Advantages
Firstly, we should establish what home waste can be. Kitchen waste refers to the organic waste produced by food and beverages, including dishes, leftovers, edible food although expired, etc . This home waste taking scheme is principally aim to decrease the amount of waste and reduce processing costs.
Also, this plan of action could help to increase the life-span of landfills. This is a big challenge our company is facing nowadays as three landfills will be saturated inside the very soon long term.
Therefore , minimizing the amount of waste is the most important area of the scheme. Currently, among being unfaithful, 000 a great deal of municipal sturdy waste, one-third of the squander are made up kitchen spend, that means about 3000 plenty (Referring towards the diagram within the next page).
Besides, the kitchen spend could offer green organic and natural fertilizers after a series of processing. People might want to use these fertilizers rather than the chemical insect sprays. The organic and natural one is much more environmentally-friendly when you compare with the chemical substance one.
1991年至2010年於堆填區棄置的固體廢物數量
About one-third of the waste materials are made up kitchen waste, even though the volume of waste is minimizing year by simply year.
Backdrop
At present, more and more kitchen wastes will be produced from the canteen. We could observe that, everyday there are many learners cannot complete their meals. The incomplete meals will throw in the rubbish rubbish bin directly to become a part of spend. Undoubtedly, this sort of kitchen waste materials would be a responsibility of the canteen. It is because the canteen has to spend a lot of resources to manage the wastes. Moreover, the canteen frequently could not sell all their snack foods which are also another resource. We all know the prepared foodstuff cannot shop for a too long period of time and then the food has to be sold upon that working day.
When the meals is unsalable, they would ultimately become area of the waste. If this kitchen waste recycling where possible scheme could be implemented, there is lots of rewards to the canteen. For example , the price tag on dealing with the waste may be cut off. In the event this kind of charge can be reduced, the canteen could therefore spend even more resources to further improve the quality of all their food. In the other words, all pupils would gain from this system as they could enjoy a top quality of meal. As a result, the canteen may also sell more companies there would be fewer kitchen waste formed which can be actually a virtuous group of friends. Data (Out of 118 interviewers)
A lot of the interviewers accept to legislate your the plan. Majority of the interviewers are able to participate in this kind of scheme. Literary works Review
From the news article, we can see that currently, the food waste materials has been improved about 90 percentage. The food waste in 2002 increased from 373 metric plenty to 701 metric lots in 2005. As a result, the usage volume of landfills increased plus the life of landfills reduced. Therefore , we should execute your kitchen waste recycling scheme so the amount of food spend in landfills can be decreased and to enhance the lifestyle of Hong Kong persons. As in the articles said, Hong Kong persons waste a huge amount of food yet there are no recycling channels, so to work on kitchen waste materials recycle structure is necessary.
Technique
Intended for the method of recycling home waste, we are able to consult the process used in Taiwan that making use of the kitchen waste recycling containers to collect the kitchen waste. After collected some waste, a car or truck for taking kitchen might collect those wastes and deliver to the recycling back yards. After recycling the kitchen waste materials, we should classify the types of the kitchen waste. You will discover two key types of kitchen spend. The initially type is referred to as ‘cooked waste’, also called as ‘compost kitchen waste’. Examples which include uncooked fruit and vegetables, fruits, leafages, plants, and so forth The additional type is the more common one, that is compost to nourish pigs. Good examples inculding prepared food waste materials, rice, noodles, expired meals such as biscuits, raw meats, fish, shrimps, etc .
(For domestic)
(For large-scale)
Effect
Then the series of digesting work will be needed to accomplish. First, pre- treatment was carried out. Supply separated food waste brought to the pilot plant is definitely firstly delivered to the enclosed area for manual sorting and money of excessive waste water. The food spend is then mixed with bulking brokers (e. g. saw dust particles, bark chips) to achieve optimum porosity and moisture articles for the subsequent composting process. Then comes the creating process. The mixed squander is then fed to the composting drum models. Decomposition of food waste by biological bacteria actions takes place inside the drum. Temperature is released during the decomposition process. Temperatures inside the drum is stored between 55℃ and 70℃ for pathogens killing and optimum decomposition. Curing was then carried out. After residing inside the composting drum to get 10 days, the waste material turns into premature m�lange and is dismissed. The early compost can then be piled within the curing pads to undergo a curing period of regarding 30 days to make certain complete decomposition.
