The article presents design and investigation of foamed geopolymers as a green material that is dedicated to the circular economy. For the geopolymer synthesis as a raw material main waste form two Polish coal mines ‘Wieczorek’ and ‘Staszic’ were applied as well as a by-products from energy production – fly ash form ‘Skawina’ Power Plant. The aim of the research was to prepare lightweight materials using various foaming methods. The main issues that were addressed during the research were related to the selection of the most appropriate foaming agent and the optimization of process parameters (temperature, time, mixture components). As foaming agents, hydrogen peroxide, aluminum powder, and a commercial frothier for foam concrete were used. During the sample preparation process, stabilizers in the form of polyglycol and cellulose were applied. The tests carried out allowed to determine the two most optimal foaming agents as: hydrogen peroxide and aluminum powder according the physical and thermal properties of obtained materials. Attempts made with a commercial frothier for foam concrete did not allow satisfactory results to be obtained.
