Pulping

Mechanical pulping is typically used for softwood.One of the advantages of mechanical pulping is it has a great yield around 95% from dry weight of input material,however it requires great energy, because the resulted paper are opaque, weaker and easily to discoloration with the exposure to the light.The mechanical pulps are more weaker than the chemical pulps, however it ia more cheaper to produce (about 50% of the costs of chemical pulp). Moreover, they gives the yield with the ranging of 85–95%24

A stamping press is a machine press used to shape or cut metal by deforming it with a stamping die. The presses in Halewood produce body parts by processing two materials, steel (approximately 80% of the total parts) and aluminum (approximately 20% of the total parts). Figure ? depicts the key processes of the stamping operations at Halewood. Essentially, during the stamping operations, raw materials are transformed into vehicle body parts and to that end, each step in the process adds value to the

Dioxide gas as a pollutant is from paper production. The paper mills that produce pulp wood through a chemical process, normally combust their spent pulping liquor in a combustion unit. The most widely used chemical processes are Kraft Pulping process, Sulphite Pulping and Neutral Sulphite Semi-Chemical Pulping (NSSC Pulping). Among these, Kraft Pulping process is the most widely used process as it can be used to make strong and durable paper products. This process consists of digestion of wood, or

The Making of Paper Paper is a material manufactured in thin sheets from the pulp of wood or other fibrous substances used for writing, drawing, printing, or as wrapping material. Paper, whether produced in the modern factory or through the most delicate hand methods, is made up of connected fibers. The fibers can come from a number of sources including cloth rags, cellulose fibers from plants, and, most trees. The use of cloth in the process produces a high-quality paper. A large proportion of

Total Environmental Assessment for Pulp and Paper Industry in the Philippines Emil Adrian V. Fernandez M.S. Industrial Engineering Student Industrial Engineering Department, De La Salle University – Manila fernandeze@dlsu.edu.ph ABSTRACT Among current environmental issues, pollution is of major importance in terms of the impact on people’s health and their living and working conditions regardless of the origin or source of pollutants. The indiscriminate discharge of untreated wastewater, improper

Enzymes in Industry Enzymes are described as chemical a catalyst that is they speed up the rate of reaction. Enzymes have enormous potential in the commercial world. They are cheap to use in industry and they do not need high temperatures to work. They work at neutral PH and normal atmospheric pressure. This reduces the costs of fuel in industry and are energy saving. Also, enzymes can be reused. This means that they are needed in relatively small amounts in comparison

In brewing industry, 80% of overall final energy consumption is used in the form of thermal energy where solar thermal can be used for brewing processes as below: steam generation, malting process, stopping germination of grains, air cooling, conservation with hot air, power supplying of washing machines, wither and kiln processes. Malting plants and breweries consume heat for their thermally driven processes at temperature level ranges between 25°C to 120°C. It seems feasible to supply heat at this

The Industrial Application of Enzymes Enzymes are naturally occurring biological molecules found in all living organisms, plant, animal and microorganisms such as bacteria. All enzymes are proteins and, as with all proteins, are made up of a chain or polymer of amino acids held together by peptide bonds. This chain coils to form a specific three-dimensional globular shape, which, typically, means an enzyme will only work with one specific substrate. The purpose of an

This chapter contains literature and studies regarding the effectiveness of a non-wood plant as an alternative main material for paper production. While the first use of paper started as early as trace back to the beginning of the first millennium, paper still plays a significant role in modern everyday lives (American Forest and Paper Association, 2013). By far, paper industry is the largest consumer of natural fibers (El Omari, Zyane, Belfkira, Taourirte, & Brouillette, 2016). However, shortage
