Slag utilization after domestic Incineration

With the acceleration of urbanization, the amount of household waste is also constantly increasing. In order to solve the problem of garbage disposal, many cities adopt the way of domestic Incineration for disposal. However, the burned slag has become a new problem. This article will introduce the slag utilization method after domestic Incineration, let's have a look.

1、 What is the slag after Incineration?

Domestic Incineration refers to burning domestic waste at high temperature and converting it into ash and slag. Ash refers to inorganic substances such as bricks, ceramics, glass, etc., while furnace slag refers to organic substances such as kitchen waste, paper, etc. The burned slag contains a large amount of organic matter and nutrients, which can be used for soil improvement, fertilizers, and other fields.

2、 Utilization method of slag after domestic Incineration

1. Soil improvement

The slag after Incineration contains a lot of organic matter and nutrient elements, which can be used for soil improvement. Mixed use of slag and soil can improve soil fertility and water retention, improve Soil structure, increase soil aeration and maintain soil temperature. Meanwhile, the microorganisms in the slag can promote the decomposition of organic matter in the soil and accelerate plant growth.

2. Fertilizers

The slag after domestic Incineration can be used as fertilizer. Slag contains a large amount of nutrients such as nitrogen, phosphorus, and potassium, which can be used as nutrients for plant growth. The slag can be mixed with other Organic fertilizer to improve the effect of fertilizer and promote the growth of plants.

3. Building materials

The slag after domestic Incineration can be used for building materials manufacturing. Slag contains a lot of silicate, Aluminate and other substances, which can be used to manufacture cement, bricks and other building materials. At the same time, the organic matter in the slag can be used to produce Biochar for soil improvement.

3、 Precautions for slag utilization after domestic Incineration

1. The treatment of slag requires professional personnel and cannot be carried out arbitrarily.

2. The slag contains organic matter and needs to be classified to avoid pollution to the environment.

3. The slag contains a large amount of heavy metals and other harmful substances, which need to be treated to avoid affecting human health.

Summary

The slag after Incineration is a substance with high organic content, which can be used in soil improvement, fertilizer, building materials and other fields. However, the treatment of slag requires professional personnel and cannot be carried out arbitrarily. At the same time, slag contains a large amount of heavy metals and other harmful substances, which need to be treated to avoid affecting human health. We should actively explore the utilization method of slag after domestic Incineration, so as to realize the resource utilization of garbage, protect the environment and promote sustainable development.
