Comprehensive utilization method for agricultural wastes and plastic garbage

Abstract

The invention provides a comprehensive utilizing method for agricultural wastes and plastic wastes, which belongs to the waste treatment and utilization field. The comprehensive utilizing method for agricultural wastes and plastic wastes of the invention comprises the following steps that: firstly, the agricultural wastes and the plastic wastes are classified for sorting, wherein, the agricultural wastes adopt crop straws or edible mushroom sticks; secondly, the agricultural wastes are processed to form flammable gas; thirdly, the plastic wastes are processed to form flammable gas; fourthly, the flammable gas obtained through the second and the third steps is stored in a mixed way. The agricultural wastes and the plastic wastes are transformed from wastes into treasure through harmless treatment performed on the agricultural wastes and the urban plastic wastes, and the whole process is safe and reliable without secondary pollution.

Description

technical field [0001] The invention relates to the field of waste treatment and utilization, and specifically provides a method for comprehensive utilization of agricultural waste and plastic waste. Background technique [0002] Together with steel, wood and cement, plastics constitute the four basic materials of modern industry and play an important role in the development of the national economy. Plastic has the advantages of excellent material comprehensive properties, convenient processing, and significant energy saving in production and use, making it widely used in industry, agriculture and people's daily life. With the vigorous development of the plastic industry and its large-scale use, the environmental pollution caused by waste plastic products and plastic garbage is becoming more and more serious. The waste and disposal of plastic products have caused a series of environmental problems, and "white pollution" has become a household name. Plastic materials are syn...

Problems solved by technology

Corrosion resistance and anti-bacteria are one of the great advantages of plastic products, but they have become a headache for scientists after they become garbage. In the absence of air and light, it is difficult for microorganisms to decompose organic matter, and it takes 200 years for plastic waste to be removed from landfills. can be broken down

The third is that after the landfill, the plastic waste is washed away by the rain for a long time, causing a large amount of harmful substances to be brought into the human living environment, causing harm to future generations

However, some pollutants, such as light hydrocarbons, nitrogen compounds, sulfides, dust, and other toxic substances (such as dioxin, DIOXIN), will be produced during the combustion of combustible waste, which will cause exhaust emissions. It even enters the crops and food chain through rainfall, directly threatening people's health

The quality of plastic products produced by melting regeneration is low, and the dirt in waste plastics is easy to contaminate the contents of the container. In the United States, it has been expressly prohibited to use recycled plastics to directly package food
