6. Upgrading Biogas to RNG
Biogas is produced from the
anaerobic digestion of
organic waste matter
Remove impurities to produce
RNG for use as CNG vehicle fuel
or pipeline injection.
7. What is Biogas & Biomethane (RNG)?
Biogas
Mixture of gases produced
by the break down of
organic matter in an oxygen
free environment
CH4: ~60 %
CO2: ~39 %
N2+O2: < 1%
H2S: 50 – 5,000 ppm
H2O: Saturated
Siloxanes: Trace
Biomethane (RNG)
Upgraded biogas that is
interchangeable with
natural gas
CH4: > 96 %
CO2: ~1 %
O2: < 0.4 %
Total inerts: < 4 %
H2S: < 1 ppm
H2O: < 1 ppm
Siloxanes: < 1 ppm
8. A technology independent company
• Greenlane is evolving from being just a waster wash
supplier to becoming a technology independent solution
provider. Some of the technologies we offer include:
Membranes PSA Water Wash

12. Surrey Biofuels Facility
Project Site
• Source Separated Organics Facility in Surrey BC
Objective
• Close the loop on the city – reduce/recover organic waste
Process
• Produce biogas using anaerobic digesters to break down
organic waste.
• Upgrade biogas to RNG using Greenlane system
• Recover CO2 to use as part of the process.
RNG Use
• Inject into FortisBC pipeline & fuel CNG vehicles.

17. Greenlane Water Wash Overview
1. Biogas compressed
& fed to scrubber to
remove impurities
4. Clean gas purified for
customer delivery3. Methane not recovered in
scrubbing stage gets “flashed
off” and recovered
2. Biogas showered with
water, CH4 passes
through and impurities
trapped in water
