Waste

Non-liquid, non-soluble materials ranging from municipal garbage to industrial wastes that contain complex and sometimes hazardous substances.

Solid wastes also include sewage sludge, agricultural refuse, demolition wastes, and mining residues.

Technically, solid waste also refers to liquids and gases in containers

Waste: Any material that is discarded, served its intended purpose, or is a manufacturing or mining byproduct

Solid Waste: Everything not covered by the Clean Air and Water Acts, including solids, liquids and gases (RCRA is a catch all)

What is Solid Waste

Solid waste means any garbage, refuse, sludge from a wastewater treatment plant, water supply treatment plant, or air pollution control facility and other discarded materials including solid, liquid, semi-solid, or contained gaseous material, resulting from industrial, commercial, mining and agricultural operations, and from community activities

Solid wastes are any discarded (abandoned or considered waste-like) materials. Solid wastes can be solid, liquid, semi-solid or containerized gaseous material.

In Simple Words

waste tires septage scrap metal latex paints furniture and toys domestic refuse (garbage) discarded appliances and vehicles uncontaminated used oil and anti-freeze empty aerosol cans, paint cans and compressed

gas cylinders construction and demolition debris, asbestos

Examples of solid wastes:

Environmentally acceptable disposal of waste on ground. 

Sanitary landfills are where non-hazardous waste is spread in layers, compacted, and covered with earth at the end of each working day. Secure landfills are those where hazardous waste is disposed of by burial, in holes or trenches in ground lined with impervious plastic sheeting to prevent leakage or leaching of dangerous substances into soil and water supply.

What is Landfill

Waste Busters Lahore

Transfer Station/Disposal Site

Protect human health and the environment from the potential hazards of waste disposal

Conserve energy and natural resources

Reduce the amount of waste generated

Ensure that wastes are managed in an environmentally sound manner

Resource Conservation and Recovery Act

Hazardous Waste: manages hazardous waste from the time it is generated until it is disposed (referred to as cradle to grave)

Solid Waste: sets criteria for municipal solid waste and other non-hazardous waste disposal facilities and prohibits open dumping of solid waste

Underground Storage Tank: regulates underground storage tanks storing petroleum or other hazardous substances

Landfills

Waste Management and Remediation Division is responsible for monitoring and controlling the generation, treatment, storage, and disposal of wastes. On the remediation side, program resources are directed to responding to releases of hazardous substances to surface waters, ground water, or soils.

Waste Management & Remediation

Waste remediation is a process in which contaminants are removed or neutralized so that they cannot cause harm. It may entail actively removing the waste, which is generally preferable, or isolating or containing the waste on-site because it too costly or impractical to remove.

Light Weighting

The process of reducing the amount of a particular material per unit of product is known as light weighting

Where does our trash go?

In 2007 almost 65% of the solid wastes produced in U.S. went to 2,500 sanitary landfills.

Landfilling Landfilling is the term used

to describe the process by which solid waste and solid waste residuals are placed in a landfill

Waste dumps or uncontrolled land disposal sites

Secure landfills for Hazardous Waste

a) After geo-membrane liner has been installed

b) After two lifts of solid waste

c) Landfill with final cover

burn more than 50% of their trash.

Storage tanks are used to store petroleum or certain other hazardous liquids. Leaking USTs can pose a serious environmental threat if the stored petroleum or other hazardous substance seeps into the soil and contaminates ground water, which is the source of most drinking water.

For a Cleaner Tomorrow

Recycling is the process of transforming waste materials into usable resources. It is preferable to treatment and disposal because it helps conserve energy and reduce waste. Recycling, like garbage collection, is an optional service provided at the discretion of local governments or by private recycling companies.
