- Collection of gold, silver and copper sediment sludge from waste incineration ash
What is the collection of gold, silver and copper sediment sludge from waste incineration ash?
Local government incineration plants generate waste incineration ash from their incinerators.
The Envipro Group collects gold, silver and copper sediment sludge (concentrated gold, silver, copper, platinum and palladium sediment sludge) contained in this waste incineration ash.
Social issues
Urban mines, such as discarded automobiles and home appliances, are attracting attention.
Although there is increasing awareness due to the enforcement of the Act on Promotion of Recycling of Small Waste Electrical and. Electronic Equipment. most of the “waste incineration ash from municipal waste,” which contains many metals, is still disposed of in landfills without collecting most of the metals.
This project improves the recycling rate of waste incineration ash by collecting metals (unused resources), including precious metals, and at the same time contributes to extending the life of final disposal sites by reducing the amount of landfill disposal.
Target market
In addition to the collection of gold, silver and copper sediment sludge from riddling and other ash*, we will also aim to collect it from incinerator bottom ash.
*Riddling ash: Ash in waste incineration ash that falls from the grate of a stoker furnace
*According to our company's data

Business features
Improving the recycling rate of local governments
By collecting metals from waste incineration ash that had previously been disposed of, we improve the recycling rate of local governments. We are also working to turn the ash itself into a resource.
Improving local government revenues
Disposal of waste incineration ash used to be a burden for which disposal fees had to be paid.
We evaluate the value of precious metals and can purchase riddling ash for value, thereby contributing to the improvement of local government revenues.
Easing the shortage of final disposal sites in municipalities
New final disposal sites are difficult to set up, and the remaining capacity of final disposal sites is decreasing nationwide. We reduce the volume of waste incineration ash to reduce the amount of landfill space, thereby contributing to securing the remaining capacity.
