The Great Recycling Swindle 1. Introduction Recycling is a common practice around the world to reduce the overall quantity of resources needed to produce new products. Whether recycling is cost effective compared to the benefits is widely an unknown detail. The public while weighing the benefits almost never considers the cost of energy and labor in combination with undesired effects of pollution associated with recycling. 2. Recycling Saves Money Commonly people accept recycling saves money in

Summary Introduction Section 1: Maturity of Desalination Techniques(Ben) 1.1 National Use of Desalination 1.2 Desalination Methods and Maturity Australia, as the driest inhabited continent, had installed 331 desalination plants supplying high quality water to the increasing population. Another country, China, also implete the use of desalination plants to tackle the drought and large population problems. This section will compare several technologies used in these two countries. As shown in Table

“Dulce Et Decorum Est” is an anti-war poem, written by a soldier in the british army during World War 1, who ended up being one of the leading poets of the first world war. In his poem, “Dulce Et Decorum Est”, Wilfred Owen uses diction to evoke grotesque imagery that portrays the true horrors of the WWI battlefield in contrast to the blind patriotism promoted by propaganda. There is a great presence of juxtaposition used throughout the poem as a way to emphasise contrasts between war and propaganda

Investigating Ethical Qualms of the Modern Toilet Nina Levison Initial interest and topic expansion This paper started as a way to talk about my ethical qualms with the toilet and see if there was a scientific basis to back them up. More than a history or philosophy of how the modern toilet came to be, I wanted to see if there is scientific evidence to back up my idea of toilets and the modern sewage treatment systems as wasteful. In order to understand the wastefulness, or efficiency, of the toilet

Water is the necessity of life without it every living organism on the planet parishes. This of course does not stop human kind from exploiting and abusing this priceless resource. Considering the planet is predominately water it is surprising to know that only 2.5% of the planets water is actually drinkable (Withgott, 2014). Of that 2.5% there is 70% of it going for agriculture alone which means that there is less fresh water to go around just to sustain the growing population (Withgott, 2014)

sources, a source of fish, the easiest mode of transportation from village to village, and a major draw to tourism. As seen in the documentary Atitán In Bloom, pollution consisting of a green sludge is negatively affecting the lake, with villagers scooping this up and taking it away by the truckload. The sludge consists of recently bloomed algae and cyanobacteria, which is harmful to people. Trash and sewage as well are a large portion of the pollution. Without stopping, and hopefully reversing, the

SECTION THREE 3.1 HISTORICAL INCIDENTS AT RINGSEND WASTEWATER TREATMENT PALNT The odour complaints has been historical at Ringsend, dating back from the operations involved in loading the ship which carried sludge to be dumped in the Irish Sea. According to the report (Fehily, 2008), commission by the Minister for Environment, Heritage and Local Government in October 2008, due to the persistence odour complains from Ringsend WWTP, which resurfaced when the contract 2 was commissioned in May/June

2014); and • To determine the observed sludge yield (g VSS/ g COD) at the different HRAS operational conditions (SRT, DO, HRT). 3.1.3 Research Questions The focus on this research is to find the optimal conditions for the operation of a very efficient carbon removal process that be able to

potential of energy recovery from wastewater in form of biogas. The effluent can also serve industrial heating and cooling purposes. Wastewater has a huge potential of electricity generation. Technologies exist for on-site energy recovery through sludge/biosolids treatment processes integrated in wastewater treatment plants, allowing for transition from major energy consumers to energy producers. Strict standards for discharge often require energy intensive advanced treatment technologies. As a result

like food packaging items, or even hard-to-break-down foods, like bones, fruit pits, coffee grounds, or oil and grease. These items add up in septic tank, and as the sludge accumulates, it takes away from the full capacity of the tank. Ideally, the bacteria and treatments will help to break down the components that are causing the sludge, but as the larger, heavier pieces sink to the bottom more quickly, the bacteria doesn’t have the time to do its
