◯Remnants are reprocessed after being pulverized
We pulverize the offcuts generated in the manufacturing process of the ALC (aerated concrete) “Siporex” that we sell, reprocess them, and ship them as ALC.
In the construction sector, we have succeeded in streamlining and omitting product packaging, contributing to the reduction of greenhouse gas emissions.
◯Supply of fluorine-free raw materials
Firefly stone has been used as a useful ingredient in the steel manufacturing process. However, there was a problem because the raw material contained harmful fluorine.
Daisen worked on fluorine-free products, supplied calcium aluminate as a substitute product to steel manufacturers, and succeeded in removing fluorine.
In the Equipment Department, we propose facilities and equipment to customers from the perspective of energy conservation and removal of hazardous substances.
◯Recycling of castings is common sense in the industry
Castings have been recycled for a long time and have been reborn as casting products again, playing an active role in society.
As a trading company specializing in castings, Daisen strives to collect discarded castings and contributes to zero emissions in casting production systems.
In addition, waste oil such as machine lubricating oil that is generated during casting processing is reprocessed as fuel and is the source of the foundry's operation.
◯Use fuel to reduce waste
In addition to collecting PET bottles, Daisen has long reprocessed waste plastics and supplied them to the industrial world.
This can be said to be an effective use of two birds with one stone, which is both energy saving and waste reduction.
◯Creating safe roads with safety features, etc
Used insulators, slag (slag) produced by-products from steel mills, and waste plastics are used and processed into roadbed materials.
It is used for road construction with functionality such as anti-slip and water permeability.
Adding not only the scenery but also the safety function has led to an increase in demand.
◯Recovering for advanced industries
Rare metals such as zinc and lead are valuable resources for advanced industries.
Daisen is working on recovering and reusing valuable materials, such as extracting rare metals from sludge and dust discharged from electric furnace manufacturers.
◯For counterweights for construction machinery and heavy machinery
Daisen sells and reuses molten metal for local governments, by-product generated from waste incineration facilities (Nippon Steel gasification melting furnaces) operated by Nippon Steel nationwide, mainly as weights for construction and heavy machinery. doing.
◯Know-how of building greening construction
A joint conduit for power lines to remove utility poles and other obstructions from streets, alleviate traffic congestion, and contribute to the appearance of the landscape.
Daisen sells materials such as pipes, hand holes, iron lids, etc. for this construction in the civil engineering department, and plays a role in creating a comfortable town.
The civil engineering department also has unique know-how in building greening work, and is expected to play an even greater role in the greening business in urban areas, where demand is expected to increase in the future.
