Recycling nutrients from household wastes

Project

Recycling nutrients from household wastes

Our ambition is to analyze nutrient flows in cities and the recycling of these nutrients back into the food production sector.

Urban and peri-urban areas are large sinks of nutrient elements and metals in household wastes, which create a range of unwanted effects.

This project aims at recycling these elements back into the food production chain. Thereby, it contributes to solving the problem of excess nutrient elements in cities. At the same time, it will save fertilizers and thereby contributes to saving scarce nutrient reserves in the earth crust for future generations.

We have quantified nutrient recycling in the European Union, and have identified a range of options for improving nutrient recycling and use efficiency.

Also, we have carried studies on recycling of nitrogen and phosphorus in Beijing and provinces in China.

Currently, we work on the recycling of nutrients in urban and peri-urban environments in Ethiopia.

Application

Our ambition is to analyze nutrient flows in cities and the recycling of these nutrients back into the food production sector.

We analyze options for improved recycling, and make business plans for these, together with local partners.

We believe that improved recycling of nutrient elements in cities is a key sustainability aspect, both economically, socially and environmentally
