Abstract:
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.

Abstract:
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..

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.
Abstract:
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.

Abstract:
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.

Terracina Zero Waste Committee, Italy
Title: Terracina Zero Waste Committee, Italy
Biography:
Filomena Compagno is an Italian Zero Waste activist. She is part of the Terracina Zero Waste Committee and Observatory and she is the ecological referent of the Istituto Comprensivo Milani of Terracina, where she teaches French and is daily engaged in Recycling, Reducing and Reusing. Together with the local Zero Waste Committee she organized important ecological events, she monitored the separate collection in local schools and she promoted the campaigns for the use of the canteen in spite of plastic bottles, for the reduction of packaging in local bakeries and for the collection of plastic toys on Terracina beaches. In 2017 she took part as a speaker at the Annual Zero Waste Workshop in Capannori (Lucca). She is writing a book on Zero Waste Schools and in December 2018 she will take part to the EWWR Decennial in Rome as Action Developer.
Abstract:
Terracina is a bath town of 46.000 inhabitants. In 2015 it became a Zero Waste Municipality with a Zero Waste Observatory. In the same year Terracina adopted the door-to-door collection reaching 59,17% of Recycling, while in 2016 it reached 73%, becoming the first “Comune Riciclone” of Latium. How was it possible to reach this important goal? It was possible because the local City Adminitration works together with citizens, local sanitation transfer station and associations, including our Zero Waste Committee. In order to improve Recycle the Municipality of Terracina created separate waste collection centres and an “Eco-point” at the harbour where fishermen can bring plastic fishing waste, it placed recycling bins in town, it adopted Junker app, it distributed free compost bins and it forsaw a waste awareness raising campaign. In this scenario our Zero Waste Committee has a leading role. We are daily engaged in Reducing, Reusing and Recycling. In 2016 we monitored and encouraged the separate collection in every school of our municipality, contributing to Terracina “Comune Riciclone”, and we promoted the campaigns for the use of the canteens in spite of plastic bottles, in 2017/18 we promoted the reduction of packaging in local bakeries and the collection of plastic toys on Terracina beaches at the end of summer. We organised book and toy reuse markets in 2017 EWWR and Zero Waste events. In order to sensitise students, teachers and families we organise Zero Waste training courses at school. Thanks to Zero Waste Committee engagement the “Istituti Comprensivi” of Terracina are now all “Eco-schools”. Finally, we administrate Zero Waste groups on Facebook because it is important to spread ecological issues and beacuse we are open to debate. That’s for all these reasons that I think we can talk about “The case Terracina” for what concerns Reduce, Reuse and Recycle.
Esher Hsu
National Taipei University, Taiwan
Title: Cost-benefit analysis of agricultural waste recycling in Taiwan
Biography:
Esher Hsu is an associate professor at National Taipei University in Taiwan. She specializes in sampling survey, environmental statistics and agricultural policy. She has participated in several projects on solid-waste recycling funded by the EPA in Taiwan and has developed a Taiwan Agricultural Policy System (TWAPS) funded by the Council of Agriculture in Taiwan. Now her research focuses on waste recycling and renewable energy.
Abstract:
Along with the development of circular economy, the waste recycling of agriculture in Taiwan has received much attention. Major recycling types of agricultural waste including energy recovery and compost which can not only reduce waste pollution, but also create economic benefits. However, the cost efficiency of agricultural waste recycling has been argued in Taiwan. This paper intends to evaluate the feasibility of recycling agricultural waste in Taiwan through cost-benefit analysis of different recycling types, and further provides policy suggestions of recycling. The study results show that the cost of energy recovery of agricultural waste is about twice of the benefit for biogas power plant in Taiwan; whereas, compost recycling has relative low cost but the quality of compost is unstable for fertilizer use. Moreover, high investment costs of biogas power generation equipment and relatively low of the grid-connected electricity price could not provide investment incentives for energy recycling of agricultural waste which thus reduces recovery efficiency of Taiwan's waste energy recycling. Study results suggest that (1) adjusting the FITs of biogas power generation to compete with other renewable energy, such as solar photovoltaic to increase the energy recovery efficiency, (2) improving the quality of compost through technical reform to increase recycling efficiency of compost.

