Earth’s natural resources are finite and should be used in a rational and balanced way. To be environmentally sustainable, resources must be efficiently and effectively managed. In waste streams these can be repaired, recycled, reused. The recycling provides a link between reuse and mitigation of environmental problems saving resources and producing new products providing a win-win and wider solution that enables more efficient use of resources, stimulating the growth of economic and social development. The circular economy is one in which products are recycled, repaired or reused rather than thrown away, and in which waste from one process becomes an input into other processes. The literature complements circular economy between resource use, refurbishing materials, and economic growth. This paper is a comprehensive review of state-of-the-art of recycling and circular economy through the reuse of waste in the Curitiba city civil construction sector. It also reviews published review articles to highlight major findings, and analyses future research trends in construction and demolition waste.

In Mediterranean countries the olive oil industry produces, yearly, a huge quantity of pollutant wastes in a short time affecting soil and groundwater quality for their high content of phenols and wax. With the use of biological processes, we can transform these wastes into fertilizers for a sustainable agriculture. We used different methods anaerobic digestion, aerobic digestion, and crude agricultural waste management system to produce organic fertilizers. The obtained compounds were chemically analysed to verify if their characteristics fell into the marketability limits permitted by the current Italian regulation. Their effects on soil were subsequently assessed. Results evidenced that all the by-products obtained were suitable as fertilizers. They were able to increase soil organic matter, microbial biomass, and nutrients with beneficial effects on soil fertility, but at different extent. The best effects were in following order: compost, vermicompost, olive-pomace-pads and digestate. Considering that the different methodologies dispose different amounts of olive pomace (90% in composting, 70% in vermicomposting, 12% in anaerobic digestion and 5% in sulphur based fertilizer) in different time (4 months for compost, 3 months for vermicomposting, 1 month for anaerobic digestion and 1 day for sulphur-bentonite) and processing set-up, each method can be differently competitive for environment and/or agriculture. Composting and vermicomposting have economic advantage over other alternatives and have the greatest fertilizer effect even if the production time is longer than other two. Digestate use reduce the environmental impact of CO2 and CH4 emissions coming from the industrial fertilizer production process; it is rich in nutrients and can be obtained in a shorter time than compost. Olive pads production represents a crude waste management systems that reduce greenhouse gas emission in the atmosphere producing fertilizers able to generate, mainly in alkaline soils, a soluble zone of nutrients while minimizing leaching losses to the environment..
Babeş-Bolyai University, Romania
Time : 11:40-12:20
Szabolcs Fogarasi completed his PhD in 2012 in chemical engineering targeting the recovery of gold and silver from WPCBs. Currently, he is lecturer at Babes-Bolyai University being responsible of the following academic disciplines: Heat transfer and heat transfer equipments (HTHTE), Fluid mechanics and Mass transport. His research activities are mainly focused on the recovery of metals of economic and industrial interest from WEEE. He published more than 24 ISI scientific articles and 1 book in the field of HTHTE. He participated in various national and international projects emphasized on environmental issues such as technical and economic assessment of fossil fuel based power generation and recycling and treatment of e-waste.
In the recent years, recycling technologies were focusing on the recovery of Cu from waste Printed Circuit Boards (WPCBs), due to the high economic potential and eco-toxicity of copper found in relatively high concentration in WPCBs. However, many recycling technologies do not offer an overall treatment of WPCBs, leaving behind unprocessed fractions like WPCBBs (Waste Printed Circuit Base Boards = electronic component free WPCBs) which could be used for further Cu production. Therefore, the current study presents an original and environmental friendly technological solution for the separation of Cu and non-metallic fractions found in WPCBBs followed by the recovery of a high purity metallic Cu through electrochemical processing. The obtained results revealed the influence of the main operating parameters (current density, temperature, etc.) on the most important technical key performance indicators. One of the major advantages of the developed process consists in the recycling and regeneration of the materials used in the process, reducing significantly the use of auxiliary materials and the amount of new reagents fed to the process. Based on the obtained results it can be concluded that the separation of high purity Cu and non-metallic fractions found in WPCBBs has an overall low environmental impact and high efficiency.

Town of Naryn is a poster child for recycling and creating sustainable environment. In the last 10 years the town’s population has grown from about 35,000 to 53,000 with little planning to address the population’s needs for civic services including recycling and garbage collection. The problem is inflamed by open garbage burning; some garbage (batteries etc.) is poisonous, and when burnt, emit poisons in the atmosphere. Additionally, the coal burning power plant further pollutes the environment. This has negative health consequences for citizens. If the citizens are unhealthy, their productivity suffers negatively impacting on economy and civic life, exacerbating poverty. Children are particularly vulnerable when inhaling noxious fumes that inhibit their physical and mental growth.
Methodology to address garbage sorting and recycling: Naryn should introduce garbage sorting at residential and commercial points of garbage generation. This greatly facilitates recycling and makes the process efficient. Since this will be a new concept for Naryn citizens, it is imperative to produce and distribute illustrated brochures in local language for the citizens; brief infomercials will also help promote recycling. Good venues to introduce recycling concept are schools (primary and secondary), colleges, clinics and hospitals. Local garbage collection personnel will need training to spot and pick up sorted garbage.
Physical requirements: Sorting out garbage at points of generation require separate containers. This is easily accomplished by providing each household and commercial point of collection with different color-coded containers.
Benefits of Recycling: Once garbage sorting is implemented, it creates a win-win situation. Garbage, when properly sorted out, becomes a valuable commodity, e.g. vegetable and fruit cuttings can become compost for backyard gardens. Paper, glass, and metals can be recycled. Recycling will improve the quality of environment and consequently quality of life, including healthy citizens.
