The main objective of these Guidelines is to improve waste management by offering updated and objective information about pre- and co-processing of waste in the cement industry. They contain knowhow and practical experiences gained in implementing pre- and co-processing since the first edition that served as a reference document in international agreements (e.g. Basel Convention for Hazardous Waste Treatment) and adaptation of various national guidelines. The Guidelines follow common understanding that avoiding and reducing waste is the best way of dealing with current waste problems all over the world. The extension of waste collection to 100% of the population and of waste fractions is notably a prerequisite to manage waste effectively in many countries. However, the Guidelines promote an approach that aims to reduce existing waste problems and at the same time to encourage the use of waste as an alternative source for primary energy and virgin raw materials in cement production. Wherever possible, the concepts of resource efficiency, circular economy, recycling and reuse must be given first priority. Improving waste management will take time. Reaching the status of an effective waste management solution in Europe has taken place over a period of 20-30 years. It has been supported by stringent legislation to monitor quality and emissions. Developing pre- and co-processing as a suitable waste management option requires also time and investments. Rigorous permitting and quality assurance procedures need to be applied. Pre- and coprocessing respects the waste hierarchy and does not contradict it, when these Guidelines are followed. In this context, it can be classified as a technology for energy recovery and mineral recycling. The key for implementation of these Guidelines and to achieve the maximum benefit from pre- and co-processing of waste in cement production continues to be close collaboration and co-operation between the public and the private sectors. Innovative techniques and technical knowhow are available and will be further developed by the private ector, whereas the public sector should ensure that environmental standards are maintained and health and safety regulations are applied and enforced. In addition ethical business conduct, good governance and social responsibility remain prerequisites for successfully implementing the Guidelines.
