Explanation:

The city of Yamunanagar derives its name from the Yamuna that flows on the north-eastern side of the district. In the pre-Partition days, timber logs from Shivalik hills of Himachal Pradesh (then part of Punjab) used to be transported through the river for marketing. This facilitated the evolution of the timber market in this city. Over the years, this city has become a hub of wood-based industries producing more than 50 per cent of the plywood of the country. Hence, it is called the “plywood capital of India”. This hub has not only halted the spread of Chinese plywood in the country but is also exporting wood products to other countries.

Yamunanagar city is famous for old industrial culture—Ballarpur Paper and Straw Board Mills Ltd. was established here way back in 1928. This unit had initially used forest grasses, inferior woods and agro-wastes as raw materials but later shifted to pulp wood of eucalyptus during 1970s.
