Q5. For reducing, which means to minimise usage, i would probably reduce watr usage by having a shower instead of a bath. For reusing, i would probably use the shopping bags from the supermarkets to act as temporary rubbish bins. Finally for recycling, i would make the effort to place newspapers and bottles (etc.) in a corner of my house and bring them to the recycling bins downstairs to recycle them.
Q6(a). There are numerous concerns regarding to the fortnightly bin collections scheme. Such are the bad smells and problems with vermin resulting from the waste being stored for a longer time, worsen the problem of fly tipping and the concern of recycling bins contaminated with household waste.
(b) Concerns with the use on incinerators to burn rubbish are the concerns that these incinerators pour cancer-causing chemicals, also known as carcinogens out of their chimneys.
Q7 (a) Scotland had the highest reccling rates in the UK at 27.6% (of household waste recycled ) while Wales had the lowest recycling rate at 21.9%.
(b) The number of recycling bins, economic wealth and education provided on recycling could have differed with lower recycling bins, more economic wealth and less education provided on recycling in the Wales.
(c) Some form of reward (not having to pay taxes, monetary rewards etc.) could be implemented for households that has the highest recycling rates.

Waste Management in the UK-Recent Developements
Q1. The two reasons why the amont of rubbish in UK has become a major issue is because of 2 points'
1. Over-consumption
2. Excessive disposal
As a result of the increasing wealth in the MEDCs, coupled with rapid advancements in technology, it has made people more prone to throwing precious materials away without reconsidering. For example, rather then repairing old electrical goods, people would rather buy the latest models because of the convenience and cheaper prices. Resulting in non-renewable sources which could be reused or recycled, for example metal, to be thrown away.
The geology of the UK (UK has many large holes which could act as landfills) has also contributed to our habits of excessive disposal. However, these landfills are diminisig and so must the disposal of waste generated by humans.
Q2. Though these landfills has ben constructed to meet high safety standards, they also run a high risk of leaking chemicals, heavy metals and bacteria into the soil and water table. Also, organic waste would break down or decompose into leachate, which is a high poisonous liquid. All these are the possible occurings can could pollute the nearby rivers.
Q3. The main gases produced by a landfill site are methane and carbon dioxide. Methane is a gas that can be burned easily. If a landfill is covered after use, this gas will slowly seep through the earth covering and dissipate into the atmosphere, causing a long-term source of pollution and possible irritation for the local population. Until the landfill site has settled and the gas production has died down there is no way of reclaiming the land for building purposes, although the planting of trees and grass is possible in the interim. The production of gas will probably continue for around 20 to 30 years in many cases from a landfill site, with a gradual reduction after about 10 years. Such figures will vary naturally, depending on the composition of the waste and the temperature in the area.
