You were introduced to the main types of liquid waste in Study Session 1. This study session is the first of three that builds on that introduction and describes liquid wastes in more detail. We begin with a closer look at the sources and characteristics of liquid wastes.

16 Major Classification of Solid Waste | Solid Waste Management

Study Session 5 focuses on the different types of latrine available for urban areas in Ethiopia. In Study Session 6 you will learn about the management and treatment of liquid wastes. The type and composition of liquid waste depends on the source. In urban areas, the main sources are households, commercial establishments and industries.

We need accurate information on the characteristics of liquid wastes in order to establish proper waste management processes to deal with them. In this study session you will learn about the main sources of liquid wastes and about different ways of characterising them. We also briefly describe some of the laboratory tests used to analyse liquid waste. The session ends with some specific examples of liquid wastes from industry.

Search OpenLearn Create.Sources of waste Municipal sources of waste: This includes trash or garbage from households, schools, offices, market places, restaurants and other public places. They include everyday items like food debris, used plastic bags, soda cans and plastic water bottles, broken furniture, grass clippings, product packaging, broken home appliances and clothing.

They tend to be classified as hazard waste rather than general waste. Items in this group include surgical items, pharmaceuticals, blood, body parts, wound dressing materials, needles and syringes. Agricultural sources of waste: Typically, this is waste generated by agricultural activities. These include horticulture, fruit growing, seed growing, livestock breeding, market gardens and seedling nurseries. Waste items in this group include empty pesticide containers, old silage wrap, out of date medicines and wormers, used tires, surplus milk, cocoa pods and corn husks.

End-of-life Automobiles: When cars are all old and not working again, where do they end up? Many people just leave them to rust in the fields, but there is a better way to deal with them. In many cities, these vehicles are sent to the plant, where all the removable parts are taken out for recycling. The rest is flattened up and shredded into peices for recycling. The last bits that cannot be used again is sent to a landfill.

Industrial sources of waste: Since the industrial revolution, the rise in the number of industries manufacturing glass, leather, textile, food, electronics, plastic and metal products has significantly contributed to waste production.

Take a look at the things in your home, every item there was probably manufactured and possibly, waste was produced as a result.

Study Session 4 Liquid Wastes: Sources, Types and Characteristics

Sometimes old buildings and structures are pulled down demolished to make space for new ones. This is particularly common in old cities that are modernizing. This is called demolition waste.

Waste items include concrete debris, wood, earth, huge package boxes and plastics from the building materials and the like. Electronic sources of waste: This is waste from electronic and electrical devices. Think of DVD and music players, TV, Telephones, computers, vacuum cleaners and all the other electrical stuff in your home. These are also called e-waste, e-scrap, or waste electrical and electronic equipment WEEE Some e-waste like TV contains lead, mercury, cadmium, and brominated flame retardants.

These are harmful to humans and the environment. It is therefore important that the right authorities ensure the proper disposal of such waste. All Rights Reserved.

It could be in the form of Bones Other parts of animals they slaughter Wood With the progress of civilization the waste generated became of a more complex nature. The existing landfills are neither well equipped or well managed and are not lined properly to protect against contamination of soil and groundwater.

Hazardous wastes could be highly toxic to humans, animals, and plants. They are Corrosive Highly inflammable, or explosive React when exposed to certain things e. These chemicals include formaldehyde and phenols, which are used as disinfectants. Direct exposure to chemicals in hazardous waste such as mercury and cyanide can be fatal.

According to USEPA, hazardous waste is defined as any solid, liquid or gaseous substance which, by reasons of any physical, chemical, reactive, toxic or infectious characteristics, causes danger to health or environment when improperly treated, stored, transported or disposed off. Sources of hazardous wastes include industries, petroleum refineries, transportation, coke-ovens, blast furnace sludges, scrubbing sludges and biological waste generating laboratories, thermal and nuclear power plants and nuclear reactors etc.

A simple approach to classify hazardous wastes is to consider these wastes into general categories such as toxic, inflammable and radioactive etc. Such a classification system helps the fire service to properly deal with the hazardous wastes under emergencies.

Many countries e. However, in Japan, the four types of wastes viz. The best way to classify the hazardous wastes is on the basis of algorithms that consider toxicity corrosivity, persistence, inflammability, quantity of waste involved, the extent of hazard to the environment and ultimate effects on living organisms. The term solid waste includes semi-liquids, liquids and contained gaseous materials as well.

This stipulation is applicable to the wastes that are stored or treated prior to disposal but not to those to be recycled. For instance, municipal solid wastes, agricultural wastes and animal manures are excluded. That is, whether it has the potential to increase the mortality or illness or whether it poses a substantial threat to human health or environment on the basis of hazardous characteristics such as corrosivity, inflammability, toxicity or explosiveness.

As regards the hazard to health or the environment, the following standard tests quantified by EPA are considered:. As far as toxicity to the ground water is concerned, the 14 contaminants viz.

Wastes which are known to be hazardous carcinogenic and mutagenic etc. The main objective of hazardous waste management plan is to eliminate or reduce the hazardous waste through process changes or resource recovery. The waste must be accounted for from its origin to ultimate disposal. This cradle to grave concept is followed by USA and Canada. All the industries producing more than kg of hazardous wastes per month should be registered. An inventory of such waste generating agencies and the quantity of waste produced per month should be prepared.

The hazardous waste generating plants should equip themselves with special on-site tanks, chemically resistant containers or basins for storage of waste. The wastes must be transported by suitable tanker trucks, flat-bed trucks or rail cars of the approved disposal sites. A well publicized emergency plan should be prepared to deal with unexpected spillage or accidental release of contaminants during transport to prevent environmental damage and public health hazard.

The wastes should be transported to a physical and chemical treatment plants for processing or concentration or hauled directly to an approved hazardous waste treatment facility for final disposal. When on-site recycling or recovery of waste is not feasible, the possibility of waste exchange should be explored. Transferring wastes from large industries to smaller ones which are able to reuse low purity oils, acids, alkalies, solvents or recover valuable metals and other materials from concentrated wastes, can also be considered.
