Recycling of metal scrap(ferrous, nonferous metals)
Metal scrap is a resource derived from used ferrous or nonferrous metals which became unnecessary.
In particular, ferrous scrap can be repeatedly resurrected as a new ferrous finished product, and therefore is considered an excellent recycling metal.
The Group is able to provide integrated services, from the removal, transport and collection of business-related metal scrap at plants and construction sites to the associated demolition work and recycling. We are working to recycle resources not only through technology, but also through a wide range of services that meet customer needs. We are also able to bring in small quantities from ordinary households and handle collection and transportation.
Also, metal scrap is generally a chargeable transaction material. The traceability of these materials is not required, but we are striving to make processing transparent because we have a social responsibility to process the assets of our customers. We strive to provide safe and secure services.
Collection of precious metals from waste incineration ash
While metal collection from so-called "urban mines" such as scrapped automobiles and home appliances is being recognized due to the enforcement of the Small Home Appliance Recycling Law, some of the municipal waste incineration ash containing a large amount of metal is recycled as a raw material for cement, however most of it is not recycled and is disposed of in landfills.
Through years of research and achievements in our group, we have developed a technology to collect precious metals from waste incineration ash discharged by general waste incineration facilities. A patent on the technology was issued in January 2019. By utilizing this technology, we are not only improving the resource recovery rate of waste and precious metals, but also contributing to the reduction of the amount of incinerated ash disposed of in landfills.
Recycling of mix metals
"Mix metals" scrap is composed of plastic and several kinds of metals, and is low value and difficult to dismantle, so it was scrap that could only be profitable by hand dismantling in a country with low labor costs. It was rejected by domestic scrap companies because it was difficult to dismantle, and it was advantageously exported to China until now.
However, due to the revision of the Basel Law in Japan and the recent change in China's environmental policy, it has become difficult to export to China, and the problem of unprocessable "mixed metal" scrap staying in the country has emerged.
The Group is also working to recycle mix metals scrap by utilizing the know-how and equipment gained through the development of shredding and sorting technology, and technology accumulated in the past is being utilized here as well.
Production of Solid Fuel (RPF)
RPF (Refuse Paper and Plastic Fuel) is a high-grade solid fuel that is made by compressing mainly waste plastics and paper.
By compressing and solidifying waste plastics and paper, which are difficult to recycle as materials, they can be turned into energy fuels.
RPF is widely used in the paper industry and steel industry as an alternative fuel to fossil fuels such as coal due to its stable quality, controllable calorific value, high calorie content, easy handling, and other benefits.
RPF is considered to be an environment-friendly fuel because it emits about 33% less CO₂ than coal, and its value has been looked at again.
Since our plants are operated under the RE100, CO₂ emissions from the RPF manufacturing process are further reduced. Therefore, the RPF produced by the Group is a low-carbon fuel with even lower CO₂ emissions.
RPF is expected to be an environment-friendly fuel that contributes to the promotion of recycling of waste plastics and a low-carbon society.
Wide-ranging one-stop services
Our Group offer one-stop services that range from collection, transportation, and disposal of waste to building demolition. Usually, removal of machinery and equipment from factories and offices prior to demolition requires separate contracts with multiple companies, each having specific licenses for collection, transportation, or disposal of discarded articles (including those containing low-concentration PCB or asbestos), or remediation of contaminated soil after demolition. Our group can offer one-stop services encompassing waste removal and disposal, demolition of structures, and remediation of contaminated soil after demolition, thus helping to increase the recycling rate and at the same time reducing the burden and costs on the part of the customer.
Recycling of metallic industrial waste
The metals including precious metals contained in waste materials such as used cars and household appliances are often referred to as “urban mines,” a reserve of many useful resources. However, advanced technologies are required to convert such composite waste materials into materials ready for use. We shred the “urban mine” waste materials and apply optimum combinations of magnetic force, wind power, wet specific gravity, dry specific gravity, color, and other separation technologies to separate and concentrate individual materials to achieve a high level of resource recovery. Marking one of the cornerstones evidencing the technologies and track record behind its diverse business, ECONECOL inc. became certified for the R2 Standard in August 2019. The R2 Standard refers to a certification program managed under the guidance of the U. S. Environmental Protection Agency to encourage and evaluate responsible actions for electrical and electronic equipment recyclers. The R2 Standard covers recycling of used electrical and electronic equipment such as mobile phones, TV sets, and computers. Because of the reliability of this certification, R2 certified recyclers are increasingly preferred in the market. We will continue to strive to promote responsible recycling of electric/electronic equipment, ITC equipment and batteries.
