Waste sorting and treatment leads a low-carbon life

With the improvement of people's lives, the pollution of garbage has become more and more serious.

1.The Hazards of Garbage

Occupy large amounts of land.

Pollute farmland. Waste fertilizer causes soil slag, and slag soil loses 0.5-1 ton of moisture per mu per day compared with normal soil.

Pollute groundwater: Industrial waste discharged from mines, steel plants, etc. contains many harmful substances, such as mercury, lead, chromium, etc. These substances will go deep into the ground under the sun and rain, thus polluting the groundwater.

Pollute the atmosphere. Some organic substances in industrial waste residues can produce a foul smell through biological decomposition at a certain temperature, thereby polluting the atmosphere.

With the development of the economy and the improvement of people's lives, urban garbage is piled up into mountains. Waste Disposal has become an urgent issue in the comprehensive improvement of the urban environment.

The composition of domestic waste is diverse, some can be recycled directly, some can be composted, and some must be incinerated, garbage collected separately, and scientifically treated according to the different characteristics of various types of garbage, which can save resources and prevent pollution.

Some harmful gases, such as HCl, HF, SO2, and nitrogen oxide compounds, organic matter, and slag are generated when garbage is incinerated. If they are discharged directly into the environment, it will also cause pollution, so it is necessary to send the garbage to the incinerator for centralized treatment.

With the continuous development and improvement of waste treatment technology, urban waste is transitioning from stacking treatment to landfilling, and landfilling technology is gradually becoming hygienic, economical, and efficient. The ash, bricks, ceramic lamp materials, and various residues produced in the garbage must be disposed of by landfill. The landfill must meet the sanitary landfill standards: the water content of the landfill is less than 20%-30%, and the inorganic content is greater than 60%.

Our lives are inseparable from all kinds of batteries, but the environmental pollution caused by acid, alkali, and other electrolytes and heavy metals in waste batteries cannot be ignored. Whether it is a disposable battery or a rechargeable battery, if it contains mercury, cadmium, lead, or sulfuric acid, it may pollute the environment. Companies improve production processes to reduce harmful substances in dry batteries, such as developing mercury-free or low-mercury batteries. We also don't throw away batteries everywhere and do a good job of Waste Recycling used batteries.

Recycling various waste plastics.

Waste Management Level

 The waste management plant shares this article for you.

In recent years, society, companies, and legislators have tended to regard high recovery rates as the main goal of sustainable development work. More comprehensive methods such as the circular economy and life cycle analysis, which look at the overall environmental impact of resource use, have overshadowed this idea.

The waste hierarchy is usually displayed as an inverted triangle, which provides a hierarchical method to show the preferred and non-preferred methods of solid waste generation and management. The specific names and numbers of the actual categories may vary, depending on the specific group of people using this model, but the basic thinking process is to avoid consumption and reduce sources and reuse is preferable to recycling, and recycling is preferable to recycling. Waste is converted into energy, and ultimately into landfill.

Reduce source and reuse

The best way to manage waste is not to create waste in the first place. This may involve the choice of avoiding unnecessary consumption of goods and services, and it may also include the purposeful reduction of inputs into creating products by reducing the source. This source reduction effort can include reducing the use of raw materials and saving energy, as well as reducing waste pollution and toxicity. Popular initiatives include reducing packaging, improving energy-efficient production and facilities, using renewable energy, and improving fuel efficiency in cargo transportation. The reduction in water consumption and water footprint has recently become the focus of waste reduction efforts.

Reuse is another powerful means to avoid waste. For example, a reusable packaging system can eliminate the need for disposable packaging, and can also provide better product protection, thereby reducing product damage and related losses. In a broader sense, creating more durable goods may be a useful way to reduce waste.

Recycling and composting

Managing pallet packaging retrieval procedures from multiple locations requires communication, coordination, and commitment to ensure success. If it is impossible to reduce the original source or use durable reusable commodities, the next preferred method involves product recycling or organic composting.

Recycling involves collecting, sorting, and processing products into raw materials, which can be used as inputs for the production of new products. For its part, product recycling usually produces a material that is more energy-efficient, less polluting, and more expensive to produce, while avoiding the consumption of raw materials. Take aluminum as an example. In 2013, 60.2 billion aluminum cans were recycled and reused in the United States, with a recycling rate of 66.7%. In the recycling process, the use of 17 million barrels of gasoline was avoided because the energy required to process the recycled materials is less than the original content.

