MATURE CONFIGURATION, LOW-CAPEX, SUITED TO INDONESIAN CLIMATE

Feedstock receiving

CLAD lagoon

Biogas

Upgrading

MSW + animal feedstock

25-35 day HRT mesophilic 35-40°C

55-65% CH4 under membrane

Membrane or PSA to >=97% CH4

OPERATING PARAMETERS

WHY CLAD

ParameterValue
Hydraulic retention time25 – 35 days
Operating temperatureMesophilic 35 – 40 °C (no supplemental heating)
Raw biogas methane55 – 65%
Parasitic load5 – 10% of biogas production
Operating utilization>= 90% (Penang reference target)
Upgraded CBG methane>= 97% (PGN pipeline spec)

• Proven configuration — operating at Penang Bio-Methane plant

• Lower CAPEX than CSTR or plug-flow alternatives

• Indonesian climate supports mesophilic operation without heating

• Modular and scalable across 2.5 – 5.0 ha site footprints

• Digestate dewatered: solids → biofertilizer · liquid → LTP

• Critical components from Europe; civils Indonesian

BALANCE OF PLANT

MRF tier matched to MSW purity (Pasarjaya none · Lamsel light · Bandung full in-kind) · Digestate dewatering with leachate treatment plant (LTP) · Biogas upgrading sized to plant throughput · PGN pipeline interconnect or Pertamina truck loading
