Disclosed herein are mineral-based composites that comprise gypsum, syngenite, brucite and a hydrated magnesium sulphate mineral, and which are adapted to degrade when buried. Also disclosed herein are mineral mixtures which can be used to produce the mineral-based composites, as well as products, such as plantable containers, formed from the mineral-based composites and which degrade when buried.

A method for decomposing struvite comprises dissolving of a feed material comprising struvite in a mineral acid. Thereby a solution having an acid pH is formed. Magnesium is removed from the solution. The removing of magnesium comprises increasing a pH of the solution to a pH in the range of 4.5 to 6, precipitating magnesium compounds that do not comprise ammonium, and separating the precipitated magnesium compounds from the solution. Thereby, the solution, after the removing of magnesium, comprises an ammonium salt of the mineral acid. An arrangement for performing such a method is also disclosed. Also, a method and arrangement for recovering at least nitrogen from waste material, based on the decomposing of struvite are disclosed.

A method is provided for producing functionally improved carbolime from carbolime and the use of the functionally improved carbolime as a filtering aid, as filler, as lime fertilizer or as adsorbent for the adsorption of dyes.