Composting involves the removal of organic materials such as garden decorations and food residues from the landfill, thereby preventing the emission of harmful greenhouse gases.

Waste to energy

The waste-to-energy (WTE) process involves capturing energy from waste. This can be achieved through a variety of methods, including waste incineration, pyrolysis, anaerobic, digestion, gasification, and landfill gas recovery.

For example, in Sweden, about half of solid waste is incinerated to generate electricity. Pyrolysis is used in processes such as generating clean energy from used tires and converting waste plastics into oil.

Handling and disposal

Disposal is the ultimate choice in the waste hierarchy, but it is a key component of integrated waste management. The landfill is the most common disposal method, and its design, operation and end of life requirements are strictly controlled. In the United States, landfills must comply with strict standards established by the EPA and are usually regulated at the state, tribal, or local level.

Even in the landfill, attention must be paid to recovery. The methane gas produced by the decay of organic matter can be captured for energy. After being closed, the landfill can be covered and reused for other purposes, such as parks or golf courses.

The Eight Categories of Waste Management

Waste management includes source reduction and reuse, animal feeding, recycling, composting, fermentation, landfill, incineration, and land use. Reducing and reusing some of these methods can start from the comfort of your own home.

A variety of methods of construction and demolition waste treatment

Although there are many ways to deal with waste, in this section, let's look at some of the most common methods you should know about waste management.

landfills

Dumping everyday waste/refuse into landfills is the most widely used method of waste disposal today. The focus of the waste disposal process is to bury the waste in the ground. Landfills are common in developing countries.

There is a method used to eliminate the smell and danger of garbage, and then put it underground.

Admittedly, this is the most popular method of waste disposal, but it is certainly not the only procedure, and it may open up a variety of Spaces. This approach is becoming increasingly rare, despite the lack of available space and the presence of methane and other landfill gas, both of which can lead to many pollution problems. Landfills cause air and water pollution, seriously contaminate the environment, and may cause fatal injuries to human and animal lives. Many areas are reconsidering the use of landfills.

Incineration/combustion

Incineration or combustion is a type of disposal method in which municipal solid waste is burned at high temperatures. The process eventually converts them into residues and gaseous products.

The greatest advantage of this method is that it can reduce the volume of solid waste to 20 to 30 percent of the original volume. In addition, it reduces the amount of space they take up and also reduces the pressure on landfills.

Incinerators are primarily used for heat treatment to convert solid waste into heat, gas, steam, and ash. Incineration is also common in countries that no longer have space for landfills, such as the United States and Japan.

Recycling and Reuse

Resource recovery is the process of using useful discarded items for a specific next use. These discarded items are then processed to extract or recycle materials and resources, or to convert them into energy in the form of usable heat, electricity, or fuel. Recycling is the process of converting waste products into new products to prevent the consumption of energy and fresh raw materials. Recycling is the third part of waste reduction, reuse, and recovery hierarchy. The idea behind recycling is to reduce energy consumption, reduce the number of landfills, reduce air and water pollution, reduce greenhouse gas emissions, and conserve natural resources for future use.

Plasma gasification

Plasma gasification is another form of waste management. Plasmas are mainly electrically charged or highly ionized gases. Lighting is one type of plasma produced at temperatures over 12,600°F. With this waste treatment, the container can use characteristic plasma torches operating at +10,000°F, thus creating a gasification zone to convert solid or liquid waste into syngas before 3,000°F. During the process of plasma gasification of solid waste, the molecular bonds of the waste are broken due to the high temperature in the container and elements. As a result of this process, the destruction of wastes and hazardous materials was found. Such waste disposal could provide renewable energy and other benefits.

Composting Project

Compost

Composting Project is a simple, natural biodegradation process that takes in organic waste, which is plant debris, garden, and kitchen waste, and turns it into nutrient-rich food for plants. Composting, commonly used in organic farming, occurs by leaving organic material in one place for months until microorganisms decompose.

