This project aims to quantify Sweden’s potential to recycle nutrients in manure, human excreta and other organic waste back into food production and look at the logistical implications of recycling from a cost and transport perspective at both the national and regional scale.

Building on optimization around nutrients, we are now looking at how such organic waste recycling interfaces with energy production (biogas especially), animal welfare (e.g. mobile slaughterhouses), and aquatic biomass harvesting for eutrophication remediation in order for Sweden to meet multiple sustainable development goals at once.


This work has important implications for policy decisions for food and agricultural severity and environmental sustainability, but also for company profitability.

We have thus partnered with stakeholders in Region Östergötland, along with other research teams at LiU, to coordinate and co-develop relevant questions, datasets, and outputs with the community.

Nutrient recycling in Pakistan

This project focused on the capacity of recycling organic waste.

Planet earth and recycle symbol.In this project we were using similar methods to those developed in the Swedish biobased economy project, this project focused more on the capacity of recycling organic waste to and meet other SDG:s (including sanitation and green energy production). Professor Uno Wennergren was leading this project.
