This document discusses Recupera BioEnergia's low temperature conversion (LTC) technology for transforming waste plastics into hydrogen. The LTC process involves gasifying waste feedstocks at low temperatures to produce syngas which can then be converted into hydrogen or other chemicals. Recupera offers waste management solutions using this proprietary thermal conversion technology that produces ultra-pure hydrogen while minimizing emissions and maximizing energy efficiency. The company seeks partners who can provide waste feedstock and help address environmental issues through this sustainable waste-to-energy process.

12. COMPARATIVE ADVANTAGES
ANALYSIS
Emission levels well below the levels approved by EU.
Corrosion-free
60% lower working temperature → less material fatigue
Conventional incineration plants supply a max. 35% power, the
LTC and MTC plants, on the other hand, 65% electric power
All plants are built from stainless steel
No slagging → low maintenance
No additional costly flue gas cleanup system is necessary.

13. COMPARATIVE ADVANTAGES
No filter required
Industrial residues are completely recycled
No odor development → underpressure
No waste accumulation
Low cost of final disposal
Product line flexibility

14. LTC TECHNOLOGY
Compact plant
Motile
Industrial construction method
Validated

17. MAINTENANCE AND OPERATIONAL
The plants are redundant in design, only 7.5% downtimes incl.
maintenance
The plants guarantees operational availability of approx. 8,050 h/yr
Energy storage units (2 days production) are used to ensure optimum
efficiency of LTC and MTC plants and to cover peak loads
Maintenance intervals are:
> every 23 operating hours, an automatic one-hour self-check (at night)
> every 8,050 operating hours, a general maintenance over 14 days
RELIABILITY

18. EMISSIONS
Total dust < 5 mg/m³
Carbon monoxide (CO) < 20 m g/m³
Nitrogen oxides (NOx) < 20 micg/m³
Sulfur dioxide (SO2) < 10 m g/m³
other problematical substances:
NH3, HCl < 5 mg/m³
CN, HF,H2S < 0,3 mg/m³
As, Co, Ni, Pb, Se, Te < 0,3 mg/m³
Cr, Cu, F, Mn, Sb, Sn, V < 0,3 mg/m³
Cd, Hg, Tl < 0,03 mg/m³
2,3,7,8-TCDD equivalents < 0,03 ng/m³
a) The normal sound level of turbines is
65 [dB]. By carving or shelling the
containers the level can be reduced far
below 65 [dB].
b) No unpleasant odour due to plant
design! Bad smell can occur either
before the plant or before the cryogenic
section corresponding to levels at
material storage.
c) CO2 Emissions: CO2 emissions amount
to 0,365 [g/kWh] net current output.
True recycling