Note that composting is often considered one of the best waste disposal methods because it can turn unsafe organic products into safe compost. However, this process has its drawbacks. Some people find it slow, while others find it takes up a lot of space. But despite these problems, many people are still using home composting to manage and reduce waste.

Conversion of waste to energy (Energy Recovery)

Waste to Energy, also widely recognized by its acronym, WtE, is generated by the waste in the form of heat or electricity.

The waste to Energy (WtE) process involves the conversion of non-recyclable waste into usable heat, electricity, or fuel through a variety of processes. This type of energy is renewable because non-recyclable waste can be used over and over again to produce it.

WtE can also help reduce carbon emissions by offsetting the demand for energy from fossil fuels. Over time, this will reduce global warming and improve our environment.

Special Waste Treatment

Some types of waste are considered dangerous and cannot be treated without special treatment, which will prevent contamination from occurring.

Biomedical waste is an example of such waste treatment. It is mainly used in medical institutions and similar institutions. Special waste treatment systems can effectively treat hazardous biomedical waste.

Avoid/minimize waste

The simplest method of waste management is to reduce waste generation, thereby reducing the amount of waste going into landfills.

Waste reduction can be achieved by recycling old materials such as cans and bags, repairing damaged items rather than buying new ones, avoiding the use of disposable products (such as plastic bags), reusing used items, and buying items with less design.

 

Best practices in waste management

Recycling and composting are two of the best methods of waste management. So far, composting has been done only on a small scale, either by individuals or in areas where waste can be mixed with cultivated soil or used for landscaping purposes.

On the other hand, recycling can be widely used all over the world, among which plastics, paper, and metals are the most recyclable items. Most recycled materials can be reused for their original purpose. In some cases, they may also be sold to generate profits.

The bottom line

As you can see, there are a number of important things you should know about waste Management plants to ensure that you and your environment are safe. While it may not be obvious, your choice paves the way for a better world and a healthier environment. This is why it is always sustainable and makes practical efforts to manage and dispose of waste. As we list a variety of waste management methods, please explore your options before making your final choice.

What Is Waste Management?

But what exactly is waste management? In the simplest terms, it can be defined as the collection, transportation, and disposal of garbage, sewage, and other waste.

Waste management plant

The waste management process involves handling solid and liquid waste. During the process, it also provides a variety of solutions for recycling items that are not classified as garbage. Therefore, the whole idea boils down to the reuse of waste as a valuable resource, and given our current environmental climate, this process is vital to all households and businesses.

You will find that there are eight main waste management methods, each of which is divided into many categories. These groups include source reduction and reuse, animal husbandry, recycling, composting, fermentation, landfill, incineration, and land use. You can start using many techniques at home, such as reduction and reuse, which can reduce the number of disposable materials used.

Benefits of waste management

There are multiple benefits to handling and managing waste. In this section, we will study them carefully.

Better environment

The biggest advantage of managing waste may ultimately lead to a better and fresher environment.

The waste disposal department also contributes to people's well-being by helping people get rid of diseases. The best part: all of this will happen, and unnecessary things should be handled in a proper, hygienic manner.

Multiple waste treatment units should be placed in the primary and secondary cities to prepare for the waste treatment process. In the long term, this will also help implement superior security measures.

Reduce pollution

If the waste is managed in the right way, not only can subsequent waste be eliminated, but also the impact and intensity of harmful greenhouse gases (such as carbon dioxide, carbon monoxide, and methane) that often seep out from accumulated waste in landfills can be reduced.

Waste management has reduced our dependence on landfills, while also greatly reducing many factors that have adverse effects on the environment.

Energy saving

Waste recycle is one of the biggest aspects of waste management, and it helps to save energy over time. One of the biggest examples of this advantage can be traced back to the practice of recycling paper.

All of us may know that thousands of trees are cut down to produce paper. When the waste paper is recycled to produce new paper, the need to cut trees has been greatly reduced. This helps save energy while reducing your carbon footprint.

Job creation

The recycling industry alone has created hundreds of jobs. As more and more people adopt this environmentally friendly approach, organizations that create and sell recycled products are at the forefront. This helped to promote its business development, while also creating hundreds of jobs.

Help make a difference

By managing waste, you can also bring changes to the entire society and the entire world. Although none of us can completely remove waste, we can always adopt environmentally friendly practices that reduce and reuse waste. In this way, you can create a role model for those around you who are now motivated to adopt sustainable methods.

