Keora (Sonnertia appetula) is the main species in the coastal region of Bangladesh. At present this species has no industrial or other application. In this paper, keora has been characterized and evaluated as a pulping raw material.

Jute mainly grows in eastern India. It has been used as packaging material for different commodities and also to some extent for carpet backing, hessian, decorative fabrics etc. Due to stiff competition from synthetic fibre, it is necessary to find some new uses of jute fibre and its by product.

Date-palm leaf (sustainable agri-residue) is an excellent raw material for making pulp and paper of various grades due to the presence of high alpha cellulose (50-55%), hemi cellulose (26-30%) and ultimate fibre-length (1.25 to 2.50 mm).

To meet the present day market demand in quality product, there was a high stress on pulp mills to develop highest quality of pulp with low operating cost in production to maintain profitability apart from meeting the norms stipulated by CREP, Central and State Pollution Control boards. Keeping this in view, improved washing and bleaching methodologies were followed.

Most of the Indian pulp and paper industry bleaches the pulp by conventional bleaching sequence (CEHH). The final discharge of the mill contributes to high COD load and AOX which is highly toxic in nature.

Recycled paper has come of age and continues to improve. But the next time you place an order for new stationary paper stack, be sure you are well-informed about what recycled paper actually is.

Pulp and paper mill requires a huge quantity of water and accordingly a substantial amount of spent liquor is generated. In this study purification of lignosulphonates (LS) present in spent sulphite liquor, a pulp and paper mill effluent was studied using continuous diafiltration.
