Evidence-based policy-making offers the potential to strengthen the quality and effectiveness of environmental policy at each stage of the policy cycle.

Introduction:
According to Davies, 2004, the evidence decision making policy is the approach that helps the masses informed about the decision, policies, programme and project by putting the evidences in the policy and making it the heart of the policy development and the implementation. Evidence based policy making is that approach that promotes the particular method for producing particular evidence in the process of the policy making. It helps in assessing the policy, in term of what works. The evidence based policy making is about 10 years old. And it is used widely by the government in its environment policy making. It is generally consider that the policy Making based on the evidence is generally a good process. But this practice is very challenging and is still evolving. The link between the researcher and the policy maker is still need to be stronger, as it is required that the policy maker should tell the demand of the evidence in much advance and the researcher should be able to do it routinely. But still it is the area of weakness.
Policies are all around us and indirectly or directly they affect many aspect of our life often we ask our self that what is the procedure of formation of these policies, why politicians have decided to implement that policy, and not another one. In formation of any policy some international agreement, the laws and agreement, a macro economic plan and some politician’s interest may involve. In last few years citizens becoming an active part in the policies do not wait some obscure decision for top down, but they wish to know and to be informed about the decisions of government and their action. They also want to receive the explanation before accepting any decision. In present context public is not a subject but an active part in democracy in this sense public participation have become crucial for continuation of democratic process as well as to avoid opposition phenomena. That is why now policy making is more accountable and evidence based rather than based on supported opinions. In 1997 the concept of evidence based policy making was introduce. The idea of creating polices on the bases of available research and knowledge on the specific issue is not new however we need to deepens into the concept and its peculiarity.

In this paper it is discussed the evidence based policy making effectiveness and strength in terms of environment policies. The two environment policies are discussed in detail to have a clear picture of the topic. 1. Waste to resource policy: Environment protection (waste to resources) 2010-2011 has been introduces by authority of the UK. That includes six part and five schedules related to management of waste in such a way that they optimise up to the level of resources. This policy also refers the safe collection handling recycle and reuse of domestic as well as bio medical waste.

The objective of this policy is to achieve the economical and sustainable waste management by applying the waste management hierarchy consistently with the principles of ecology.
In order to meet the waste management objective we should promote best practise an accountable waste management, however we should not avoid the regional differences within the state because the quality and quantity of waste vary from location to location. The evidence based management policy (waste to resource) includes effective recording, monitoring and reporting system with respect to waste transport, resource recovery and waste disposal. In addition, it should also promote environmental responsibility, waste minimization and waste management within the community by promoting and education of people about waste management practises.
Local trends of waste generation in UK: Nearly 12 million tonnes of waste was generated and processed by environment agency in year 2009. In which about 3.3 million tonnes (28%) of this total was inert waste while only two lack tonnes (2%) was hazardous waste. The majority of hazardous waste was waste water which was treated by using asbestos. UK has to permit hazardous land site and the non hazardous site with the capacity to dispose of capacity. To dispose of stable non reactive hazardous waste
