Rohering, Europe's largest home composting pilot project of 2019 started in Tallinn. During the project 150 fast composters will be distributed to residents of the capital. The project will determine by how much sorting biowaste will increase with the help of innovative technology. The project is being carried out by Wastefox, the Estonian developer of fast composters, and Tallinn Waste Center.
Based on the results of the pilot project Wastefox plans to create a method for distributing high-speed composters to EU governments next year that will help them meet the Union's goals to recycle 50% of municipal waste.
Most composters are distributed among randomly selected private houses in the Haabersti district. For four months the Tallinn Waste Center will continuously weigh mixed municipal waste bins from the participating households to determine if the amount of biowaste in the municipal waste has decreased after the distribution of the composters. Households have to pay
"For city dwellers quick composting is a new exciting tool that will help them get used to sorting bio-waste," said Jonathan Oras, Rohering's project manager. “If composters can increase the number of bio-waste sorters it will help reduce the amount of bio-waste that reaches landfills, thus reducing greatly the amount of emitted greenhouse gases. Additionally better sorting of bio-waste will help waste recyclers recycle plastic more efficiently,” added Oras.
“Tallinn has already achieved good results in waste recycling. The participation of the Tallinn Waste Center in the Rohering project is a step towards reducing the amount of bio-waste in mixed municipal waste, but also giving residents the opportunity to produce necessary humus for their own home garden,” explained Kristjan Mark, the director of Tallinn Waste Center.
Produced and developed in Estonia, the quick composter decomposes food waste up to 10 times faster than conventional compost heaps. The waste is not accessible to animals, does not emit odors from the composter, and works with organic microbes that accelerate the decomposition process. The end product of the Wastefox Compost can be used to fertilize plants in the garden.
"After the Rohering pilot project we plan to reach a strategic partnership with at least five local and regional authorities in Estonia and other European countries next year, thus helping residents to sort their bio-waste more carefully," Oras added.
Researchers of the Estonian University of Life Sciences have contributed to the development of the Wastefox composters. An accelerated process in a composter allows a 50-liter composter to transform up to 500 liters of bio-waste into humus per year. The heat needed to decompose the waste is aided by the special insulation around the box. The resulting humus can be used as a fertilizer in the garden.
Experts from six organizations - Wastefox, Tallinn Waste Center, NGO Cleantech Forest, Estonian University of Life Sciences, Ministry of the Environment and the City of Tallinn - are helping to carry out the pilot project.
The pilot project takes place within the framework of the European Climate-Kic City
Challenge, the leader of European climate innovation, which was announced in 2018 by the Estonian NGO Cleantech Forest which promotes green innovation.
Wastefox (formerly Festera), the leader of Rohering, was founded in 2016 as a student company to manufacture indoor waste bins. In 2017, Wastefox also won the title of Best Estonian and European Student Company.
