Do not make grinding materials into industrial waste

By changing the grinding material for peeling the paint film from the sand to a metal that can be recycled and reused, we succeeded in turning industrial waste into only the paint film waste that has been peeled off..
The reduction amount is 1/40 of that of the conventional method.
In the last fiscal year, we contributed to the reduction of about 65,000 tons of industrial waste.


Reduction of dust generation



Low cost, improved work efficiency

In the construction of 1,000 square meters, approximately 1t of paint film waste and 40t of grinding material waste were discharged.The recycling and reuse system, which uses the difference in the weight of the coating film waste and the grinding material to separate the waste, has made it possible to make only the coating film waste.


Greenhouse gases significantly cut

Since industrial waste becomes only paint film waste, greenhouse gases emitted during transportation and disposal are also reduced.
Last year, we succeeded in reducing greenhouse gas emissions by approximately 13,800 tons and 5.6 units at the Tokyo Dome.








Effect in the field


abrasive circulation type blasting

Pioneer of grinding material recycling type blast


Do you use hard (brittle) grinding materials?

Grinding materials with high hardness have a low life value, wear quickly, and are prone to sticking to steel, which leads to an increase in industrial waste and a decrease in coating quality.

is the sorting device integrated with the blast tank?

If the sorting device and the blast tank are not integrated, there is a risk that harmful dust will scatter around the construction site.

Do you use a blast-only curing sheet?

It is possible to prevent the leakage of harmful dust by curing and construction with a sheet dedicated to blasting.

Do you manage the PCB contents separately from other equipment?

If work is performed without a clear distinction between dedicated PCB materials and lead materials other than PCBs, there is a risk of contamination of sites that do not contain PCB.

Is it equipped with a suction force that can efficiently recover metal-based abrasives?

If the suction force is insufficient, the grinding agent cannot be recovered efficiently and the efficiency of the blasting operation falls, leading to delays in construction periods and increases in construction costs.
