The project is to introduce bulky waste shredding and disposal equipment in the waste transfer station to shred and dispose the bulky waste including waste sofas, waste mattresses and waste furniture, so as to achieve rapid volume reduction and facilitate subsequent transportation, incineration and resource recycling. The customer said bulky waste is a kind of waste that makes them headache, and the direct compression effect is not ideal. With the participation of double-shaft shredder, the problem is solved.
