Restatement problem definition technique

Re renderment b separate definition techniqueTask 1The mathematical function of the task is to choose unitary of the scenarios and to apply the Present recite/craved e no.nce, Duncker Diagram and Statement/Re solid groundment problem definition technique. The scenario 1 is about the problem associated with the cycle of post-consumer botch up. It has been observed that even in the most cooperative and environs conscious communities, lay ins of utile hook contains 10% of ill-timed useful or non-reclaimable textile. For disposing non-recyclable square present in recyclable bins, recycling keep fellowship has to reach lot of specie. The problem needs investigation from the recycling company CEOs channelize of view.Summary of additional information ga theredGeneration of languish is strongly associated to population and urbanization 1. Improvement of existing waste management technique is a prime concern for developing countries. In past, the most twopenny-halfpen ny practice for disposing waste was to place it in landfills. Despite the fact that the landfills were apply to manage the waste, the need for restitution of the landfills, release of toxic gases, limited availableness of the land for the landfills and so forth, still remains a great challenges for metropolitan cities. The al musical modes increasing post-consumer waste has many adverse effects on the health of people, such as pollution of underground water and soil, bad timber from landfills and release of green ho part gases like CO2 and CH4 1. The concept of 3Rs which says reduce, employ and recycle has become a key notion for waste management. The finest agency to manage waste is not to create it. Generation of waste should be minimized at household level by avoiding excess use of non-environmental friendly goods. Recycling is the also one of the ruff option for waste management as it offers several advantages like utilization of waste which would other be dumped in landf ills and also decrease in use of peeled re character references 2. Novel methods of sorting non-recyclable waste from recyclable should be brought in use. The toil capacity of paper in Malaysia has reached up to 1,300,000 T/ yr 3 hardly it is still low as compared to the consumption of paper there. Paper mill in Malaysia are directly relying on machines which john sort diametrical grades of paper. After sorting, high quality paper can be recycled. Malaysian paper mills are saving lot of money, energy, reducing the step of landfills, reducing incineration and above all conserving their natural resources 3. Shutting down of Freshkills Landfills in Staten Island in 2001 has strained the city of New York to find other methods of waste management. To dispose huge amount of waste, New York City is exporting move of its waste to Virginia and its neighboring state. Remarkable increase in disposal tipping fees in recent years has forced New York City to find other methods for waste m anagement. Recycling provides a striking choice as it helps in decreasing pollution, providing employments and preserving energy. municipal Corporation in New York City is now relying on materials recovery facility (MRF). MRF collects waste, segregates wrong or non recyclable waste from recyclable waste, recycle the waste and stores it as raw material for manufacturing industry. By doing this, City of New York is saving nearly $46 million per year from the total amount it fleets today for waste disposal 4. Present state/Desired State TechniqueDiscussion The present state dialog about the presence of wrong or non-recyclable material whereas in demand(p) state talks about maximizing companys profit by proper insulation and disposal of non-recyclable waste. There is no match between the present state and the desired state. Further reworking of statements is required. Discussion These states are matched, but there is no clear difference between the present and the desired state. Des ired state somewhat solves the issue in present state i.e. company has to spend money for disposing non-recyclable waste. Actual problem is not resolved yet thusly further reworking of solution is required. Discussion There is perfect one to one mapping between present and desired state. The problem addressed in present state is completely resolved in desired state. The desired state focuses on attaining zero percent contamination in recyclable bins. Therefore, if there is no non-recyclable or wrong recyclable material in recyclable bin there is no point in disposing it and there is no price for disposing it. These statements can therefore be considered as the best statements for actual problem.Duncker DiagramStatement-Restatement Technique Original problem statement Bins of recyclable material contain 10% of wrong or non-recyclable material and recycling company has to spend money for its disposal. touch off 1 Emphasizing on different language and phrasesBins of recyclable materi al contain 10% of wrong or non-recyclable material and recycling company has to spend money for its disposal.Is there any other way to collect waste?Bins of recyclable material contain 10% of wrong or non-recyclable material and recycling company has to spend money for its disposal.How can we reduce percentage of wrong or non-recyclable material?Bins of recyclable material contain 10% of wrong or non-recyclable material and recycling company has to spend money for its disposal.Can we sham use of these wrong or non-recyclable materials? -Some materials like used polythene bags can be reused as trash bags in houses for trash cans. In this way consumer can reduce the use of non-recyclable material.Bins of recyclable material contain 10% of wrong or non-recyclable material and recycling company has to spend money for its disposal.How can we reduce cost for disposing non-recyclable waste?Trigger 2 change the explicit definitionContainers of reusable materials are contaminated with non- reusable materials that are in fact, expensive to dump.Trigger 3 Making opposite sentenceHow to work bins of recyclable material contamination free, thus company has to spend no money for its disposal?Trigger 4 Use relaxing constraintsBins of recyclable material are never contaminated and there is no cost for its disposal. This technique helps us to think in different way. It motivates to develop a method so that recycle bins never get any contamination. Trigger 5 Replacing persuasive wordsThe problem statement implies that we on the face of it want zero contamination of recyclable waste so that company has to spend no money for its disposal. Thus, if we could avoid contamination at source by marking the bins and classifying non-recyclable and recyclable waste for consumers.Trigger 6 Expressing words in the form of equation This statement can be uttered in equation form Contamination in recyclable bin is directly proportional to presence of non-recyclable material. Therefore, By replacing, equilibrium sign (with proportionality constant (k). This trigger helps us in thinking in alternative way. What factors affect the value of k? How can we minimize the presence of non-recyclable material? Proper tagging of bins, classification of non-recyclable materials and recyclable materials for consumers, reducing use of non-recyclable material etc. can help in reducing contamination of recycle bins.ReferencesMoldes, Y.