Waste Treatment and Disposal Methods

 When people think of a waste treatment system, they may associate it with waste dumped into landfills or incinerated. Although such activities are an important part of the process, multiple factors are involved in creating the best integrated solid waste management (ISWM) system. For example, treatment technology can reduce the volume and toxicity of solid waste. These steps can transform it into a more convenient form of disposal. Choose and use waste treatment and disposal methods according to the form, composition and quantity of waste.

The following are the main waste treatment and disposal methods:

Heat treatment

Thermal waste treatment refers to the process of using heat to treat waste. The following are some of the most commonly used thermal waste treatment technologies:

Incineration is one of the most common waste treatment methods. The method involves burning waste in the presence of oxygen. This heat treatment method is usually used as a means of recovering electric energy or heating. This method has several advantages. It can quickly reduce the amount of waste, reduce transportation costs and reduce harmful greenhouse gas emissions.

Gasification and pyrolysis are two similar methods, both of which decompose organic waste by exposing the waste to a small amount of oxygen and a very high temperature. The pyrolysis process does not use oxygen at all, and there is very little oxygen in the gasification process. Gasification is more advantageous because it allows the combustion process to recover energy without causing air pollution.

Open combustion is a traditional thermal waste treatment method that is harmful to the environment. The incinerator used in this process has no pollution control device. They emit hexachlorobenzene, dioxins, carbon monoxide, particulate matter, volatile organic compounds, polycyclic aromatic compounds, and ash. Unfortunately, this method is still adopted by many local authorities internationally because it provides an inexpensive solution to solid waste.

Garbage dump and landfill

Sanitary landfills provide the most commonly used waste disposal solutions. These landfills hope to eliminate or reduce the risk of environmental or public health hazards caused by waste disposal. These locations are located where the land element acts as a natural buffer zone between the environment and the landfill. For example, landfills can be made of clay, which is very resistant to hazardous waste, or is characterized by no surface water bodies or low groundwater levels, thereby preventing the risk of water pollution. The use of sanitary landfills has the least harm to health and the environment, but the cost of establishing such landfills is relatively higher than other waste disposal methods.

Controlled landfills are more or less the same as sanitary landfills. These landfills meet many requirements as sanitary landfills, but may lack one or two. Such a dump may have a carefully planned capacity, but no unit plan. There may be no or no partial gas management, basic record keeping or regular cover.

The bioreactor landfill is the result of the latest technological research. These landfills use excellent microbiological processes to accelerate waste decomposition. The control function is to continuously add liquid to maintain the optimal moisture for microbial digestion. Liquid is added by recycling landfill leachate. When the amount of leachate is insufficient, liquid waste such as sewage sludge is used.

Biological waste treatment

Composting project is another most commonly used waste treatment method, which controls the aerobic decomposition of organic waste through the action of small invertebrates and microorganisms. The most common composting techniques include static composting, pest composting, composting composting and in-ship composting.

Anaerobic digestion plants also use biological processes to decompose organic matter. However, anaerobic digestion uses an anaerobic and bacteria-free environment to decompose waste, and compost must have air to allow microorganisms to grow.

There Are Four Ways to Deal With Waste

 You generate a lot of waste every week, but have you considered where the waste goes? Modern waste treatment methods provide you with multiple options to get rid of waste. China Recycling Sorting System supplier helps you find a solution that is both good for you and good for the environment.

Incineration

Incineration is an ideal way to describe burning waste as a method of disposal. This process generates heat, which is then used for energy. Incineration also produces by-products, including various gases and inert ash. The design of the incinerator and the burning waste determine the degree of pollution produced by this method. The filter can minimize contamination.

Incineration is economically better than recycling, because incineration of waste as an energy source is cheaper than recycling. But this is more expensive than disposing of garbage in a landfill. Incineration can reduce the amount of waste by up to 90% of the original amount. If the organic waste is incinerated, the ash produced can provide nutrients for the hydroponic solution. Incineration is the preferred method of processing toxic chemicals and hazardous waste.

