INTRODUCTION
Due to Hong Kong mainly relies on landfill disposal and the existing landfill in Hong Kong will be saturated by 2020. Hong Kong now is facing a serious waste challenges, which 9,000 tonnes of municipal solid waste (MSW) were disposal in the landfill and food wastes are account for 3,600 tonnes every day. In this reflection notes, I’ll study few articles on the environmental issue that related to food waste management and possible environmental solution. Those articles general uses different case studies and data to proposed or introduce other countries actions on dealing with food waste problem, provide several means and solutions in order to tackle the food waste problem in Hong Kong. In more details, Cheung, J (2016) used the example of USA, how they used technology to commercialized food waste into fish feed

and Woon, K. both stated that technologies are needed to boost up the food waste-recycling rate in Hong Kong. After they have studies relevant case studies and technologies in several countries, they both proposed different solutions.
Based on the market demand, technologies availability, regulating obstacles, etc. Cheung, J. proposed to use black soldier fly bioconversion to turn food waste into fish feed, which fish feed is a common trade commodity and there has a huge market demand in Mainland China. Turning food waste into fish feed can tackle the food waste problem in Hong Kong and also can generate economic income by selling those fish feed to China.
On the other hand, Cheung, J. proposed to adopt a new technology to sort food waste from those MSW by optic bag system and recycling food waste into biogas fuel for vehicles usage. He stated that recycle food waste into biogas fuel is more workable due to it can optic bag system, providing lower emissions of greenhouse gases and doesn’t need to negotiate with the electricity providers in Hong Kong as turning food waste into electricity.
Food is the fuel for humans, supplying energy and nutrients to get them throughout the day. But how has the way of getting food changed as a result of industrialization? Consider the tomato; it is ripe, farm fresh, and transformable to any desired recipe. However, today’s tomatoes are grown in places that consumers would probably not be able to locate on a map, ripened with assistance of ethylene gas, and picked while they are green. The process of obtaining food has undoubtedly changed.
To begin, Royte’s writing includes clarity and quality to ease the reader into her plea. She includes quality research, such as expert testimony from Tristram Stuart, a pioneer in the global food wastage movement. Royte also includes a page of statistics that details produce waste to tracking the amount lost in production. Royte also shows her credibility by having background knowledge of the situation of food wastage. Royte is an accomplished environmental journalist that studies these very happenings.
The U.S. agricultural industry can now produce unlimited quantities of meat and grains at remarkably cheap prices. But it does so at a high cost to the environment, animals and humans”
Like global warming, pollution is universally known of, but many disregard it and its impact on their everyday lives. This image is successful in the sense that it reminds individuals of the problem of ocean pollution. By viewing the sushi made of trash, the thought of one consuming trash when eating seafood becomes a possibility. If a small fish eats bits of plastic, and a larger salmon eats many small fish and other polluted debri, that larger salmon could very easily be the same fish you had for dinner last night. In addition, the ad pictured above goes the extra step to include a jarring piece of research concerning the amount of plastic fish consume to justify its reasoning and prove the trash sushi a possible
We live in a world where marine life eat our trash, while at the same time, people go days without having something to eat. It is a sad but devastating reality. Everyday the world’s oceans continue to become a universal junkyard. Marine pollution continues to grow exponentially on the one resource that separates us from the rest of the universe. On land, there is a different problem.
Michael Pollan’s alternative to Factory farming has given a huge insight into a better ethics on food. In “The Animals: Practicing Complexity” Michael Pollan writes about a polyface farm and how it works. The goal of a polyface farm is to emotionally, economically, and environmentally enhance agriculture. Everything on a polyface farm has the potential to be helpful to something else on the farm. Pollan states “The chicken feed not only feeds the broilers but, transformed into chicken crap, feeds the grass that feeds the cows that, as I was about to see, feeds the pigs and the laying hens” (Pollan 345).
In the US, 40% of food produced, or approximately 365 million pounds of food, is wasted each day. Food waste, however, is a problem that extends beyond America, affecting billions of people as a global issue. The overwhelming amounts of food that are being discarded contribute to global warming and climate change, and prevent the massive number of hungry people from being able to eat nourishing meals. Humanity as a whole must be more mindful of the Earth and its health, as we are the source which most directly affect it. Due to the profound environmental impacts of food waste, a reduction in the amount disposed is necessary to create a more sustainable environment, and humans have a responsibility to protect the planet, even if it requires drastic changes to the current food system.
$ 31 billion worth of food is trashed every year in Canada. We on average throw out 1 in 5 bags of groceries. Many commercial companies and our government are ignoring this problem while the rest of the world has started to take action. Behind a Walmart store there is roughly 12 bins of consumable food thrown out. Not into the compost but into the garbage.
Meanwhile, the methods of waste disposal have improved over time. Also, that getting rid of garbage is quickly becoming a big problem due to our methods of waste disposal are only a temporary solution. Moreover; the waste that can’t decompose
“Food waste is an atrocity that is reducible, if not completely avoidable.” -Stephen Hough a famous composer once said. Food is a precious item many people do not have access to. Yes, you may have a surplus amount of food, but one should think about how much of that food do you waste. That food could go to the poor, unassuming and haggard people in society.
On the other hand, certain animals can produce “low-cost, high quality food for humans” (Tripp 24). A fact such as that can help impoverished countries that lack a steady source to provide nourishment. Without the improvement
Around the world, about one-third of the food that we produce is wasted and the food wasted can feed more than 1.6 billion people (Royte, 2016). Food waste is an economic issue. In developed countries, consumers make a great contribution to food waste. In the United States, about 40% of the food is wasted and a four-person family loses $4 per day on waste food and the amount is about $1500 per year (Save the Food). If people can stop wasting money, they can use the money to improve their life in other aspects, such as entertainment, education, and health.
Chapter 2 Literature Review 2.1 Waste management in developing countries: The Integrated Sustainable Solid Waste Management (ISWM) Cities and towns in developing countries have for several decades been faced with a challenge of handling and managing solid waste adequately. The main reasons associated with these challenges have been mentioned as rapid urbanisation and growing populations in towns and cities which consequently led to increased generation of waste (Guerrero et al, 2013). The management of this solid waste by municipalities grew as a budget burden for each municipality due to the associated high management costs, lack of understanding of the diverse factors that affect waste management at different stages and the linkages that
Introduction People tend to consume a lot, when there is consumption, there is waste – and that waste becomes a big problem that needs taken care of, which costs a lot of time, space and resources. If not managed, in turn, the world that we live in will become a hazardous place for all living things. According to the World Bank, people throughout the world, “spend $2.3 trillion a year on food and beverages alone” (Global Consumption Database, 2018), that is quite a lot. In addition to that, the world count mentions that, “we throw out over 50 tons of household waste every second. A number that will double by 2030”
ADVANTAGES OF GM FOODS World population is increasing day by day which implies scarcity of food will be the major challenge that the world will be facing in the future. Genetically modified foods can meet this rising need. 1)STRONG GROWTH: GMO is typically designed to have a faster growth. It can be grown in any harsh environment; each seed is improved to be stronger and can withstand herbicides and pesticides.
