processing equipment for blast furnace waste

Injection of coal and waste plastics in blast furnaces

waste plastics are introduced into processes designed to yield chemical feedstocks rather than heat. This category includes the utilisation of plastics in blast furnaces (BFs). BF usage also recovers energy from the waste plastics and so it is sometimes categorised as energy recovery. The preferred classification in the EU Directive on waste ...
