Pulp and paper

Eucalyptus is one of the important plant species for paper pulp, fuel wood, and timber. In this study, a hybrid Eucalyptus, U16 line, was investigated for rapid in vitro propagation. The apical and adventitious shoots served as initial explants. These were free-disease symptoms that were collected for surface sterilization.

In addition to its effects on air quality, stubble burning also affects soil fertility (through the destruction of its nutrients), economic development and climate. The crop stubbles (if managed properly) could provide immense economic benefits to the farmers and protect the environment from the severe pollution. Some of the alternative management practices include the incorporation of the stubble into the soil, use of stubble as fuel in power plants, use as raw material for pulp and paper industries, or as biomass for biofuel production.

Pectinases find wide application in different industrial applications, e.g., textile, food, tea, paper and pulp, vegetable oil extractions, saccharification of agricultural remains, and in fermented drinks. Three fungal strains were screened for pectinase production. Results indicated that all strains are capable of producing a pectinase enzyme.

In the present study, A.flavus and A.fumigatus isolated from pulp and paper mill sludge showed tolerance and accumulation of toxic metals from synthetic medium and paper mill effluent. Effect of heavy metal ions on fungal growth in terms of their biomass (dry weight) was determined and conformed energetic fungal growth after increasing the concentration of Pb2+ and Zn2+ point out the importance of these two fungi for bioremediation.

The conversion of waste lignin from the paper and pulp industry is a potential process to produce chemicals and materials in the industry. With the development and the demand for the pulp and paper industry, the amount of waste lignin will increase remarkably. In Vietnam, the forest tree for the pulp industry is abundant, and the pulp industry has increased in recent years. In parallel, the government planned to develop the material resource and high-tech factories for this industry.

Gum is natural biopolymers and formed via process of gummosis due to biotic and abiotic stresses i.e. injury, infection, drought, heat, high temperature, asby product of metabolic pathway and cannot re-enter in the system. Gum karaya (Sterculia urens Roxb.) is a dry deciduous tree belonging to the family Sterculiaceae distributed throughout India and Chhattisgarh. Karaya gum is the dried exudate obtained from trees of Sterculia species. Karaya gum is predominately used for many industries such as petroleum and gas, textiles, paper and pulp, pharmaceuticals, medicine and several other products.

Fruit leathers are made by drying a very thin layer of fruit puree to produce a product with a texture similar to soft leather. Fruit leather is the product prepared by blending fruit purees or pulp extracted from ripe pulpy fruit, sugar or other nutritive sweeteners and other ingredients and additives desired for product and dehydrated to form sheet which can be cut to desired shape and size. The preservation of fruit leathers depends on their low moisture content, the natural acidity of the fruit used and high sugar contents.

This study was carried out to determine the suitability of sago starch blended with acrylamide as paper additive. Solutions of unmodified and blended sago starch with acrylamide, were prepared at 5% weight over volume (w/v) basis before the basic properties (i.e., pH, viscosity and solid content) were determined. The starches were then used to coat on laboratory made handsheets from recycled pulps. Various effects were studied, namely, modification of sago starch, addition of different types of initiator and further curing at different temperatures.

Alkaline pulping liquors are the problematic for environment due to their toxicity and poor biodegradability. During last decade, anaerobic treatment technology has been successfully applied to various types of pulp and paper industry effluents. In the present study, the treatment of highly toxic pulping liquors in lab-scale has been done using sulfate reducing bacteria (SRB) isolated from sediment samples of pulp and paper mills in Vietnam. This treatment could reduce 70 - 75% of COD after three weeks. The COD removal could achieve 82 - 88% by subsequent aerobic treatment in 48 hours.
