WASCON (The International Conference on the Environmental and Technical Implications of Construction with Alternative Materials) has been held every three years since 1991 and provides a forum for exchange of ideas and current research nationally and internationally on the use of waste, industrial by-products and other recycled materials in construction. An important scientific base for the implementation of alternative materials is given by the numerous contributions to the WASCON conferences.
In addition to our regular WASCON conferences, ISCOWA is also interested in organizing other seminars and conferences related to our fields of interest. In case you have a good idea, please do not hesitate to contact us via our contact form!
