Development of Adhesive From Renewable Resources: A Green Revolution

Chemistry play important role in our life from last few decades and made the life comfortable through thousands of value added products. The petroleum is used as primary building block to developing these products. But the use of non-renewable petroleum is very energy sensitive, inefficient and toxic, resulting in significant energy use and generation of hazardous waste. Adhesives are also one class of end use products which are derived from non-renewable petroleum sources. The formaldehyde based adhesive primarily include urea formaldehyde and phenol formaldehyde adhesive which are mainly used for plywood, particle board, medium density fiber board and oriented standard board for construction. But these formaldehyde based adhesive has health related and pollution related concerns. The formaldehyde emission during the application of wood adhesive found to be carcinogenic according to world health organization (WHO)2-4. Also the prize fluctuations of petroleum sources are high due to limited reserve oil. So the immense pressure on researcher to develop techniques which would greatly reduce risk to fence line communities and safer products for manufacturers and consumers.
