MACRO – Food in robust circular systems

The organic waste from the households, food and toilet waste, contains resources such as nutrients and organic substances that should be returned to agricultural land and used for producing renewable energy. Sustainable attractive cities require the utilization of society's waste and conservation of water.

There are several ongoing initiatives developing technical solutions for large source separating systems, development of treatment solutions that ensures the quality and increase opportunities for better recycling systems. Allthough experiences of completing the recycling system and being in operation for some time, are few. Large-scale recycling wastewater systems in urban areas – where the city and agriculture are connected – has great potential to be replicated globally.

The project Food in robust circular systems is aiming at developing systems and technologies for the densely populated city using Stockholm Royal Seaport Stockholm and H+ Helsingborg as pilots. During the project time, houses and local infrastructure for managing food waste and wastewater streams will be finalized.

In addition the development of a source separated wastewater system in a rural area outside Västerås will start. A pilot encompassing a few properties will be completed where transport and collection systems will be tested.

Systems and organizational solutions for the disposal and recycling of plant nutrients, including development of business models, regulatory framework, economics and conditions for utilization, will be developed in collaboration with wastewater and waste companies, technology providers, the agricultural sector and academia.
