Explanation:
Raw Materials
Materials required to produce a commodity are called raw materials. Factories require large and continous supply of raw materials. You will find dozens of lorries supplying raw materials to them everyday. Paper mills generally use wood from bamboo, eucalyptus and subabul trees. Subabul wood a large number of chemicals such as common salt, caustic soda and so on are also used in different stages of paper making. Scrap paper is also recycled in paper mills.
Factories use heavy machinery which are run by electricity. Paper mill needs electricity for operating its machines. The paper mill shown in the picture of example, requires nearly 25 Mega Watt every year. More than half of the electricity, the mill requires a large quantity of clean water throughout the year.
Paper mills and Disappearance of Bamboo
Although raw materials for paper are available in the forests, it is not very easily procured. Paper mills are generally established near forests where bamboo and other soft wood trees are available.
Paper mills engage contractors to supply bamboo and other raw materials. A few decades ago, contractors employed tribal people(like those living in Kunawaram hills you read about in class Vi) to cut bamboo from forests. Due to excessive cutting in the past, there are no bamboos available in forests near the paper mills now.
Hence, paper mills are looking for alternative raw materials like subabul which are grown in villages. This led the government to encourage people to grow subabul trees on farm land. Now-a-days, paper mills bring wood from distant places.
When we visited the paper mill, we found 4-5 lorries with loads of subabul wood waiting outside the mill gate. Only after 9.30 am, they would be allowed to enter the mill. There were separate gates – one for the workers and the other large gate for te vehicles. We had prior permission from the paper mill authorizes to visit the paper mill. We entered our names in the register at the security room near the gate and went into the mill. Later lorries also entered the mill.
