On account of the investigated in blog C, the alternative system of organic waste I will focus on the university, the university students can understand the ability to accept new knowledge, and can accept in the short time.

Why does the composting is quite important?

When food residue is sent to landfill, they decompose to produce methane, then, the greenhouse gases more than 20 times, that the global warming carbon dioxide. Food waste landfill field is a potential source of decomposition and organic leachate pollution of surface water and groundwater. If food waste recycling, which contains the value of organic matter and nutrients can recapture.

Compost method is simple and organic material is decomposed into a large container or heap. Decomposition occurs because naturally occurring microorganisms, such as bacteria and fungi action. Small invertebrates such as earthworms and millipede insect, help to complete the process. The composting of organic wastes and turn into a rich, dark, or humus, in a few weeks or months. Composting process there is nothing mysterious or complex. Natural compost or decomposition occurs in the natural world all the time. Organic matter, animal and plant bodies, destruction and consumption of microorganisms and invertebrates to eat. However, under controlled conditions, the process can be speeded up.

Thus my alternative system is aim to reduce the waste landfill, to avoid or reduce waste generation, through recycling and waste management in the university.

Step 1.

Garbage classification based on different color and size garbage bins in university.

The first type is recycling garbage bin that can included the:

All types of cleaning paper and paperboard
Empty glass bottles and jars
Empty milk and fruit juice containers
Empty plastic containers
Aluminum and steel tanks

Empty coffee cup and cup of juice or smoothie.

The second type is landfill waste garbage bin. Such as chip package, packaging, food waste, plastic fork.

Although, the different garbage bin is not unusually, we even can see it on the street, thus, I consider in the university can have an organisation, that in order to allow you to help and achieve sustainable campus, this allow you to reduce the waste landfill and increase the amount of recycling. Moreover this organisation has many staff members are actively involved in some of organic wast on campus.

The staff also need to publicity the bokashi bucket composting system.

The bokashi bucket composting system is an alternative for transforming the kitchen waste into nutrient rich soil conditioner alternative. This composting system using Effective Micro-Organism, bokashi create ideal conditions for closed compost.
You can compost almost every kitchen food waste include fruits and vegetables in bokashi bin, prepared food, raw and cooked meat, fish, cheese, eggs, bread, coffee, tea bags, withered flowers and tissues.

We all know compost is good for our garden, but also has a lot of environmental benefits in the backyard. Thus, manage the organic waste is quite important. The environment impacts of organic waste are performance in the following respects:

1.Landfill Space

In many areas of land allocation to a waste disposal is rapidly filling. About a half of all household waste is organic. Most of the waste can be through compost utilization, turning waste materials into a used in the garden in the fertile soil.
By composting, not only can help reduce the amount of waste into the landfill can also help reduce pollution and greenhouse gases.

2. Benefit of composting

Nutrients in the compost are released into the soil as your plants need them.
Compost in clay improves drainage and helps to store water in sandy soils.
Compost assisted plant growth and disease resistance.
Compost also helps to absorb and filter runoff and protect the river from erosion and pollution.
Compost reduces unwanted insects, limiting the need for commercial herbicides and pesticides, thus preventing runoff pollution.
You don’t have to pack the garbage in the garden to collect the roadside or pay it to the tip.

3. Contamination

For garbage disposal of most of the land is not re-use, because of the pollution. This occurs in landfill is compressed and air is extruded. Decomposing waste anaerobic (without oxygen), which means that acid production. These acids can affect other trash items, such as plastics, resulting in a called landfill leachate toxic mixture. Collected at the bottom of landfill leachate and groundwater infiltration and from there into waterways.

4. Greenhouse gases

Organic waste is produced in landfills, which produce greenhouse gases, methane and carbon dioxide, which contribute to global climate change.
Most of the garbage landfill gas by 54% methane and 40% of the carbon dioxide. Methane than carbon dioxide greenhouse gas emissions 204 times. Scientists predict, climate change will affect our lives, especially in agriculture and human (health. viewed on 14, June, 2016

As a sustainable resource recycling leader, SUEZ believes that the future of waste management is based on a greater degree of resource recovery and recycling of organic materials in composting production. SUEZ’s organic recycling services help Australian companies to reduce their carbon footprint, while reducing the number of waste to landfill.


Management the organic waste has lots of benefits of the environment, thus, not only the government do this job, there have others organisation do this job as well, for example the MONASH UNIVERSITY.

In 2015, facilities and services to buy commercial organic decomposition weborganic recovery unit help further reduce the amount of garbage landfill will Monash University. The unit can reduce organic food waste from our food stores by impregnation, produced by dehydration of quality.

From Clayton campus of several food suppliers has been committed to provide equipment and services, provide food waste for the machine, the initial results to reduce the average weight of 70%. More than 4 months of time, the unit misappropriated nearly nine tons of organic waste landfill field. In the first 24 hours, the original material is reduced by up to 90% of the and transformed from compost. The unit production of dry film, then the Monash ground staff for landscape conservation soil conditioner.

In the hospital many of items are recycling and compost, the paper and cardboard are easy to recycle, and also can make a new sheets.  Moreover, this process can save the energy and reduce the reaching landfill. Organic manure can production by aerobic decomposition same as anaerobic decomposition. The most practical method is decomposition by the involvement of the earth worm.

How to choose the most appropriate research method?

