Significance / Importance of Manufacturing Industry
1. It provides employment
2. Diversification of the economy; Industries reduce the reliance on one type of product
3. Earning of foreign currency example Germany earns foreign currency because of exporting the manufactured products
4. It leads to self-sufficiency. The country reduces its reliance on imported goods hence its economy becomes stable
5. Development of transport and communication like roads railway lines, ports etc
6. It encourages improvement of social services
7. It reduces expenses on imports
Types of Manufacturing Industries
Manufacturing industries are divided into processing and fabrication industries.
1. Processing industries are the ones which deal with preparing the raw materials for fabrication. For example coffee pulping, decorator and cashew nuts hullers
2. Fabricating industries are the ones that deal with making new products from the processed materials for example textile industry.
Manufacturing industries can also be classified as heavy industries or light industries:
1. Heavy industries are industries which involve the production of bulky and heavy products like iron and steel industry, car assembling and shipping etc
2. Light industries are those which involve the production of light and complex products for example the manufacture of plastics, textiles, cosmetics and paper
Factors Influencing the Location of Industries
These are several factors which combine to influence the location of industries these include:
1. Availability of raw material. Some industries are located near to the source of raw materials, for example most of the processing industries and food manufacturing industries
2. Fuel and power availability. For example location of iron and steel industries in United Kingdom and china
3. Human resources. This helps to the labour supply both skilled and unskilled
4. Availability of capital. This is needed for the investment in the machinery and importation of raw materials
5. Market availability.
6. Industrial inertia and historical factors Industrial inertia is the tendency of old industries to remain in the same area without shifting to the new area. Despite of unfavourable conditions these industries continue being in the same area because of the well-established transport system and assured supply of labor as well as social services supply.
7. Availability of transport and communication systems.
8. Government policies. This helps on balancing the economic development of a certain area and provision of jobs
9. Government stability. Is the ability of government in maintenance of peace of a particular place.
Effects of the Manufacturing Industries on the Environment
1. Mining leads to environment pollution, that is water pollution, air pollution, soil pollution and noise pollution.
a) Air pollution which caused by the introduction of greenhouses gases like carbon dioxide and nitrogen oxide.
b) Water pollution caused by introduction of hot water and chemicals from the industries,
c) Soil pollution due to dumping radioctive materials on the soil
d) Noise pollution due to loud voice from the industries which can disturb the people.
2. Mining causes land dereliction (exhaustion), this destroys the nature of the landscape and leads to mineral resources exhaustion.
3. It accelerates deforestation as a result of clearing of vegetation so as to eastablish the mining centers and settlement.
4. The size of the land is reduced and the soil structure and texture are destroyed because of the mixture with fragments of rock and hence plant growth can not take place easily.
5. Mining leads to the disappearance of valuable plant species
6. Greenhouse effect and global warming can occur as a result of energy generating minerals like coal, uranium etc.
7. The pits which are flooded with water act as mosquito breeding places and hence accerate the spread of malaria.
8. Positive effects involve the use of virgin land which was once useless
Types of Pollutants
a) Gaseous pollutants; Are the pollutants which occur in gaseous form. These include greenhouse gases like carbon dioxide, carbon monoxide, nitrogen oxide etc which pollute the air. These pollutants on polluting the air lead to the formation of acidic rainfall and global warming. Acid rainfall leads to the addition of acid in the soil which in turn causes the death of plants and microorganisms as well as destruction of buildings by removing the paint on the walls.
b) Particulate dust matter and other solid matter Are the pollutants which occur in particle or solid which emirates from the industries get into the air or water bodies or soil and cause contamination. These can lead to the increase in acid or toxicity in places where they can be dumped
c) Liquid matters; this includes all forms of molten or semi molten materials (liquid). These involve hot water and chemicals from industries. Hot water leads to thermal pollution of water bodies which can kill the aquatic animals/organisms because of the sharp rise in temperature

| Air Pollution |
General Effects of Industrial Pollutants on the Health of an Individual Employee and Communities living around
1. Water pollutants cause disease like Cancer, Typhoid, and diarrhea.
2. Air pollution can lead to respiratory diseases like bronchitis to employees and people around.
3. Soil pollution can cause decline in agricultural production and hence lead to starvation to take place
4. People are also affected by noise and sometimes can lead to problems in the blood circulation. For example Blood pressure and heart attack.
Ways of Reducing Pollutants
1. The combustion system in the engines should be filled with efficient facilities so that the amount of greenhouse can be reduced if not solved totally.
2. The industries should be located far away from the residential areas.
3. Recycling the wastes for example the metal materials should be recycled so as to reduce wastes
4. There should be other activities developed so as to avoid over dependency on manufacturing industries only especially in Japan etc. other materials.
5. To avoid noise pollution the parts of the engine should be lubricated and materials used should be like bronze which does not make noise.
6. There should be concerted efforts by the government and non-governmental organizations and some committed individuals in certain environmental pollution.
7. There should be strong policies governing the industrial operations and ensuring that people who invest in industrial operations /development are given proper education on how to handle the waste products properly i.e. recycling
8. The industrial wastes should be treated to render them harmless to the health of people.
9. Alternative energy sources which are environmentally friendly like solar energy, natural gas, wind power etc.
