operational staffing. We provided a dynamic financial model allowing sensitivity analysis based on LBG pricing, green incentives, and carbon abatement value. The result gave the customer a good understanding of the project economic viability.
