Impact Of Plywood On The Environment

pic-environment02 (1)There are two kinds of environmental impacts created by plywood industries. They are the offsite and onsite impacts. When the impact is the area where the manufacturing takes place, it is called onsite impact. The impact caused associated with timber harvesting, which is used as the source in plywood industry is the offsite impact.

Onsite impacts
The plywood industries, like most of the industries, causes water, noise, soil and air pollution. Its energy consumption and transportation carry a great carbon footprint.

Water pollution
Leaching timber for tannins, leakage from chemicals and other fuels are the major reasons for water pollution. This run off can pollute both ground water by infiltration and surface water that is near the industry. The main chemicals that are used in plywood industry are urea and formaldehyde. These chemicals pollute the water which makes it unfit for consumption. Also, if the water is chlorine treated to purify it, it forms carcinogens.

Most of the plywood industries are built in rural areas which make the noises even more noticeable. The main reasons for noise are transported finished products and raw material, the noise made by peeling machine and generators.

Soil pollution
Organic substances that leach from timber, sawdust and bark and other chemicals pollute the soil surrounding the industry. If not properly contained, it could affect the soil quality in the surrounding communities.

Air pollution
Air pollution is caused by the emission of chemicals, particulate emission from wood sawing and hydrocarbon from generators. The key pollutants of air are formaldehyde, methanol, saw dust and hydrocarbons.

The other environmental impacts include deforestation, soil degradation, carbon footprint, and disposal. When timber is harvested for plywood manufacture, there is severe deforestation. As a result of deforestation, the top soil is lost in run off during monsoon, resulting in degradation. Carbon footprint is also high, due to the transport of products and raw materials. Plywood disposal is a huge concern as it takes 20 years to decay, and recycling does not provide any useful product. Burning releases pollutants and hence, disposal of plywood is fairly difficult.

Street Cleaning And River Pollution Discussed

2014-09-02-nutrient-sampling-2The two major concerns of keeping the environment clean are water pollution and litter. These are harmful to humans, flora, and fauna. Clearing the litter can be expensive, and it can cause serious health hazards. One of the major concerns of litter includes cigarette butts. It is unpleasant to look at and forms a huge source of urban litter. These are difficult to break down, and these are the major source of litter. Keeping public places free from litter can promote a healthy living environment. Creating awareness on a litter free environment is essential. Unless people are aware, it is difficult to promote a clean environment.

Cleaning in big cities is conducted for extended hours. It can start at 8 am and go on until 2 pm. Modern cities need to have the street cleaned all the time. Street cleaning is a labor intense task and involves high cost. Though, street cleaning is only part of the way to keep the environment clean.

The role of the council health department is to provide people with pure water, air, food and protect them from diseases. In the modern days, street cleaning is promoted using modern equipment. These mechanized equipment make cleaning easy and effective. Water is an essential commodity for cleaning. Another major concern is river pollution. The poor depend on the river water for their domestic and drinking water needs. River pollution is inevitable especially with the sewage reaching the rivers. Discharged sewage has to be treated before it reaches the river downstream to prevent river pollution.

The water has to be tested for quality in the laboratory. There will be changes seen in the chemical and physical parameters. The color, taste, odor and turbidity of the water changes depending on the pollution level in the water.
