In this SIS project, we aim at contributing to the future bioeconomy by providing new knowledge on sustainable use of organic waste resources as fertiliser. We will use microalgae for removing nutrients from liquid waste streams, and assess the effect of sorbents in biogas processes during digestate post-treatment and utilization. We also intend to identify a set of analytical parameters to predict fertilisation effects of waste resources compared with mineral fertiliser, and develop guideline models for balanced nutrition application in fertilisation plans. We aim at developing an unbiased analytical method for quantification of different plastic polymers in organic waste. This will permit a range of studies on sustainable waste treatment and quality assessment, as well as studies on fate and risks of microplastics and associated pollutants in terrestrial environments. Also, we will explore socioeconomic barriers for demand for and supply of waste resources as fertiliser. We will propose a framework to describe and compare waste resources in terms of their quality as fertiliser and impacts on the environment as a decision support for users and authorities.
