The need for enzymes
Several types of enzymes are used in the packaging and board segment to achieve specific objectives. Typically, these include refining energy reduction, fibre modification, fines management and viscosity modification of starches.
Depending on the raw materials and finished products, requirements differ from time to time in specific mills and vary considerably across mills. Careful selection of the appropriate type of enzyme is of key importance as enzymes are used to achieve specific objectives and in different areas of the board making process.
- Requirements for long fibressuch as softwood is managed with cellulase enzymes, which increase the fibrillation to improve strength properties in addition to reduction of refining energy.
- Fiber modification and fibre development are important factors for shorter fibressuch as hardwood and mechanical pulp, where costs can be reduced through energy cost saving and improved productivity.
- Waste paper based mills have to deal with weaker fibres/excessive fines and enzymes can play a vital role in managing the productivity of the machines in addition to increasing the recycled content.
- Viscosity modification of starches by enzymes is an important application for size press starches.
Dosage levels, feed locations vary based on wet end configuration of mills and desired objectives. Dosage levels typically range from 50 g/ton to 500 g/ton of paper produced. Dosage in starch varies from 50-100 gm/t of starch used.
