Processed waste materials

Types of processed waste materials

Generally, the types of processed waste materials are differentiated according to their physical and geometrical characteristics, including shape, size, color, and structure. They can be categorized into fibers such as waste paper and plastics, and particles such as wood chips, sawdust, and coarsely crushed and finely—ground waste glass, as well as granules like sand, cork granules, rubber granules, etc. Additionally, there are also waste ceramic particles, metal waste, and e-waste that are distinguished according to chemical compositions and contaminants.

Processed waste materials can also be categorized according to the properties and potential uses of the materials. They may include inorganic materials like waste glass, waste ceramics, waste metals, and sand; organic materials such as fibers from the pulp of trees used for paper, wood chips, sawdust, plastic particles, rubber granules, and cork granules; and compound materials like composite materials that are mixed with different types of plastics and rubber.

Furthermore, processed waste materials are also classified according to their environmental impact. They may include renewable raw materials, which are resources that can be regrown or remanufactured for reuse, such as waste paper, waste glass, waste ceramics, wood chips, and rubber granules, etc. that can be recycled; non-renewable raw materials, such as metal waste, that can only be used once; harmful wastes like e-waste that contain toxic substances and may cause damage to both nature and humanity.

Additionally, according to waste management methods, processed waste materials can be classified into recycled materials, which are resources that have undergone reprocessing so as to be reused again, such as waste paper, waste plastic bottles, waste glass bottles, cork granules, rubber granules, etc.; incineration residues, which refer to those that are incinerated to reduce volume and produce energy; landfilling materials are those that are no longer recyclable and are disposed of and landfills.

Specification and Maintenance of Processed Waste Materials

Some important specifications and details for waste processing machines include the capacity, feeding method, and output.

• Capacity: The amount of waste a machine can handle is usually given in kg or tons per hour. For small shredders or crushers, the capacity may be around 50-200 kg per hour. Bigger industrial machines can process 500-2000 kg of waste per hour. The exact capacity depends on the machine's size and power.
• Feeding Method: Machines can have different ways to put in waste. A manual hopper means workers load waste by hand into a open top. Conveyor belts are used to scoop waste from other processes. Some machines have large chutes that waste falls into from pipes or ducts. Chutes allow larger amounts of waste to be fed in continuously.
• Output: After processing, waste material comes out in different forms. Shredders and crushers reduce waste into small pieces. The small pieces are usually stored in bins. Screens separate fine material that falls through the screen from bigger pieces that are directed out the side. Conveyors move sorted materials to storage areas or bins. Bins usually have labeled names for specific materials like plastic, paper, metal, etc.

Maintenance

It is very important to keep waste disposal machines running well by doing regular maintenance. Some key maintenance tips are as follows:

• Machines should be inspected every week for loose bolts, damaged parts, and worn belts. Bolts should be tightened, and any damaged or worn parts should be fixed or replaced.
• Look carefully at the blades and screens to see if they are worn from use. Blades chop waste and screens sort materials, so they inevitably wear down. Sharp blades make cleaner cuts. Screens can become full of debris. Both need periodic checking and cleaning or replacing as needed.
• Belts that move materials around should be checked for wear, tearing, or damage. Adjust the tightness of belts so they are not too loose or tight. Properly adjusted belts prolong life and reduce breakdowns.
• Oil and grease pump bearings and other moving parts as recommended by manufacturer scheduler lubricate only. This prevents excess build-up of grease.
• Trim any belt covers that have debris buildup to prevent excessive over heating of the motor that drives the belts. Only removed parts that need trimming.

Scenarios

Industries make use of processed waste materials in various ways. Here are some of them.

• Construction Industry

  Processed waste materials like plastic bottles, which are reprocessed into fibers, and glass fragments, known as cullet, are used as reliable construction materials. For instance, recycled plastic is used to produce strong building insulation, while glass cullet is frequently used in asphalt for road construction or insulation for building materials.

• Landfills

  Landfills have incorporated processed materials to decrease the volume of waste that must be landfilled. For instance, shredded tires, sometimes referred to as liquid tire technology, are used as an alternative lightweight fill material. They take up less space than regular landfill fill does.

• Composting

  Composting facilities may further process food waste, relying on specialized machinery to transform organic waste into nutrient-rich soil additives by accelerating the natural decomposition process with heat, moisture, and microbial activity.

• Investment Firms

  Firms that invest in the further processing of recycled materials for multiple uses stand to gain financially. Companies that are seeking to invest more in processed waste material turnaround facilities could partner with multinational companies to collect, transport, and supply raw material to developed industries that make further use of the waste material.

• Manufacturing Industry

  Manufacturing facilities utilize processed waste materials as raw materials in different production processes to create new products. For example, recycled paper and cardboard are repulped and processed to manufacture new paper products, thereby closing the loop in paper waste recycling.

  Similarly, recycled plastic is extensively used to manufacture packaging materials, containers, and even automotive parts.

• Biomass Energy Plants

  Biomass energy processing plants utilize wood chips and other organic waste byproducts as valuable sources of energy. These materials are processed and converted into heat or electricity through combustion or anaerobic digestion, thereby contributing to sustainable energy production.

• Agricultural Industry

  Agriculture industries use manure and processed food makes as fertilizers on farms. These are further processed into high-quality organic fertilizers by undergoing natural decomposition or fermentation, enriching soil fertility and promoting sustainable farming practices.

How to Choose Processed Waste Materials

• Data Analysis of Processed Waste Material:

  Before investing in waste processing equipment, it is crucial to research and analyze the data regarding recently utilized or in-demand waste material processing machinery to acquire sufficient and useful information.

• Focus on a Specific Waste Material:

  A plethora of industrial-scale waste processing machines are available to cater specifically to distinct waste materials. It is essential to concentrate on a particular waste material, such as plastic, food, e-waste, rubber, etc., and subsequently choose a machine that is capable of efficiently processing that specific type of waste.

• Evaluate the Processing Capacity:

  Waste disposal is an extremely time-consuming and labor-intensive task. Furthermore, the enormity of the environmental crisis demands rapid and efficient solutions to curb it. The processing capacity of machines indicates the rate at which waste materials can be transformed or repurposed. It is essential to select machines that possess a high processing capacity to facilitate timely and effective waste management.

• Consider the Type of Treatment:

  From recycling and composting to incineration and landfill, there exist several waste disposal methods. Different types of waste processing machines are designed to carry out distinct treatment methods. It is imperative to select the appropriate machine according to the desired treatment method.
