The model estimates the market share of gypsum recycling systems in a given country. It can be used as an analytical tool by stakeholders to identify the causes that limit the rate of gypsum recycling in a particular country, as well as the solutions that lead to improve the situation. A total of six factors have been defined and combined into a mathematical model to determine the share of gypsum that is recycled, most of which neither the gypsum recyclers nor the European Plasterboard Industry can directly influence. The factors are grouped into four categories: technical, economical, legal and environmental. Finally, the model has been revised to make it applicable to any other type of construction and demolition waste.
