The wood of a mature (40-year-old) Eucalyptus globulus Labill tree was characterized at different stem height levels (0%, 10%, 35%, and 50% of total height) regarding pulping, bleaching, and paper properties. Pulp yields increased upwards from 46% to 50%, and Kappa number decreased from 17.5 to 12.3 at 0 and 50% height, respectively. The estimated specific wood consumption ranged from 3.2 m odt...

The pulp and paper industry has started applying new, ecologically sound technology (biotechnology) in its manufacturing processes. Many interesting enzymatic applications have been proposed. Implemented technologies tend to change the existing industrial process as little as possible. Enzymes have great potentials in solving many problems associated with the use of recycled fiber, especially r...

This study aimed to identify suitable sites for tea cultivation using both random forest and logistic regression models. The utilized 2770 sample points map the plantation suitability zones (TPSZs), considering 12 important conditioning factors, such as temperature, rainfall, elevation, slope, soil depth, drainability, electrical conductivity, base saturation, texture, pH, normalized difference...

The current state of salinity irrigated soils in the area Sarpinskaya hollow Caspian lowland has been studied, using example Duboovrazhny plot Volgograd region. At peak irrigation 85-90s last century, forage grasses were cultivated on plot, was carried out by sprinkler irrigation, groundwater level remained satisfactory, and there no foci secondary soil salinization. Currently, is a private far...

Nilgiri tea is a vital perennial beverage variety and in high demand global markets due to its quality medicinal value. In recent years, the cultivation of plantations has decreased extreme climate prolonged practice same area, decreasing taste quality. this scenario, land suitability analysis best approach evaluate bio-physiochemical ecological parameters plantations. The present study aims id...

The importance of recycling and utilization of recycled fiber has recently been recognized because of concerns about environmental issues and economic aspects. In spite of several advantages offered by paper recycling such as wood savings through substitution of virgin pulp and reduction in chemical usage, recycled pulp also contains plenty of fines having high relative surface area and hig...
