The aim of the project is to use various waste and side streams generated in society to produce new raw materials. The project will develop a unique concept of circular economy ecosystem combining anaerobic and hydrometallurgical process to efficiently produce energy, organic acids, fertiliser and rare earths from local waste and side streams. The project utilises the anaerobic fermentation process in a new way, allowing bio-waste to produce organic acids in addition to biogas. This will be done by optimising the acid phase of the anaerobic process, where the Resource Centre has long-term expertise in several projects. The residue of the anaerobic process will be utilised by combining power plant ash to obtain a recyclable raw material suitable for fertiliser use. The organic acids produced can, after purification, be used as industrial raw materials or further recovered to recover metals from electronic waste. The University of Jyväskylä has extensive experience in the recovery of metals using hydrometallurgical methods, and the recovery of organic acids in the treatment of electronic waste has been developed in an earlier ERDF project (KITA, research platform for the circular economy, 2019-2021). The concept of circular economy ecosystem developed in this project will be piloted by Natural Resources Institute Finland and the University of Jyväskylä towards the end of the project.The solutions and results of the project will be widely communicated so that the target companies (electronic scrap recycling, biogas and energy sectors) will receive up-to-date information on the activities of the development project. The project will explore potential users of manufactured recycled products as well as commercialisers of developed processes, who will be involved in the project by organising a Circular Economy workshop during the project. The workshop will involve companies in the subject area of the project and allow the results of the development to be applied in a wide-ranging manner. The expertise of the companies involved in the development project will be used to support the development work, which can take into account, for example, the functioning of the processes in different existing plant solutions. In addition to new expertise, the project will produce new business opportunities in Central Finland and strengthen local self-sufficiency for a wide range of raw materials. When the necessary raw materials are manufactured internally from Finland’s own secondary flows, dependence on global production chains decreases and can be safeguarded even in crisis situations. Virgin natural resources are also saved and the carbon footprint of products is reduced when recycled raw materials are used. The project will result in new growth and self-sufficiency in raw materials, which will have a significant impact on recovery from the COVID-19 crisis.
