HELLOOOOOOO EVERYONE

INTRODUCTION: This proposal has been developed to implement best practice on the reduce food waste by converting it into a source of renewable energy and liquid fertilizers via anaerobic digestion process at SIT @Punggol. Singapore has gained its reputation globally as a “clean and green” country over the years by implementing innovative and sustainable solutions to current environmental problems. However, methods for food waste management can still be further improved. According to the waste management and recycling statistics (NEA, 2017), the total food waste generated in Singapore is approximately 676,800 tonnes, but only a small percentage of 16% is being recycled. The amount of food waste generated is expected to increase in the future due to the growing population in Singapore.         Figure 1: Food waste generated over the past 10 years (Source: National Environment Agency 2018) There are other challenges towards food waste recycling such as odour and

In this article "4 Ways to Demolish a Building", Rodriguez (2018) discusses the four methods demolition experts use during demolition. The author begins with implosion, the detonation of explosives along the main structural components, causing a building to collapse onto itself. The second method is known as the high reach arm demolition, where a base machine attached with a demolition tool will tear down tall structures from the top down for a ground team that will clear the fallen debris. The author then moves on to its riskier counterpart, the wrecking ball method. Limited only by the surroundings and the size of the crane, a skilled crane operator can easily decimate the building by striking a 13,500-pound wrecking ball repeatedly, producing dust, vibration, and noise. The author then ends with selective demolition, where builders recycle materials from old buildings, reducing overall cost while having a downside of higher labour demands and its incompatibility for light