Choosing the right type from different research methods can be a small and arduous one, at first. There are many factors to consider and evaluate. Research questions, ethics, budgeting, and time are the main considerations in any design. This need to look at the statistics, and study the preferred methods of personal science subjects. Each experimental design must make compromises and generalizations, so the researchers must try to minimize these, while the rest of the reality.

The research method has several types, such as: Experiments, Surveys, Questionnaires, Interviews, Case studies, Participant and non-participant observation, Observational trials, and Studies using the Delphi method. As the designer I always use the experiments, questionnaires, interview, and the observation.

The research about the organic waste, I focus on the questionnaires, surveys and the observation research methods.

My investigated is Sydney.

This interim waste strategy explains how the city of Sydney can meet 2014 goals in a more sustainable way to deal with garbage and focus on building and implementing is a long-term goal of reducing greenhouse gas emissions. The city of Sydney is expected to meet 2014 the NSW government to avoid the waste and resource recycling targets 66 yuan living garbage points shift away from landfill. The latest figures from our waste disposal contractor, city resource recycling recovery rate has reached this level. The city is likely to more than 2014 goal:

1.Encourage and support the recovery and utilization of domestic
2.Organic waste collection Garden
3.Treatment of garbage and advanced waste treatment to produce compost, no domestic waste directly to landfill
4.The use of procedures to deal with specific items such as garbage, household hazardous materials, household appliances and household cleaning up garbage.

The city’s challenges to provide more sustainable solutions, including the impact of the city’s people to produce less waste, to solve the problem of high density urban environment, to promote
The development of automated waste collection and advanced waste disposal systems, and to encourage the city’s business sector to become involved in these systems.

The city’s residents produced nearly 60000 tons of waste and recycling of 20102011 in this, about 29000 tons was excluded from the landfill, mainly through domestic recycling. In April 2011, an increase in the proportion of urban living garbage, sent to advanced waste treatment facilities, the production of compost. It is expected that this will lead to 68 of the garbage is excluded from the landfill. The questionnaires are detailed.

Except the domestic garbage, the commercial waste also influenced the Sydney’s environment. We can see the questionnaires of the fan statistical figure.

For solve the organic waster Sydney government has a design initiative of manage the organic waste. The automated waste collection master plan. City garbage is collected by a horse and carriage. The higher efficiency of the modern fleet of trucks, the method is the same; a container is placed on the side of the road, and a city workers to take it. The city is considering a new collection system, including:

1. Vacuum or automatic waste collection.
2. A collection of high capacity silos on the ground.
3. The public safety ground is collected in the ground, the improved functional rubbish bin.

Advanced waste treatment can reduce Sydney’s overall greenhouse gas emissions, and contribute to the city’s 70 greenhouse gas emission reduction targets of 2030.

POST A: Daily Waste

Conduct one day waste audit of all the waste I produced, I focus on two place, one is home, another one is the place that I worked.

My home has 4 people, and we get two garbage bin, one is daily life garbage bin, another one is recycle garbage bin. In my daily life, I did not have the garbage classification, although, my home owner did it. Thus, in my garbage bin at home, they are almost the fruit skin, the leftover food like rice or the noodle, carbonated drinks cans, or the snacks bag of one day. For the recycle garbage bin it can not fill in one day, thus I found in that bin it has the express delivery packing boxes, some plastic bags, the milk bottle, and water bottles.

For the one day waste of the place where I work, I found there has the coffee cup, the fruit skin, the water bottles, and the plastic bag.

Before this research I never attention I can produced a lot of food waste of one day, thus, I did some research about what kind of waste can be recycle. Summary the research data, the aluminum, steel, plastic and glass containers can recycling. Once you’ve collected the recycling collection, after the separation in a different location. Potential uses different such as plastic is used to do the winter wool and aluminum is used to set up a bike or a ship.

Overall, in one daily day, I can produced plenty of food waste, how about the restaurant? Thus I decided to go one Chinese restaurant near my please, and ask them about the food waste. The manager told me, because of the lots of storage food, that half of the food is wasted include the leftover food by customers, and the leftover ingredients in one day. Moreover I ask  about how to disposal the garbage, the manager said, thy are not go to the recycle garbage bin, and do the compost, the official stuff come to pick up the garbage and then the all garbage go to the landfill. We both know this way is not good for the environment, but we do not have the consciousness about waste disposal.

Analysis the food waste, there has a half are the organic waste, thus, I did some research about the organic waste on EPA. About 50% of household waste and 30% of the waste, we throw away is organic. It is a waste of resources, to fill the limited landfill space. Landfill decomposition of organic matter and the release of methane, a potent greenhouse gas and helps to Landfill Leachate Polluted River. The use of compost in horticulture, landscaping, horticulture and agriculture can reduce the need for irrigation, reduce the need for fertilizers, and improve the health and structure of the soil. Composting of organic materials in domestic large facilities is an increasing trend in New South Wales in order to better manage and utilize the waste organic material section.

Through my one day waste, I think the banana pills can be the organic wasted collected. Summary the research, the way from banana grows up to the end is:1. Grow within 30 degree of the equator 2. Travel long distances in refrigerated vehicles. 3. Ripening rooms where they are exposed to ethylene gas. 4. Shipped to grocery stores. 5. Finally to our homes. 6. 25% are throw away and end up in landfills.

In fact, the banana pills are benefit to the environment, the data analysis, the banana pills can:

1. fertilize tomato plants 2. feed indoor plants 3. use in compost 4. relieve rashes and itches 5. feed animals 6. make vinegar 7. tenderise meat 8. eat the peel 9. attract and butterflies and birds 10. polish leather and sliver.
