Storage & preservation of raw material:
Suitability of various types of preservatives has been established to protect raw material from decay. |
Process for producing biokraft pulp from eucalyptus chips:
Bio kraft process reduces utilization of energy and cooking time, improves pulp strength (US Joint patent obtained by ACIRD and Biopulping International, Inc). |
- Surfactant and AQ in combination during pulping:
- Pulping additives reduces active alkali demand with improvement in pulp viscosity, reduction in refining energy requirement and improvement in pulp production.
|
- Fractionation of bamboo pulp:
- The developed and patented process produces long fraction pulp with superior physical properties which can substitute softwood fibre in ESKP manufacture.
|
- Process for the production of dissolving kraft pulp using xylanase enzyme:
- The developed process reduces bleaching chemical demand and improves pulp quality (Joint patent obtained by ACIRD and BGPPL).
|
- Enzymatic refining of pulp:
- The application of enzyme resulted in reducing the refining energy requirement, and improving the drainage of pulp.
|
- Peracetic acid in different stages of bleaching:
- The oxidative chemical improves pulp brightness and whiteness.
|
- Utilization of banana stem for papermaking:
- Banana stem pulp is a blend of both short and long fibre fractions. Long fibre fraction with propertes comparable to soft wood, was found suitable for making speciality paper like tea bag paper, Short fibre fraction was found suitable for making glassine, greaseproof and barrier papers. The plant scale trial with banana stem pulp demonstrated the substitution possibility of imported soft wood fibre in certain specialty grades of paper. Additional information is available at:

- Reactivity improvement of dissolving grade pulps by enzymes:
- First time we have been able to significantly improve the reactivity of dissolving grade pulp by application of enzymes.