He has published more than 30 peer-refereed articles in leading journals and international proceedings in environmental engineering.
Abstract:
Marine and river sediments have been subject to urban, industrial, agricultural and various anthropogenic contaminations. High concentration of nutrients and pollutants are often found, resulting in sticky sediment. One of the common practices to deal with the sediment in Hong Kong is regular dredging and followed up either marine dumping or landfill disposal depending on the contamination level of the sediment. Recycling sediment is not a common way, not until recent years. In view of the possible marine contamination and scarcity of land for landfill, beneficial reuse of dredged sediment is encouraged as a sustainable alternative in Hong Kong. For feasible engineering applications, on-site application of sediment means the saving transportation and disposal costs.
Fabian Diaz
RWTH Aachen University, Germany
Title: Process concept based on pyrolysis for integration of Shredder Light Fractions (SLF) in the recycling of waste electrical and electronic equipment
Biography:
Diaz has completed his bachelor degree in the field of Electronic Engineering at the Universidad Pontifia Bolivariana in Colombia and later his master in Metallurgical Engineering at the RWTH- Aachen University in Germany 2013. Since August 2013 he has been working as research assistant at the institute IME Process Metallurgy and Metal Recycling in the field of WEEE recycling.
Abstract:
Yearly production of rest fractions like shredder light fractions (SLF) in the preconditioning of waste electric and electronic equipment (WEEE) accounts almost the 4.22% in a state of the art preprocessing company for this sort of wastes. This amount together with other shredder residues e.g. automobile recycling industry accounts the 4% of the total waste generated in Europe (2.5 billion tons). Considering not only the hazard to human health due to risk of exposition to different toxic materials like dioxins, furans and heavy metals due to wrong handling, but also taking into account the content of valuable metals like Cu, Ag, Au, Pd, is making recycling of such a wastes an important issue. Therefore, a research has been conducted in the last five years at IME-RWTH Institute, trying to find an economical, technical and sustainable solution. In this particular case, as indicated in Figure 1, a process concept based on an autothermic smelting stage of printed circuit boards, followed by a slag reduction stage using pyrolysed SLF from WEEE as reducing agent has been evaluated. Results has indicated that pyrolytic materials follows a different reduction path compared to commercial coke that makes the material appealing to the process. This mechanism uses the still presented organic carbon after pyrolysis with some oxides like Cu, Ni, Al oxides as catalyst materials to undergo e.g. the so called steam and dry reforming reactions to generate free hydrogen that acts as alternative reducing agent. This increases the kinetics and effectiveness of the reduction process in general by at least 30%. The process has been validated in demo-scale by treating 250 Kgs of SLF. The PCBs autothermic smelting as well as reduction process were conducted in the pilot Top-blown-rotary converter available at IME Insitute.
These results opens the opportunity to use SLF materials not only as energy carrier but also as an effective reducing agent for the copper industry.

Abstract:
Polyvinyl-chlorine (PVC) is a material with a wide range of utilities such as construction, packaging, medical materials, and the automotive sector. Because these materials have much time to disappear in nature, it is vital to utilize PVC chip wastes. Concrete was applied on the roads of the Northern campus of Hittites University. PVC chips obtained from door and window manufacturing shops have been added to the concrete mix of concrete bicycle roads. PVC chips were utilized in the concrete by eliminating 0,5 mm aperture size. PVC chips have been added into the transit-mixer from the concrete plant to the construction site. PVC chips were used in the mixture of concrete in the ratio of 1-3 and 5 kg/m3. The largest aggregate size in the mixture is 22.4 mm. The addition of PVC chip to the concrete mix reduced the precipitation value of fresh concrete from 190 mm to 150 mm. The addition of PVC chip has slightly increased the air void ratio of the fresh concrete. Hardened concrete tests, compression resistance, tensile splitting strength, and modulus of elasticity were performed. PVC has been compared with the additive control concrete sample. 5 kg/m3 PVC chip, which was added to the mixture, has reduced pressure resistance by about 11%. It can be stated that the PVC chip contributes positively to the tensile splitting strength and elasticity module values of the concrete. Apart from these tests, firstly, modulus of elasticity tests was carried out on 15*30 cm cylinder samples. Then, compression resistance and tensile splitting strength tests were conducted on the same samples. In the modulus of elasticity test, variations in compression and tensile splittings strengths of examples exposed to repeated compression loads were examined. After the test of elasticity modulus, the compression resistance and tensile-splitting strengths of the samples have decreased. It has been concluded that very thin PVC chip wastes can be utilized in a concrete mix.

