- What We Do
Oshima Industry is a one-stop waste disposal plant that transports and disposes everything considered to be "waste". With two incinerators, our disposal facility tirelessly strives for operational and cost efficiency. Our number one priority is to respect the community and its surrounding environment. We have perfected countermeasures for dioxin emissions, utilize waste heat emanating from the incinerator, and purify wastewater to be safe enough to drink before reintroducing the water back into the river.
In 2015 we were certified as an outstanding industrial waste disposal company.
There are 20 types of waste that can be disposed onsite. Because all waste is collected, transported, and disposed within the same plant, there is little risk of illegal dumping and the disposing process is executed in a closed environment.
Utilizing the waste heat emanating the incineration plant, we recycle food waste from food producers by desiccating bread, noodles, and vegetables to make livestock feed. We are also proactively engaged in thermal recycling and cascade recycling.
Oshima Industry has strengthened its partnership with cement companies for businesses that are striving to achieve zero emissions. After utilizing burnable waste for thermal recycling, ashes and other remaining materials of the burnable waste is used as raw materials and fuel for cement. Oshima Industry proposes the most suitable recycling method for each type of waste.
We incinerate activated coal that contains rare metals to extract and concentrate the metals. Oshima Industry is the only plant in Kyushu that is capable of concentrating rare metals. The concentration process reduces transportation costs.
Oshima Industry transports low concentration PCB materials, which are difficult to process, in order to reduce cost of disposal. These materials are disposed safely at cooperating companies. We provide solutions to companies have been waiting to dispose these materials for a long time and companies who are experiencing trouble with leaks caused by long-term storage.
We dispose diapers, needles, and other kinds of hazardous waste that require special treatment.
