All the concepts indicated in this document are introduced to Sri Lanka during last last decade and therefore the policies, programmes, projects and strategies have been recently introduced and implemented and so results are pending. To strengthen up these kinds of projects, more attention should be given to conducting awareness programmes to industries, training of relevant officers involved in these fields, providing modern equipment to carry out research and other activities and constructing suitable laboratories and other facilities. Being a developing country, Sri Lanka cannot afford to drive enough resources to these fields and therefore external financial support and technical assistance is highly required.
