Our latest project is the Klasse Urbeen. It has been designed for and with Stichting Buurtcompost in the last few months. From september 2017, the first three Klasse Urbeens will be used in combination with an education program. In the meantime, they are being tested at the Hogeschool van Amsterdam. A group of five students will run tests to see if the size of waste or the presence of worms is affecting the compost-process. This three-month-test is being supervised by Arie van Ziel and Peter-Jan Brouwer (Stichting Buurtcompost). Beside looking at what’s inside the Urbeen, they will test which material is most suitable for the Klasse Urbeen.
