The document summarizes Recupera's process for recovering waste plastics from oceans through low-temperature conversion (LTC) to syngas and further processing to hydrogen and other valuable chemicals and industrial gases. Recupera operates a commercial demonstration plant in Slovenia and aims to construct a 1 tonne per hour plant to process plastic residues into syngas, hydrogen, and other outputs. The process provides an economically feasible and environmentally friendly solution to the problems of plastic pollution in oceans and landfills.

3. INTRODUCTION
Company: Recupera - The White Hydrogen Company
Location: Commercial Demonstration plant in Celje, Slovenia.
Operational plants near the collection site on shore or on board
Objective: Commercial demonstration of thermal, distributed, compact,
ev. mobile, on-and off-shore, low temperature conversion (LTC) of
plastic residues to syngas and further processing to electric, thermal
energy and valuable chemicals, and industrial gases, specially
hydrogen
Operational Focus: Plastics to H2.
Goal: Construction of a demonstration plant, closed, compact,
1t/h, 8000h/year

7. SOLUTION to PROBLEMS
ANALYSIS
Plastic pollution is a planetary threat, affecting nearly every marine and freshwater
ecosystem globally. In response, multilevel mitigation strategies are being adopted but with
a lack of quantitative assessment of how such strategies reduce plastic emissions. We
assessed the impact of three broad management strategies, plastic waste reduction, waste
management, and environmental recovery, at different levels of effort to estimate plastic
emissions to 2030 for 173 countries. We estimate that 19 to 23 million metric tons, or
11%, of plastic waste generated globally in 2016 entered aquatic ecosystems. Considering
the ambitious commitments currently set by governments, annual emissions may reach up
to 53 million metric tons per year by 2030. To reduce emissions to a level well below this
prediction, extraordinary efforts to transform the global plastics economy are needed.

8. SOLUTION to PROBLEMS
5 trillion pieces of plastics currently litter the oceans
Dispersed in the 5 oceans
According to Science magazine Feb 2015, 8 million
metric tonnes per year of plastics are dumped into
the oceans
Macro, micro and nano plastics (perfect sized for
direct gasification)
