Biogas production is booming—global capacity reached 110 TWh in 2025 (IEA, Gas Market Report 2025), but 60% of plants struggle with upgrading efficiency. Here’s what’s costing you time and money:
European biogasaufbereitung systems often exceed $2M/MW, with payback periods stretching 7–10 years. Traditional amine scrubbing or PSA systems require:
Strict EU/US regulations (e.g., EU’s 2024 Methane Regulation) limit methane emissions to <0.5% of throughput. Yet:
Biogas composition fluctuates wildly:
Most systems can’t adapt without costly re-engineering.

“Enric’s biogasaufbereitung system reduced our OPEX by 40% compared to our previous amine scrubber. The modular design allowed us to scale from 500 to 2,000 Nm³/h without downtime.”
Dr. Klaus Weber
Technical Director, BioEnergie Park (Germany)
“With Enric’s solution, we achieved 99% methane purity for our CNG station—exceeding California’s strict standards. Their after-sales support is unmatched.”
Mark Johnson
Operations Manager, Shell Clean Energy (USA)
“The EN-BG-500 unit processes our agricultural waste into biomethane with zero odor complaints. The ROI was achieved in just 4.5 years.”

Biogas is the raw gas produced from anaerobic digestion (50–75% CH₄, 25–50% CO₂, and impurities like H₂S). Biomethane is upgraded biogas with ≥97% CH₄, meeting natural gas grid standards (e.g., DVGW G 260 in Germany or ASTM D7895 in the US).
Our pre-treatment stage includes:
This protects the membranes and compressors, extending their lifespan to 10+ years.
ROI varies by region and feedstock, but here’s a breakdown:
| Revenue Stream | Europe (€/year) | USA ($/year) |
|---|---|---|
| Grid Injection (Feed-in Tariff) | €800,000–2M | $500,000–1.5M |
| CNG Sales | €1M–3M | $800,000–2.5M |
| Carbon Credits (LCFS/RINs) | €300,000–1M | $400,000–1.2M |
| Total Revenue (EN-BG-1000) | €2.1M–6M | $1.7M–5M |

★★★★★
“We installed Enric’s EN-BG-500 in 2023. The system has been flawless—zero downtime in 18 months. The remote monitoring saved us £50,000/year in maintenance costs. Highly recommend for anyone serious about biogas.”
★★★★★
“Enric’s team handled all the permitting for our grid injection project in Spain. We went from raw biogas to biomethane in 3 months—half the time of local suppliers. The DVGW certification was seamless.”
★★★★☆
“The EN-BG-200 was perfect for our small-scale farm. The only issue was customs clearance (took 2 extra weeks), but Enric’s team resolved it quickly. Now we’re selling CNG at a profit within 6 months!”
