Except Integrated Sustainability is a collective of experts that realize sustainable business, industry, policy and urban environments. Except’s Polydome Project is a revolutionary approach to greenhouse agriculture that offers the possibility of commercial scale, net-zero-impact food production.
The Polydome system strategically interweaves a wide variety of crops and animals, taking advantage of every inch of the greenhouse while eliminating the need for synthetic fertilizers and pesticides. With its high yields (60 – 90 kg per square meter), and diverse outputs (over 50 crops, two mushroom varieties, chickens, eggs, fish, and honey), even a small Polydome system can provide a richly varied food supply for a large population. Though it uses advanced greenhouse technology, Polydome’s true inventiveness lies in a non-technological strategy: it maximizes food production and variety by operating more like a self-maintaining ecosystem than an industrial farm. Partners in research and development include InnovationNetwork, SIGN, Koppert biological systems, Technokas & Bode projecten, Fytagoras and Wageningen UR. The Polydome Book contains a full overview of the inner workings of Polydome. It can be downloaded for free from here.