During the treating period, tilling and normal water spraying around the compost pile are performed regularly to keep optimum state for decomposition. After all this, final goods are made. The adult composts happen to be sieved with a vibrating merchandise screen to get rid of bulking real estate agents and pollutants before they can be packed for delivery to the users. Bark chips screened out from the older compost is usually reused inside the composting process as fiber bulking agents.
Debate
Benefits of carrying out the kitchen waste recycling scheme: 1 . It prevents the wastes at home decomposed and increase the hygiene of environment 2 . Reduce the amount of the waste products; reduce the large amount of waste control and also lowering the terrain fill and incineration flower 3. Decrease the levy of waste fees and waste disposal fees
4. The kitchen waste materials can convert into organic and natural fertilizer to enhance soil properties and green earth. 5. Can develop great habits of the people to enjoy resources and create resources sustainable progress society. Disadvantages of performing the kitchen waste recycling scheme: 1 . Require money and time to organize the process
installment payments on your Students have zero experience to end the process
3. This is difficult to collect a large amount of kitchen wastes.
Following comparing both sides of the factors, the advantages outweigh the disadvantages.
Conclusion
We think that canteen should certainly implement the scheme since we notice that many citizens waste materials large amount of foodstuff nowadays. To ease this situation, we have to train in the adolescents. Furthermore, the training must be started at the earliest opportunity. It is because many of us know that, practices are produced simply nevertheless really difficult to abstain. Besides, canteen can also improve their image by undertaking the system which is also one of the benefits they could gain. If the canteen has a better image to the school, the canteen might have a high probability to renewal. If we considering in the financial perspective, the canteen may also gain more customers, that is the students which may also take benefits for the canteen.
Representation
I think, this proposal is great certainly. It is because the kitchen waste recycling scheme can lead to a lot of benefits to different stakeholders and in distinct perspectives. For example , the canteen could benefit from gain even more customers; the students could have an improved quality of food; the burden of the landfills could be lowered; a greener lifestyle is promoted, etc . Therefore I desire more persons could stick to the habit, that may be to recycling the kitchen squander, or simply reduce the food squander to protect the planet. After polishing off this task, I was alerted by the data about the kitchen waste materials. From mention of the the data, we know that there are many kitchen wastes happen to be wasted in fact it is a serious problem. Since that, landfills and so are up very soon. In this proposal, we know that how you can resolve the difficulties and try our best to do better in our lifestyle. I will also encourage other folks people to accomplish that and I wish it can help to lessen the burden of the landfills.
Total, I think this can be a good scheme and I wish I can do better in other plans. During undertaking the pitch, I have a profound experience regarding the lifestyle of Hong Kong people. From the data on the volume of squander, I have discovered the amount of kitchen waste increasing annually with large amount. Therefore , to hold the life of landfills for a longer time, we need to take education to the people so that people can have mind to modify their way of life. If canteen carried out the scheme, it can give a assist to bring up habit which is will not wasting food. I used to leave some food after i went to have got lunch. I did many researches on how kitchen wastes had been recycled and just how useful are the kitchen waste materials. I think recycling where possible the kitchen wastes is needed in Hong Kong. Seeing that a lot of people can’t say for sure what to do with home wastes, they just throw them in the rubbish bin. If there is a kitchen waste materials recycling system, citizens of Hong Kong will probably be willing to interact personally.
I will not really waste foodstuff anymore if there is a home waste recycling scheme. Once we think about how you can save the planet earth, we constantly consider the reuse, reuse, reduce and replace. But we aren’t always view the kitchen wastes recycle in Hong Kong. The proposal gives us the chance to consider that how to apply the recycling where possible of kitchen wastes in our daily life. We experienced some difficulties when we considered as the content. For example , we must pick the method of procedure the kitchen wastes. Different ways of processing the kitchen wastes uses into distinct place. Some can be refined into the meals of the pig; some can be processed in to the fertilizer. For example , we need to acquire the kitchen wastes from the college canteen. Then, we can procedure the wastes into the fertilizer but not the foodstuff for this halloween. We must pick the sufficient strategy to recycle your kitchen wastes cautiously. This is a good chance for us to know the method of recycling your kitchen wastes.
