Abstract:China produces a large number of scrap iron barrels every year that suffer from rusting, deformation, and stubborn chemical residues inside. If discarded at random, they will have a negative impact on the surrounding environment, especially the ones used to contain hazardous waste which could cause serious pollution and must be properly disposed of. Therefore, the standardized recycling of scrap iron barrels can not only save resources, energy, and production costs, but also protect the ecological environment, bringing economic and environmental benefits. The use of scrap iron barrel recycling equipment with high automation level and large processing capacity is conducive to improving product quality, bettering the working environment, reducing environmental pollution, and saving energy. The reconditioned iron barrels then can be sold out and reused as packaging barrels, which accords with the requirements of circular economy and low-carbon economy.
