Bleaching of wood pulp

Industrial Hemp is an ancient crop, which has a multitude of diverse uses. The earliest uses of Hemp can be traced back to the Sumerians and probably even earlier in man’s unrecorded history. Industrial Hemp is not Marijuana though the two plants are of the same family and have passing resemblance to one another. Industrial Hemp’s myriad uses are being rediscovered and at the forefront of research in diverse fields. I will be attempting to dispel some of the myth, and providing history and proven

Impacts of the Paper Industry, 2016). These chemicals are used “to prevent bacterial growth in the pulp and finished paper products” (Environmental Impacts of the Paper Industry, 2016). Poisons released into the air in Georgia from the paper industry “include nitrous oxide, carbon monoxide, sulfur dioxide, and volatile organic chemicals” as well as “mercury”, “cellulosic fibers”, and “chlorophenolic wood preservatives and anti-sap stains” (Jackson, Standiford, Smith, Spencer, & Tyler, 2014). Paper production

Literature review 2.1 Lipases Lipase is the enzyme that also known as triacylglycerol acylhydrolase with EC number 3.1.1.3. It is part of hydrolases family that act on carboxylic ester bond. It had been widely used as biocatalysts in biological process. Most of the lipase was expressed from natural resources such as plant, animal and microorganism. Lipases expressed from microorganism particularly interest due to easy production, capability to adapt in industrial application (Wang et al., 2017)

EEI Daniel Blinks YR. 11 Background – Catalase are an enzyme that catalyses the reduction of hydrogen peroxide into H2O and O2. Catalase are a common enzyme that can be found in almost all living organisms such as potatoes. It is specifically found in the cells that are exposed to oxygen and can be in a plant or animal cell. [1] The effect of heat above 400 on catalase will make them denature and the production of O2 will slowly decrease. However when the catalase are too cold the rate of O2

Hemp Some may read the title of this section and think to themselves "is he going to talk about a drug?" No, here is my disclaimer, hemp/industrial hemp as it is sometimes called, is cannabis, but is not marijuana. It does not contain any psychoactive properties so therefore it is not a "drug" which is a common misconception or lie people believe to be true. THC (Tetrahydrocannabinol) levels in hemp are too low to have any effect whatsoever and are in such low quantities that it cannot be detected

The Origins of Cannabis The oldest known written record on cannabis use comes from the Chinese Emperor Shen Nung in 2727 B.C. Ancient Greeks and Romans were also familiar with cannabis, while in the Middle East, use spread throughout the Islamic empire to North Africa. In 1545 cannabis spread to the western hemisphere where Spaniards imported it to Chile for its use as fiber. In North America cannabis, in the form of hemp, was grown on many plantations for use in rope, clothing and paper. It is important

 (Source: Marine Ecosystem: EMCBTAP-ENVIS N Marine Pollution: Causes and Consequences Pollution of the world's oceans is quickly becoming a major problem on Earth. We know very little about the effect that pollution has on the oceans, but we continue to dispose off chemicals, sewage and garbage into it at an unprecedented rate. Most people likely do not even know what types of pollutants reach the oceans. There may be billions of people unconcerned about ocean pollution and hence this

Making new products from non recycled materials causes natural resources to deplete. (Castro et al 2009). Most of the recyclable items we use everyday are made from plastic, paper, glass or aluminum. While manufacturing papers we use wood pulp from trees, producing plastic requires the use of oil as well as natural gas. We can say that making products from recycled materials means using fewer natural resources, that means less trees will be cut and not as much oil will be used

and acrylic. (Udale, 2008) Often referred to as artificial silk because of its silk-like aesthetic, rayon was one of the first man-made fabrics to be developed having been in production since 1885 (Udale, 2008). Constructed from the cellulose of wood pulp, it was made to “simulate natural fibres as well as to provide characteristics of its own” (Corbman, 1983: p.9). Like cotton, it is soft, comfortable and versatile; it blends well with other fibres, and is often used for evening gowns as an alternative
