South Korea`s top power-equipment maker Doosan Heavy Industries & Construction Co. said Thursday that it has signed a memorandum of understanding with a local company to jointly develop technology and systems to produce hydrogen from waste plastics and vinyls.
Under the MOU, Doosan Heavy’s partner company RevoTech Co. will be responsible for continuous pyrolysis process of waste plastics to produce gas, while Doosan Heavy will develop core facilities and processes to reform pyrolysis gas into hydrogen.
The continuous pyrolysis technology enables continuous production through continued fuel inputs, leading to easy scaling up and high economic efficiency.
Doosan Heavy said it will establish a hydrogen reformer at its partner company in Mungyeong, Gyeongbuk Province to extract hydrogen of about 0.3 ton from gas produced from waste plastics and vinyls within this year. Doosan Heavy aims to increase the daily production of hydrogen to more than 3 tons.
In Korea, over 8 million tons of waste plastics are generated every year, and about half of them subject to burial, incineration, and processing for solid refuse fuel can be used for this technology, said Song Yong-jin, vice president at Doosan Heavy Industries & Construction.
Hydrogenation of waste plastics can contribute to the realization of resource circulation and carbon neutrality and the produced hydrogen can be used in fuel cells and hydrogen gas turbines in the future, he added.
