Plastic removed from the GPGP using shipboard HTL for different surface plastic concentrations

Plastic concentration in GPGP* (g⋅km−2)	Plastic removed per year† (kg)	Percentage of plastic-derived fuel consumed yearly‡ (%)
2,500	1.2 × 107	580
1,000	4.6 × 106	230
500	2.3 × 106	120
200	9.2 × 105	50
50	2.3 × 105	12

* Surface concentration of plastic in the GPGP (1) for a fixed value of 79,000 tons of plastic contained in the GPGP(2).

^† Plastic removed from 2,500 booms per year with a 70% collection efficiency.

^‡ Percentage of total required fuel consumption that can be covered with plastic-derived fuels assuming a fuel density of 0.84 kg/L, a conversion range of 60%, and fuel consumption of 90 GPH.
