How to dispose of waste garbage bags
How to dispose of waste garbage bags? Nowadays, when you go to the supermarket, you will come into contact with plastic bags for everything. Garbage bags, as the name suggests, are bags for garbage. They are small bags, but they bring great convenience to thousands of households. So how to deal with waste garbage bags? Come take a look with us below.
How to deal with waste garbage bags 1
1. Fuel
1. Initially, many plastic recycling methods use landfill or burning, resulting in a huge waste of resources. Therefore, waste plastics are used in foreign countries to replace coal, oil and coke in blast furnace injection, used in cement rotary kilns to replace coal to bake cement, and made into waste solid fuel (RDF) for power generation, with promising results.
2. RDF technology was initially developed by the United States. In recent years, in view of the lack of landfills in Japan, the severe corrosion of HCI on boilers when burning chlorine-containing waste plastics, and the generation of dioxins during the combustion process to pollute the environment, Japan uses the characteristics of high calorific value of waste plastics to mix various After combustible waste is made into RDF with a calorific value of 20933kJ/kg and uniform particle size, even if the chlorine is diluted, it can be easily stored, transported and used as a substitute for coal in other boilers and industrial kilns.
3. The waste plastic injection technology in the blast furnace is also a new method for treating waste plastics that uses the high calorific value of waste plastics to make waste plastics into materials with suitable particle size and spray them into the blast furnace to replace coke or pulverized coal. method. The use of waste plastics injected in foreign blast furnaces shows that the utilization rate of waste plastics reaches 80%, the emissions are 0.1%-1.0% of the combustion volume, the generation of harmful gases is less, and the treatment cost is low. Blast furnace injection waste plastic technology opens up a new way for the comprehensive utilization of waste plastics and management of "white pollution", and also provides a new method for energy conservation and efficiency improvement of metallurgical enterprises. Germany and Japan have successfully used it since 1995.
2. Power generation
1. Waste-to-solid fuel power generation was used earlier in the United States, and there are 37 RDF power stations, accounting for 21.6% of waste-to-energy power stations. Japan has now realized the huge potential of generating electricity from waste plastics. Japan's joint overhaul has changed some small waste combustion stations into RDF production stations to facilitate centralized and continuous high-efficiency power generation. The steam parameters of the waste power station have been increased from 30012 to about 45012, and the power generation efficiency has been increased from the original 15% to 45012. 20%-25%.
2. Plastic bags are essential items in people’s daily lives and are often used to hold other items. They are widely used because of their cheapness, extremely light weight, large capacity, and easy storage. However, due to the shortcomings of extremely long degradation cycles and difficult processing, plastic bags are blocked from use and production by some countries. Since June 1, 2008, my country has implemented a plastic restriction order: "The paid use of plastic shopping bags shall be implemented in all supermarkets, shopping malls, bazaars and other product retail locations. Plastic shopping bags shall not be provided free of charge, and nationwide Prohibit the production, sale, and use of plastic shopping bags with a thickness less than 0.025 mm”
3. Harms
1. Plastic bags do bring convenience to people’s lives, but this convenience But it brings lasting harm.
2. The recycling value of plastic bags is low. During use, in addition to being scattered on city streets, tourist areas, water bodies, and at both ends of highways and railways, causing "visual pollution", it also has potential harm. The plastic structure is stable, not easily degraded by natural microorganisms, and does not separate for a long time in the natural environment. This means that if waste plastic waste is not recycled, it will become pollutants in the environment and continue to accumulate for a long time, which will cause greater harm to the environment. How to dispose of waste garbage bags 2
Method 1: You can put a medium-sized plastic bag on the broom. We often worry about hair sticking to the broom. At this time, as long as you put a plastic bag on the broom, you can sweep the floor easily without worrying about hair sticking to it. The floor swept this way is cleaner than usual.
Method 2: You can use a small plastic bag to wipe the oil pan. I believe many people are worried about cleaning the oil pan. In fact, as long as you wipe the pan with a plastic bag before washing it, you can remove most of the oil, and then you can clean the pan better. I've tried it and it works really well.
Method 3: You can use large plastic bags as garbage bags.
Purchasing garbage bags is also an expense. Why not use discarded plastic bags as garbage bags to make use of waste and save money on buying garbage bags.
Method 4: Put plastic bags on your shoes on rainy days to make them waterproof. When it rains, some of our shoes often get wet from the rain. Putting plastic bags on our shoes can effectively isolate the rainwater, which solves the problem of not having rain boots.
Method 5: Put a plastic bag on when scraping fish scales. This will prevent the fish scales from splashing and is also very convenient to take care of.
