Waste Management can be defined as the process of collecting, processing, recycling and controlling any material considered as waste.

Improperly disposed waste litters on road sides, in land fills, gutters and ditches. They are generally bad for the following reasons:

• The waste block drainages hence resulting to flooding, especially during the rainy seasons.
  Please read on erosion here.

• They generate bad smells which can be dangerous to health.

• They constitute nuisance and eyesore.

• They become homes to various disease causing organisms.
  Please read on vectors of diseases here.

Wastes can be classified into various types. These are:

• Biodegradable waste

• Non-Biodegradable waste

• Refuse

• Sewage

• Recyclable waste

• Electronic waste

• Green waste

• Biomedical waste

• Metabolic waste

• Radioactive waste

Disaccharides are composed of two monosaccharides joined together; thus are also referred to as double sugars.

Disaccharides are often added as sweeteners to food; for instance, the table sugar called sucrose is a disaccharide often used by us to sweeten our tea.

Maltose is another disaccharide used as an ingredient for making malt drinks, chocolates and candies.

The breast milk contains the disaccharide -> lactose.

Lactose is very vital for the normal growth and development of infants.

In adults, disaccharides are non essential nutrients. This implies that we can live without them as adults.

Below is a summary of monosaccharides that make up disaccharides (double sugars).

• Maltose = Glucose + Glucose

• Lactose = Glucose + Galactose

• Sucrose = Glucose + Fructose

Other examples of disaccharides include trehalulose and isomaltulose

Polysaccharides are complex sugars. These are what we often eat whenever we eat carbohydrates.

We have four types of polysaccharides namely:

1. Starch

2. Glycogen

3. Chitin

4. Cellulose

Starchy foods include rice, cassava and yam.

Glycogen is stored in the human liver; as a result of the joining of many glucose molecules.

Chitin is a major component of insect and anthropod's skeleton.

Cellulose is a major component of a plant's cell wall. They cannot be digested when eaten by humans; hence they function as roughages.

Roughages are not classified as one the classes of food in humans. This is due to the fact that they aren't digested. They will rather facilitate the movement of bowels in the large intestine (colon). For this reason, they can be very useful in treating constipation.
