The volumes of agricultural plastic waste (APW) generated are continuously rising, creating the need for sustainable management, especially in countries with large agricultural areas. This paper proposes a location allocation model for the establishment of centers for process and recycling of APW, presenting an enormous opportunity for the plastics...

Agricultural waste mapping is an indispensable tool for the development and adoption of sustainable waste management practises in the agricultural sector. Current practices of agricultural plastic waste (APW) management in countries with large agricultural areas and thus high generation volumes of APW include uncontrollable disposal in fields or ne...
Article
Half of the world’s population has been under lockdown to prevent the spread of COVID-19 pandemic, leading to a large shift of activities from offices to homes. Despite the inefficiencies exposed on the reliability of critical systems such as the energy system, this unprecedented situation also revealed opportunities for enhancing sustainability. T...

Project
Youth Employment Network for Energy Sustainability in ISlands aims to reduce the target group's unemployment by creating green jobs in islands. The project directly addresses the Fund’s principles and priorities by targeting young people between 25-29 who are also NEET. By reducing the focus group to this age group and specific requirements, the partners aim to support the discouraged young people who have stopped looking for work and are therefore socially excluded. Furthermore, embracing the Smart Islands Initiative and its principles of bottom-up approaches for innovation in islands. The project puts transnationality at its core as it recognises the commonalities amongst islands around Europe and understands the potential of exchanging good practices and joint endeavours.

The project “Design and manufacturing of a novel Low-Density Polyethylene (LDPE) Film for the construction industry, using recycled agricultural plastic waste (APW) aims to the design and manufacturing of an innovative, environmentally friendly and economically viable Low-Density Polyethylene (LDPE) film (Recy-Film) for applications in the construction industry. The main innovation and environmental aspect of the proposed product is the raw material to be used, which will be recycled agricultural plastic waste (APW), delivering a green building material which can be considered for green public procurements (GPP). Recy-Film will essentially replace the existing LDPE film product of Elysee, whose current production line uses virgin, fossil fuel-based materials. LDPE films are installed in buildings as vapour barriers, to reduce weed growth, and as a separating layer to accommodate differential movements. The choice of construction LDPE films was selected due to the contamination of APW with chemicals, a fact that forbids its exploitation either for potable water pipes or for irrigation plastics. For the manufacture of the RecyFilm, a pilot recycling unit, which will be able to handle 6 tonnes of APW on a daily basis, will be installed at the industrial facilities of Elysee. The project will also investigate the supply chains of APW from the source to the recycling facilities for the design of a comprehensive collection system that will be adopted by Elysee.
Project
The "Active Building Temperature Adjustment Mantle" is an innovative product in development by CrossWise Ltd within the business innovation sponsorship framework. This product is a complete structural system which consists of a gap shell in which temperature-controlled air will be recycled. The air temperature regulation will be achieved through a heat pump connected to a geothermal system, thus ensuring the necessary conditions of thermal comfort inside the building by utilizing renewable energy sources. The air will circulate freely or forced inside the shell, depending on the temperatures prevailing outside the building and the external structural element's solar exposure. Free circulation will be achieved due to the temperature inside the shell, while for forced circulation fan elements will be utilized, where required. Also, the materials used for constructing the "Active Building Temperature Adjustment Mantle" will differ depending on the application (home, commercial building, industrial building).
