Business Korea reported that Hyundai Steel has started to reduce greenhouse gas emissions by using cattle manure in its steelmaking process. The plan is to recycle livestock waste and reduce greenhouse gases by using eco-friendly fuels based on excrement from cows instead of coal. Hyundai Steel signed a business agreement with the Ministry of Agriculture, Food and Rural Affairs and the National Agricultural Cooperative Federation to promote production and use of solid fuel based on cows’ feces. Hyundai Steel plans to consider injecting solid fuel based on cows’ feces as furnace fuel after conducting operational tests in the future. Hyundai Steel and the two organizations aim to kill two birds with one stone by changing livestock manure, a headache for livestock farmers, into a solid fuel, reducing livestock manure and using them as an eco-friendly fuel in steel mills. Four tons of livestock waste can be processed into one ton of solid fuels based on cattle excrement. This means that 1.5 tons of greenhouse gas emissions do not take place. About 22 million tons of cattle excrement are generated every year in Korea but most of them are used as compost. Korea has generated more than two million tons of greenhouse gases annually. The Ministry of Agriculture, Food and Rural Affairs believes that even if only 10 percent of the cattle excrement is solid fuel, greenhouse gas emissions can be reduced by about 300,000 tons. In addition, one ton of manure-based solid fuel generates as much energy as 0.5 tons of bituminous coal. Therefore, using manure-based solid fuels instead of bituminous coal not only reduces greenhouse gas emissions but cuts down on the cost of importing bituminous coal. Hyundai Steel began developing a technology that uses cattle excrement as a steel mill fuel in 2012 and applied for a patent in 2014. The problems of cattle feces collection and solid fuel manufacturing have impeded the commercialization of the technology along with economic feasibility.
