BioGas and BioLNG Integration
Systems to produce, upgrade, and liquefy biogas from organic waste
Project Overview
Biogas and BioLNG integration systems capture methane from organic waste sources, upgrade it to biomethane, and liquefy it to produce carbon-neutral or carbon-negative LNG. These systems create a circular economy solution that addresses both waste management and clean energy production challenges.

Frequently Asked Questions
What types of feedstock yield the best biogas production?
Feedstocks with high energy content and biodegradability produce the most biogas. Food waste typically yields 100-200 m³ of biogas per ton, while animal manure produces 20-30 m³ per ton. Co-digestion of multiple feedstocks often optimizes both yield and process stability.
How does bioLNG compare to conventional LNG in terms of quality?
When properly upgraded, bioLNG is chemically identical to fossil-derived LNG, with methane content typically exceeding 97%. It can be used in all the same applications and blended with conventional LNG in any proportion.
What happens to the digestate after biogas production?
Digestate is a nutrient-rich by-product that can be separated into liquid and solid fractions. The solid fraction can be composted or directly applied as organic fertilizer, while the liquid fraction can be used for irrigation or further processed to recover nutrients.
How is the carbon-negative status of bioLNG achieved?
Carbon-negative status is achieved when the greenhouse gas emissions avoided (from waste decomposition and fossil fuel displacement) exceed the emissions from the production process. This is typically verified through lifecycle assessment and third-party certification.
