- Biotechnology
- The paper and board industry is placing greater demands on existing plantations and forests producing wood pulp because of the rapid growth in paper products.
- Only 10% of land in the UK is forested; as a consequence, timber products, including wood pulp and paper goods, represent the UK's fourth-biggest import.
- Biotechnology is the forefront of research, experimentation into genetically modified trees are the result of gene manipulation.
- This involves artificially inserting a gene from one plant into another, producing a change in the tree's biological characteristics.
- The main advantages to the paper and board industry from GM trees are:
- Quicker-growing trees to provide a sustainable supply of wood pulp.
- Resistance to disease and insect attack to provide high-quality products.
- Reduced strength of lignin fibres enabling a reduction in the amount of chemicals needed in the paper-making process.
- Biodegradable polymers
- These are materials derived from renewable raw materials that will decompose in the natural environment.
- Biodegration of polymers is achieved by enabling micro-organisms in the environment to break down the molecular structure of the polymer to produce an inert material that is less harmful to the environment.
- BIOPOL- it is produced naturally by renewable agricultural resources and, it is fully biodegradable.
