"<< Background >>Agricultural practices such as excessive use of fertilizers and chemicals have been causing soil degradation, salinity, health effects, reduction in soil biodiversity, atmospheric and water pollution, and climate change. Farmers generally use inorganic fertilizers due to their availability and scarcity of ready to use organic conditioners. Therefore composter project targets zero waste by evaluating organic farm and agricultural wastes, re-use of materials and promote circular economy. Compost production will help to develop sustainable agricultural systems with efficient use of resources. Using organic compost for plant production will be resulted in decrease chemical inputs to soil. Additionally it will increase soil carbon, promotes soil health and reduces climate change through carbon sequestrations in soils.<< Objectives >>The ultimate goal of the project is to contribute to the improvement of soil health as well as organic production through teaching composting process. The project aims to establish long-term cooperation and partnership relations among Turkey, Lithuania and Spain in composting sector, to develop the best practices on compost production conformant to EU quality and standards and setting up healthy information exchange, to design training programmes on sustainable compost production methods and putting these methods into practice, to train farmers and organise pilot exercises, and to implement some innovative composting methods.<< Implementation >>Composter project has different target groups, such as organic waste producers, local farmers and farmers’ associations, private consumers, environmental groups and organizations, Agricultural Faculty and Vocational School students, policy makers (local authorities and municipalities) and environmental NGO’s. Through the project activities, participating organizations and target groups will develop new skills, share traditional and innovative approaches and technologies in terms of compost production, and transfer these acquisitions to future generations. The target groups and stakeholders can transfer information in all participating countries, in line with the priority areas of the Erasmus + project call. The COMPOSTER team will act as a catalyst in this regard, leading the transfer of technical knowledge. The project aims to solve chronic problems experienced by farmers, from compost production to marketing, by developing the newest methods (training modules and strategies). With the in-class and e-learning trainings, compost farmers will be able to participate in the market or increase their competitiveness in the market. Scientists specializing in compost production will have the opportunity to establish a pool of experts. The COMPOSTER project will encourage the commercial growth of small-scale producers by facilitating the development of advanced production processes, ensuring production innovation and improving the marketing skills of manufacturers. Finally, considering that farmers and small-scale producers are the locomotives of the rural economy, the economic development of these producers means an increase in the general welfare of the society. Rural to urban immigration will decrease and unemployment will decrease by creating profits and constantly growing businesses. In the long term, it is expected that the capacity of the producers will be increased, the qualified workforce in composting will be increased, the producers will be able to integrate with commercial and international markets, access support loans, establish new national and international collaborations and increase stability.<< Results >>The project aims to develop four main intellectual outputs as follows;-The output 1 titled as ""Composting Methods Manual""-Output 2 titled as "" Marketing Tactics in Organic Compost Production""-Output 3 is ""COMPOSTER Documentary Film"" .For dissemination of project outputs, a virtual workshop titled “Workshop on New Innovative Technologies for Compost Production, Turkey” will be organized. Small-scale compost producers and young farmers, entrepreneurs and other beneficiaries who are starting to use compost in their agricultural practices will improve their position in the sector and have a more efficient market share. In addition to the trainings given in the classroom environment, the trainees who will participate in the practices to be carried out in compost collection and production facilities will also provide added value in the provision of qualified workforce."
