Sources of waste can be broadly classified into four types: Industrial, Commercial, Domestic, and Agricultural.
- Industrial Waste. These are the wastes created in factories and industries.
- Commercial Waste. Commercial wastes are produced in schools, colleges, shops, and offices.
- Domestic Waste.
- Agricultural Waste.
Proximity principleThe transportation of waste can incur significant environmental and nuisance impacts plus unwanted additional cost. Therefore, the proximity principle encourages processing, recycling, reuse or disposal of waste as near to the point of its production as possible.

There are two main methods used in sanitary landfills, the trench method and the area method. This type of landfill collects household garbage and are regulated by state and local governments. The Environmental Protection Agency (EPA) has established minimum criteria that these landfills must meet.
Waste prevention, as the preferred option, is followed by reuse, recycling, recovery including energy recovery and as a last option, safe disposal. Among engineers, a similar hierarchy of waste management has been known as ARRE strategy: avoid, reduce, recycle, eliminate.
Plastic resin has limited value as a commodity because its quality degrades every time it is reheated. Consequently, most plastic is only reprocessed once before it goes to a landfill. “Downcycling” is a more accurate term than “recycling” when it comes to plastic. None of these products are in turn recyclable.
Here are some ways to manage waste properly.
- Source Reduction and Reuse. This is the strategy most commonly used by governments and local authorities.
- Recovery and Recycling. Recovery involves the use of discarded items for other meaningful uses.
- Landfills.
- Combustion/Incineration.
- Composting.
How do I practice waste management at home?
- Keep separate containers for dry and wet waste in the kitchen.
- Keep two bags for dry waste collection- paper and plastic , for the rest of the household waste.
- Keep plastic from the kitchen clean and dry and drop into the dry waste bin.
- Send wet waste out of the home daily.

The 7 Wastes of Lean
- Motion. Motion waste includes those movements (of machine or employee) which are more complicated or difficult than absolutely necessary.
- Inventory.
- Waiting.
- Defects.
- Overproduction.
- Transportation.
- Overprocessing.
5 Types of Waste; Do You Know Them?
- Liquid waste. Liquid waste refers to all grease, oil, sludges, wash water, waste detergents and dirty water that have been thrown away.
- Solid Waste. Solid waste is any garbage, sludge, and refuse found in industrial and commercial locations.
- Organic Waste.
- Recyclable Waste.
- Hazardous Waste.
Waste
- Waste (or wastes) are unwanted or unusable materials.
- Examples include municipal solid waste (household trash/refuse), hazardous waste, wastewater (such as sewage, which contains bodily wastes (feces and urine) and surface runoff), radioactive waste, and others.
When speaking about waste, lean experts usually refer to seven specifically. These include: transportation, inventory, motion, waiting, over processing, overproduction, and defects.
When categorizing hazardous waste, the EPA breaks it down by four characteristics:
- ignitability, or something flammable.
- corrosivity, or something that can rust or decompose.
- reactivity, or something explosive.
- toxicity, or something poisonous.
Refuse, also called municipal solid waste, nonhazardous solid waste that requires collection and transport to a processing or disposal site. Refuse includes garbage and rubbish. Trash, especially electronic waste, may require special collection and handling.
"Domestic waste" means any nonputrescible waste, consisting of combustible materials, such as paper, cardboard, yard clippings, wood, or similar materials, generated in a dwelling, including the real property upon which it is situated, containing four living units or less.
Top 10 Most Important Items to Recycle
- ALUMINUM. Aluminum cans are 100 percent recyclable, and they can be recycled over and over again.
- PET PLASTIC BOTTLES.
- NEWSPAPER.
- CORRUGATED CARDBOARD.
- STEEL CANS.
- HDPE PLASTIC BOTTLES.
- GLASS CONTAINERS.
- COMPUTERS.
The first step is collection. Materials are taken from the curbside or drop-off center. The second step is processing and marketing of recycled materials. Materials are sorted and then sold.
Upcycling, also known as creative reuse, is the process of transforming by-products, waste materials, useless, or unwanted products into new materials or products perceived to be of greater quality, such as artistic value or environmental value.
Plastic recycling process
- Step 1: Collection. The first step in the recycling process is always collecting the plastic material that is to be recycled.
- Step 2: Sorting.
- Step 3: Washing.
- Step 4: Resizing.
- Step 5: Identification and separation of plastics.
- Step 6: Compounding.
Ultimately, you are the first (and arguably most important) step in the recycling process. Without you tossing those discarded materials in the recycling bin, there would be no material to sort.
Types of Recycling
- Waste Paper and Cardboard. Recycling paper is vital to ensure you reduce your environmental impact and reduce general waste.
- Plastic Recycling.
- Metal Recycling.
- WEEE Recycling (Electronic Devices)
- Wood Recycling.
- Glass Recycling.
- Clothing and Textile.
- Bricks and Inert Waste Recycling.
Recycling includes the following four steps:
- Step 1: Collection. There are several methods for collecting recyclables, including:
- Step 2: Processing.
- Step 3: Manufacturing.
- Step 4: Purchasing Recycled-Content Products.
- Sorting. The process of recycling starts with sorting the paper.
- Transporting. The papers are then tied and transported to warehouses for storage.
- Pulping. The pulper is a large vat that has chemicals and water.
- Screening. The mushy pulp is then screened.
- Cleaning.
- De-Inking.
- Washing.
- Bleaching.
Those are the two primary means of waste disposal in the United States: landfill and incineration.
