Convectional rainfall occurs in equatorial area. In this areas, the surface gets heated because of the sun's heat and the air near it also get heated. As it get heated, it spreads and becomes lighter and moves upwards. Condensation of the water vapour takes place and results in rainfall. In equatorial areas such type of rainfall occurs daily.

 Micro-chemistry, substitution with a non-hazardous substance and using chemical exchange program can be used to reduce the amount of hazardous waste except mixing hazardous with non-hazardous waste to dilute the mixture.

Waste is segregated into dry, wet and hazardous categories by using different dust bins for different wastes.

Dry waste includes wood and related products, metals and glass etc.

Wet waste typically refers to the wastes that contain moisture or wetness. These are heavy in weight due to dampness.

Hazardous waste include biomedical wastes like pathogen infected needles, radio-active chemicals and explosive wastes.

Containers should be labeled as soon as the first drop of waste is added to the container.

E-Waste describes discarded electronic devices. Used electronics which are meant to be recycled are also included in this category. Used computers, office electronic equipment, entertainment device electronics, mobile phones, television sets, and refrigerators are the examples of e-waste

E-waste contain lead, cadmium, beryllium etc. which are potentially harmful. Recycling and disposing of e-waste poses a high risk to the workers. 

Biomedical waste includes used menstrual cloth, sanitary napkins, disposable diapers, bandages and any material that is contaminated with blood or other body fluids.

Medical wastes are classified as infectious wastes and non-infectious waste. Most of the biomedical waste is toxic in nature.

Non-infectious waste: It is not harmful and do not result in spread of any infection. Examples include: catheters, colostomy bags etc.

Infectious waste: Needles with pathogens, blood containing swabs etc. are the source of infections.

The maximum amount of hazardous waste that can be held in a satellite accumulation site (excluding acutely hazardous waste) would be 55 gallons.

Hazardous wastes are wastes with properties that make them dangerous or potentially harmful to human health or the environment. Hazardous wastes  can be liquids, solids, contained gases, or sludges.

When labeling a vessel that contains hazardous waste one must list all hazardous components and their concentrations.
