Furnace slag refers to the solid waste generated during the combustion process, usually including coal slag, coke slag, slag, etc. If these wastes are not properly treated, they will cause pollution to the environment. However, if we can reuse household waste slag, it can not only reduce the burden of waste treatment, but also contribute to the environmental protection industry.

1、 Classification of household waste slag

Household waste slag is a variety of composite materials, including organic, inorganic, metal and other components. Therefore, before reusing, we need to classify the household waste slag. Generally speaking, household waste slag can be divided into the following categories:

1. Organic: including kitchen waste, waste plants, etc.

2. Inorganic materials: including glass, ceramics, stones, etc.

3. Metal category: including iron, copper, aluminum, etc.

4. Other categories: including plastic, paper, etc.

2、 Reuse of household waste slag

1. Brick making with household waste slag

Household waste slag can be made into environmentally friendly bricks, which have the characteristics of waterproofing, fire prevention, sound insulation, and insulation, and can be used in fields such as construction and roads. The method of making environmentally friendly bricks is to mix household waste slag with materials such as cement and lime, and make them through processes such as processing, pressing, and drying. This method not only reduces the amount of waste, but also provides an environmentally friendly material for the construction industry.

2. Fertilizer production from household waste slag

Household waste slag contains rich minerals and organic matter, which can be made into fertilizer. The method of making fertilizer is to mix household waste slag with decomposed organic matter, and make it through fermentation, composting, and other processes. This fertilizer can not only provide a Organic fertilizer for agriculture, but also reduce the amount of garbage.

3. Ceramic production from household waste slag

Household waste slag contains a large amount of silicates and oxides, which can be made into ceramics. The method of making ceramics is to mix household waste slag with materials such as clay and quartz, and make them through processes such as processing, molding, and firing. This method not only reduces the amount of waste, but also provides an environmentally friendly material for the ceramic industry.

4. Domestic waste slag pavement

Household waste slag can be made into road paving materials, which have the characteristics of waterproof, fireproof, and wear-resistant, and can be used in fields such as roads and bridges. The method of making road paving materials is to mix household waste slag with materials such as cement and asphalt, and make them through processes such as processing, pressing, and drying. This method not only reduces the amount of garbage, but also provides an environmentally friendly material for transportation construction.

3、 The significance of reusing household waste slag

The reuse of household waste slag has the following significance:

1. Resource conservation: The reuse of household waste slag can reduce the amount of waste and save resources.

2. Environmental protection: If household waste and slag are not properly treated, they can cause pollution to the environment, and reuse can reduce environmental pollution.

3. Promoting economic development: The reuse of household waste and slag can provide an environmentally friendly material for construction, transportation, agriculture, and other fields, promoting economic development.

4、 Conclusion

The reuse of household waste slag is an environmentally friendly waste treatment method that can reduce the amount of waste, protect the environment, and promote economic development. We should actively promote the method of reusing household waste and slag, so as to turn waste into treasure and contribute to the environmental protection cause.
