Foam metal manufacturing process will produce some wastes, such as metal chips, waste gas, waste water, waste liquid, etc. These wastes need to be reasonably treated and recycled to minimize the impact on the environment.
For metal shavings, it can be recycled and reutilized by recycling them into raw materials for reuse. For waste gas and waste water, pollutant management techniques, such as adsorption, oxidation, precipitation, filtration, etc., can be adopted to remove the pollutants therein or reduce the emission concentration before discharge or further treatment. For waste liquids, they can be treated by evaporation, concentration, crystallization, etc., so as to recycle and utilize the useful substances in them, and at the same time reduce the emission of waste.

In addition, the materials and chemicals used in the foam metal manufacturing process need to be sorted, stored, treated and recycled to minimize the impact on the environment. For waste that cannot be recycled, safe and effective waste treatment methods, such as incineration and landfill, should be adopted to minimize its impact on the environment.
In conclusion, reasonable treatment and recycling of waste generated in the foam metal manufacturing process is conducive to reducing the impact on the environment and achieving the goal of sustainable development.
