Blow Moulding is a manufacturing process used to produce hollow plastic parts by inflating a heated plastic tube until it takes the shape of a Mould cavity. This method is particularly effective for creating products with consistent wall thickness and complex shapes. Developed in the mid-20th century, blow Moulding has become an integral part of many industries, including automotive, packaging, and agriculture. In agriculture, the process has seen significant advancements and is used for making various products, such as containers for pesticides, irrigation equipment, and even large tanks. This blog will explore the blow Moulding technique, its current practices, applications in agriculture, and future perspectives. Blow Moulding Technique: Process and Variants The blow Moulding process involves several steps: 1. Parison Formation: A plastic tube, called a parison, is extruded. The parison is then pl...
Introduction
India’s objective is to become self-sufficient in energy and reducing its dependence in crude oil import form oil reach country. Bio ethanol is one option for becoming india self suffient in energy.
The country’s first biorefinery, Assam Bio Refinery, built by Chempolis technology, is a new joint venture that will be the only refinery in the world to create bioethanol from bamboo – available in abundance in north-eastern India.
Food crops like beet and sugarcane, rich in starch and carbohydrates, are currently the leading sources of ethanol. But ethanol, made from the cellulose of trees and grasses, could be even more promising. And bamboo, which isn’t generally a food crop, seems ideally suited for this purpose. Leveraging bamboo so that energy consumers and food consumers aren’t competing for the same crop is one advantage.
A fossil fuel, petroleum comes from fossils takes about a hundred million years to replace.
Bamboo takes only about five years to get established and reach maturity. From there, it can be grow continuously. And like the grass in your yard, it just keeps growing . As it grows, bamboo produces about 30-35% more oxygen than an equal area of trees.
There are two methods of production of ethanol
1. Conventional Method: In this method starch and sugar breaks down into ethanol in presence of yeast. Later water is distilled out leaving behind pure ethanol.
2. Cellulosic ethanol : This method requires tree and grass like bamboo to produce ethanol, there is one additional method of breaking down cellulose in sugar using cellulose enzyme. And separate sugar from lignin. Cellulosic structure makes more difficult for production of ethanol. But this has more advance over conventional method.
a. Using Grains like wheat and and corn puts added pressure on food supply.
b. Trees and grasses can grow in a wider range of climates and soils, making them a more practical alternative to grains.
Bamboo cultivation in India
Bamboo is most commercially cultivated crop in India. India is second largest county in world for production of bamboo after China. The Yearly production of bamboo in India is nearly 3.25 million Tons. The north-eastern states are the major bamboo producing states in the country.
It requires hot and warm climate to grow. Bamboos can be grown and cultivated on a wide variety of soils except for rock soils. Usually bamboo planting is done in the rainy season.
The unit cost for one acre of bamboo plantation is around Rs 9400 spread over a period of five years. Harvesting starts from the sixth year onwards. Appropriate pesticides should be applied to control pests.
