Carbon Footprint Essay

Biodiesel production is usually expressed through the process of trans-esterification reaction. Recently, homogeneous catalysts are broadly preferred for biodiesel production in eminent scale operation. Still, they are toxic, highly flammable and corrosive in nature [1]. Boey et al. analysed the purpose of the waste cockle shell from palm olein oil in biodiesel production of Anadara granosa. At 900 °C the waste shell was calcined for 2 h that mainly compiled of 71% of Ca to develop an active…

The Carbon Cycle Addition of carbon to the atmosphere Respiration: Through respiration, carbon dioxide can be added to the atmosphere. Living organisms use respiration to turn food into usable energy. Aerobic respiration requires oxygen to take place, and produces carbon dioxide, releasing it into the air and atmosphere. The energy taken from the food molecules following digestion is used to fuel the organism, additionally when mixed with oxygen, releases carbon dioxide when exhaling.…

What is a laccase? Laccases (EC 1.10.3.2, benzenediol: oxygen oxidoreductase) are monomeric, dimeric or tetrameric glycoproteins that are typically extracellular and categorized as multi copper oxidases (Mate and Alcalde, 2016a).They catalyze the oxidation of compounds that are coupled with the four-electron reduction of "O" _"2" "to" "H" _"2" "O" . They are regarded as eco-friendly enzymes. Laccases have been first discovered in 1883, which makes it one of the oldest enzymes ever observed…

Zinc is the member of the first row transition series of elements, consisting of Sc, Ti, Cr, Mn, Co, Ni, Cu, Zn, Cd and Hg. All these elements belong to group 12 of periodic table. Zinc has an atomic number 30, an atomic mass of 65 and one main oxidation state (+2). Zinc has five nature isotopes . Zinc is the 24th most abundant element in the earth’s crust. Its properties is very similar to Cd.Zinc is very useful in biological systems. Zinc also is involved in many biochemical processes that…

Different technologies are available for the treatment of gaseous streams containing VOCs (Volatile Organic Compounds), namely catalytic or homogeneous combustion, absorption, adsorption, etc. The goal is either to recover the VOCs, or to destroy them, thus avoiding, in both cases, their emission into the atmosphere. The treatment of “lean” streams, where the concentration of the VOCs is particularly low (e.g. lower than 1% v/v), is a particularly challenging case study as the low concentration…

A benefit versus cost analysis of the United States Coast Guard Oil Prevention Spill program, concluded that efforts to reduce oil spills pays off. Resources allocated to safer working conditions and optimal maintenance suggest that reduced environmental damages could total 3.5 million dollars saved, 1.5 million saved in cleanup costs and approximately 1 million dollars of oil saved. Various ways to prevent oil spillage are the assessment of the technology used in transport and drilling,…

alkane which has been replaced by an –OH group (Chem Guide, 2003).The general chemical formula for alcohols is CnH2n+1OH (BBC, 2014).Alcohols are any of a class of organic compounds characterized by one or more hydroxyl (−OH) groups attached to a carbon atom of an…

Assignment 7 Power Station Emission Aim: The aim of this experiment is to measure the mass of sulphur dioxide in 1m3 of flue gas (waste gas from burning fossil fuels in a power station). To achieve this aim, titration of an unknown solution of sulphuric acid (around 0.2-0.4 mol) and sodium carbonate (0.2 mol) using methyl orange as an indicator. 1. Introduction Fossil fuel is formed from decayed plants and animals that have been converted to crude…

water’s cycle, the Carbon cycle was more about chemical elements in the ecosystem-atmosphere. Before diving into the subject, to refresh my memory I went back to read book and article to have a good understanding of this cycle. As asserted by Holli Riebeek, carbon is the backbone of life on Earth and mostly all terrestrial beings are made of carbon. Also, carbon was also the fourth largest element in the universe, forged in the heart of dying stars. An article explaining the origin Carbon by…

can join who's main goal is to protect coral. Protest against threats like over-fishing, pollution, or waste being dumped into the oceans. Simply living a more sustainable life can make a difference; conserve energy and pay attention to your carbon footprint. Following the reduce, reuse, recycle rule can make a more significant difference than you would…