Abstract:
With the technological innovation and market expansion, the update of electric and electronic equipment (EEE) is continuously accelerate. China is the largest emerging market region in the world with both global manufacturing and consuming market. Rapid economic growth, coupled with urbanization and growing demand for consumer, is expected to increase the consumption of EEE, thus increase the waste electric and electronic equipment (WEEE) rapidly in this region, posing a severe threat to the environment and sustainable economic growth. In view of the environmental impact induced by WEEE and the high residual value of the materials contained in WEEE, the research on reverse logistics and closed-loop supply chain with recovery attracts more attention. The first purpose of this study is to analyze the implementation of strategies and technologies of WEEE recovery, and mainly focuses on the current status of WEEE and corresponding responses adopted so far in China. Moreover, since 2015, “Internet+” recycling, a new recycling mode, has been developing rapidly in China. This new recycling program takes a revolution of the traditional recycling method, which implements the internet idea, technology, and mode into the way of recyclable resource
recycling. Subsequently, many recycling centers have developed a dual-channel reverse supply chain by introducing online recycling channels on the basis of offline third-party recyclers (TPR). Considering the regional differences in China, it is necessary to help recycling centers to formulate pricing strategies, so as to develop cost-effective recycling technologies. To solve the problem, a pricing model of recycling centers and the TPR in a dual-channel reverse supply chain in two different regions are formulated, and a case study is used to illustrate the proposed model. The results of the study will be able to supply more information on the sustainable development of “Internet+” recycling for the Chinese government and recycling centers.

Abstract:
Polylactic acid (PLA) is one of the most promising bio-based and biodegradable polyester, which can be converted into packaging and utensils; for example, cutlery, cup, tray, etc.; however it is brittle and expensive. Blending with thermoplastic starch (TPS) is a way to reduce the price of the final PLA-based products and to improve their flexibility. Although TPS/PLA blend is a biodegradable thermoplastic material, its recyclability is also important to meet sustainability. Until now, there is no any report relevant to the recyclability of TPS/PLA blend. Therefore, the aim of this research is to demonstrate the effect of injection-molded TPS/PLA blend scrap concentration on properties of the reformed TPS/PLA blend. TPS/PLA blend was prepared by a twin-screw extruder using a weight ratio of TPS:PLA of 60:40 and various concentrations of injection-molded TPS/PLA (60/40) blend scrap, i.e. 0, 20, 40, 60, 80 and 100 wt%. The blends were then converted into dumbbell-shaped specimens using an injection molding machine. The increased amount of scrap caused slightly increased tensile strength and elongation at break; however TPS/PLA blend with scrap concentration of 20 wt% had the highest tensile strength (24.2% improved). In addition, Young’s modulus and Izod impact strength of the blend decreased with increasing scrap content. Glass transition temperature of TPS/PLA blend decreased from 59.7°C to 52.4-57.5°C when scrap concentration was increased. The results suggest that TPS/PLA blend can be recycled and suitably used for making injection-molded products, especially for the ones without food contact such as jardiniere, flowerpot, shovel, basket, stationary box, etc.

Abstract:
The consumerism in the textile sector also causes an increase in textile waste. Compared to other wastes, most of the clothing and textile waste can be recycled. In addition to producing new clothes, rugs and cleaning cloth, insulation and filling materials, tar paper and panels are also used in the utilization of these wastes. In this study, jean trousers in used waste condition have been converted into fibers. Waste jean pants fibers are used in pumice aggregate briquette. The trousers made into fiber contain 97% cotton and 3% elastane. In 1800 kg/m3 pumice aggregate mixture, 2 kg/m3 ratio of waste jean pants fibers were supplemented. Production was made in briquette factory. Two (2) series of briquettes are manufactured with fiber additives and fiber-free additives. The number of briquettes produced in one batch in the factory is 156. On the samples produced, pressure resistance, density, size, surface control, and thermal permeability tests were conducted. The same operations were replicated by exposing the samples to temperatures of 200 0C, 400 0C, 600 0C and 800 0C. The waste jeans fibers have a possitive effect on the compressive strength of briquettes. Compressive strength of the control sample is 1,48 to 0,51 MPa. The compressive strength of the samples with fiber additive in waste jeans is 1,47 and 0,72 MPa. The average results were evaluated by testing six samples in each series. As temperature increases in all samples, compressive strength and density values are also decreased. According to the control sample, the density of fiber samples in waste jeans increased slightly. With the increase in temperature in the control sample, the samples have become more brittle and dispersed. Less dispersion has occurred in samples with fiber additive in waste jeans. The length of usage of the construction materials is longer than the length of use of the clothes. Therefore, the evaluation of textile waste in construction materials prevents waste from reappearing for a more extended period.
