➢ The most important biological characteristic of the organic fraction of MSW is that almost all the organic components can be converted biologically to gases and relatively inert organic and inorganic solids.
What is biological solid waste?
Biological waste is any material that contains or has been contaminated by a biohazardous agent. Biological waste includes, but is not limited to; Petri dishes, surgical wraps, culture tubes, syringes, needles, blood vials, absorbent material, personal protective equipment and pipette tips.
What is characterization of solid waste?
Waste characterization means finding out how much paper, glass, food waste, etc. is discarded in your waste stream. Waste characterization information helps in planning how to reduce waste, set up recycling programs, and conserve money and resources.
What are the characters of solid waste?
The chemical properties of solid waste are composed of moisture content, volatile solid, ash content, CHNSO contents, calorific value and heavy metal.
Which is the physical characteristic of solid waste?
The physical parameters of MSW characterised are: particle size distribution, geometry and classification of the waste, moisture and organic matter content, unit weight, and temperatures of the landfilled waste.
What are the biological treatments for solid waste?
These may include separation, shredding and crushing of the material. The biological operations include composting and anaerobic digestion. The composting can take place in heaps or in composting facilities with optimisation of the conditions of the process as well as filtering of the produced gas.
How biological waste are disposed?
Biological liquid waste can be poured down the drain (sanitary sewer), under running water after it has been decontaminated by autoclave or chemical means. Human or animal blood and body fluids do not need to be disinfected before being poured down the drain.
What are the characteristics of waste?
Characteristic wastes are wastes that exhibit any one or more of the following characteristic properties: ignitability, corrosivity, reactivity or toxicity.
What is waste analysis and characterization?
Waste Analysis and Characterization Study (WACS) is the process of gathering information on the quantity (such as tons per day, cubic meter, per day and kilograms per household/day) and composition (such as biodegradable and non-biodegradable) of solid wastes generated from various sources.
How do you characterize hazardous waste?
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.
What are the different sources and characteristics of solid waste?
Residences and homes where people live are some of the major sources of solid waste. Garbage from these places include food wastes, plastics, paper, glass, leather, cardboard, metals, yard wastes, ashes and special wastes like bulky household items like electronics, tires, batteries, old mattresses and used oil.
What are the characteristics of liquid wastes?
1 Physical characteristics of liquid wastes. Wastewaters may contain particles of solid material carried along in the flow. These may be settleable solids or suspended solids. Settleable solids sink to the bottom (settle out) when the speed of flow is reduced, for example, when the wastewater is stored in a tank.
What is physical waste?
Physical waste. Physical construction waste is defined as waste which arises from construction, renovation and.
