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.
