classification of waste
Twomainwastecategoriescanbeestablishedbasedonthedistinctlegislationandpolicy
instrumentsusuallyinplace:
•non-hazardousorsolidwaste
•hazardouswaste.
•Non-hazardous/solidwasteisallwastewhichhasnotbeenclassifiedashazardous:

•Hazardouswasteiswastethathasbeenidentifiedaspotentiallycausingharmtothe

themaincharacteristicsofhazardouswaste.
•E-wasteis waste from electric and electronic equipment such as end-of-life computers,
phones and home appliances. E-waste is generally classified as hazardous because it
contains toxic components (e.g. PCB and various metals).
•Medical wasteoriginates from the human and animal healthcare systems and usually
consists of medicines, chemicals, pharmaceuticals, bandages, used medical equipment,
bodily fluids and body parts. Medical waste can be infectious, toxic or radioactive or
contain bacteria and harmful microorganisms (including those that are drug-resistant).
•Radioactive wastecontains radioactive materials. The management of radioactive waste
differs significantly from that of other waste. Auditing the management of radioactive
waste is not the subject of this MOOC.

Characteristic of Waste
1. Ignitability
Any waste that is flammable and can create fires. Examples of this include
liquids with flashpoints below 140 °F, nonliquids with the potential to ignite via
specific conditions and compressed gases.
2. Corrosivity
Any waste (typically acids and bases) that can rust and decompose and has the
ability to melt through steel materials. Examples of this include aqueous wastes
with an acidity level of equal to or less than 2 pH or equal to or greater than 12.5
pH.
3. Reactivity
Any waste that is explosive, unstable under normal conditions. Examples of this
include any waste capable of explosion and detonation that may produce toxic
gases.
4. Toxicity
Any waste that is fatally poisonous when ingested or absorbed. Examples of this
include lithium-sulfur batteries and other materials that can cause death when
swallowed.

HOW TO HANDLE THE WASTE
SASIKUMAR NATARAJAN -EDUCATIONALIST & HOSPITALITY TRAINER

SASIKUMAR NATARAJAN -EDUCATIONALIST & HOSPITALITY TRAINER
1. Evaluate your waste–to be able to handle the waste properly, the
company first needs to determine whether the waste is hazardous or not,
and whether handling of that particular waste is regulated by legislation.
This step is often called classification or categorization of the waste.
2. Store your waste–depending on the type of waste, there will be different
requirements in terms of storage facilities. Waste can be in solid or liquid
form, so it is important to store it according to its characteristics. Hazardous
waste must be stored in a sturdy, leak-proof container that is kept closed
when not adding or removing waste.
3. Label the waste–nonhazardous waste doesn’t have to be labeled in any
special way. On the other hand, hazardous waste labeling is often prescribed
by law and in most countries, the company must obtain a license for even
generating some kinds of hazardous waste. The label for marking packed
hazardous waste usually contains the following information:
•Warning: HAZARDOUS WASTE

Required Equipment
Few important equipment needed to run a successful waste management business.
Followinglist of important tools and equipment that are needed:
1)Waste Collection Truck: You can either use a second-hand van or truck or buy a new
one to transport client’s waste to recycling or disposal facilities. To save money, you can also
opt for a rented junk removal truck instead of buying a new one initially. The truck should
have a large load capacity and good fuel economy.
2) GPS System: For those who do not have a smartphone or are unfamiliar with your service
area’s layout, you would also need a reliable GPS system.
3) Heavy Duty Work Wears: To remove dirt and garbage, you would need durable work
clothes, gloves, and rubber boots. Loose fitting trousers are suited for both indoor and
outdoor jobs and are also comfortable. Clothes should be such that they prevent household
and garden pests from biting you.
4) Shovel and Rake: These are needed to remove dirt, leaves, sand and other debris.
5) Heavy-duty Protection: These include facial masks and goggles, dirt and product
separator to prevent any contamination from dust and dirt.
6)Incinerators, trash cans, dustbins, and waste bags.
7)Hose and pipes for the continuous supply of water.