Waste recycle

After the materials put into the recycling bin are processed and turned into new products or similar products, they have new uses. The most common recyclable items are plastic, paper, glass and aluminum. Recycling bins can be used in homes, offices or public places to collect recyclables before taking them to a recycling center. Many communities also offer curbside pickup of recyclable resources to make this choice easier. Recycling is the most environmentally friendly method because it does not add any waste. The disadvantage of recycling is that only certain items can be recycled, and the operation and maintenance costs of the processing plant are high.

Incineration

Compost

Composting is a natural process. Organic waste is decomposed into nutrient-rich compost, which is very suitable for your garden plants. When microorganisms are left in compost or trash bins for several months, they decompose. Composting projects retain more nutrients than incineration and are the preferred method of treating organic waste. The main disadvantage is the time it takes for organic materials to decompose into compost. This method also requires you to have enough space to pile up the compost, which will be a challenge if you live in a multi-family house or a small yard.

If you do not want to manage your own compost, please consult your local municipal service office. You can choose to pick up compostable materials on the side of the road. Separate trucks pick up these materials and take them to a facility where they are processed into compost. Check the list of allowable items to make sure you do not add items that cannot be processed as compost.

Sanitary landfill

Landfill is an option for items that you cannot remove through other methods. The protective lining under the waste helps prevent harmful chemicals from leaking into the groundwater and contaminating drinking water. The compacted waste is covered with a layer of soil. It is better to choose soil with low permeability for landfills to reduce the possibility of leakage. Some landfills use hardened materials such as cement or asphalt to seal each layer of waste. Landfills are usually located in areas where there is no flooding or high groundwater levels.

Fully Automatic Horizontal Hydraulic Baler

The fully automatic horizontal hydraulic baler is a mechanical and electrical integration and a very high degree of automation. It is mainly composed of mechanical systems, control systems, feeding systems, and power systems. The whole packing process consists of auxiliary time such as pressing, returning, carrying, transferring, outgoing up, outgoing down and receiving. Horizontal baler has the characteristics of good rigidity, toughness and stability, beautiful appearance, convenient operation and maintenance, safety and energy-saving, and low investment cost of equipment basic engineering. It is widely used in all kinds of waste paper factories, old waste recycling companies, and other units and enterprises. It is suitable for the packaging and recycling of old waste paper, plastic straw, etc. It is a money-making machine that improves labor efficiency, reduces labor intensity, saves manpower, and reduces transportation costs.

Brief description of the working process of the automatic horizontal hydraulic baler:

Horizontal detachable waste compress equipment is composed of 4 sets of wire devices installed on a frame. The entire wireframe is suspended on a central axis of the compression frame and is relatively compressed under the action of a hydraulic motor. The frame moves in the horizontal direction, and the compression frame is a welded component. The bottom is equipped with wheels, which can move horizontally along the main slide rail under the push of a hydraulic cylinder. The lifting platform is mainly formed by bolting two horizontal beams, and the lifting platform can move up and down in the vertical direction under the push of two hydraulic cylinders. The structure of the compression frame is basically similar to that of the compression frame, but there are 4 packing heads and 1 set of thread feeding devices arranged on it. The packaging heads of the waste paper hydraulic baler (4 in total) are the parts with the most complex structure and the most chained actions of the whole equipment. The packaging heads of each waste paper hydraulic baler have exactly the same structure and can be interchanged. There are 4 sets of thread feeding devices, each set corresponds to a packing head, and each set includes a packing line conveying device and packing line reverse tensioning device. The main rail seat of the waste paper hydraulic baler is mainly composed of two wear-resistant steel rails on the surface. The wheels of the compression frame are guided to run along the outer sides of the two tracks, and hydraulic cylinders that push the compression frame to run are arranged therein. In addition, there is a complete hydraulic station in addition to the mechanical components. It can be seen from the above description that various movements of the waste paper hydraulic baler are completed by fluid power.

Horizontal Baler

Use of automatic horizontal hydraulic baler:

The waste paper baler is used to squeeze waste paper and similar products under normal conditions and pack them into a special packaging tape to greatly reduce the volume, so as to reduce the transportation volume, save the freight, and increase the benefits for the enterprise. Used for packing loose materials such as waste paper (cardboard boxes, newsprint, etc.), waste plastics (PET bottles, plastic films, turnover boxes, etc.), straw, and other loose objects.
