Waste picker organizations (WPO) are a fundamental link in the integrated management of urban solid waste; however, despite being formally recognized, waste pickers still face unhealthy work conditions. Studies on occupational risks related to waste picker activities have been carried out in a qualitative way, but the quantification of occupational risks is an important research gap to fill. Additionally, an unprecedented comparison between waste picker risk perception and occupational safety technician risk assessment is presented. The risk perception of the waste picker was carried out through a cross-sectional interview study that surveyed 35 WPO by non-probabilistic sampling, and the results showed that waste pickers underestimated the occupational risks (i.e. noise, physical effort, improper physical arrangement, and inadequate use of personal protective equipment (PPE)), it was also possible to identify the necessary strategies to improve occupational safety. Occupational safety technician evaluations were carried out through quantitative analysis on site in 64 WPO. The results indicated the predominance of maximum risk intensity (Level 3 – from a scale of 0 to 3) for biological risk, physical effort, excessive pace, improper physical arrangement, and inadequate use of PPE in all operational activities. The main interventions should focus on implementing Work Accident Reporting, rearranging WPO layout, routinely providing information about importance of PPE use, and continuously developing WPO standards with periodic evaluations of occupational risks using a fractional scale.

The construction sector is one of the largest consumers of raw materials and energy, as well as a producer of CO2 in the European Union. To reduce environmental pollution and to preserve raw materials and energy, resource-efficient building elements must be designed. Even if laws demand resource-efficient product design in the building sector, there is no independent evaluation system for the resource efficiency of building elements (e.g., walls, roofs, floors). Such an evaluation should take the whole life cycle into account. The measurement of reusability and recyclability is therefore necessary. This article, therefore, describes the development of an evaluation system for reusability and recyclability to be included in resource efficiency assessment. Existing approaches and the special requirements of the building sector are considered. Finally, a practical example shows that the developed system is suitable for the assessment of reusability and recyclability. It can be used for the comparison of different construction methods or for the comparison of specific designs or products; thus, the evaluation system is helpful for architects as well as for product designers.

The paper discusses research results on waste governance and circular economy, conducted with waste picker cooperatives in the metropolitan region of São Paulo, Brazil. Two cases have been selected, from a pool of 21 waste picker organizations, to video document their grassroots eco-social innovations that have improved local waste management and the lives of the cooperative members. The videos support knowledge sharing with key actors in waste governance and the circular economy. Social grassroots innovation theory focuses on livelihood opportunities beyond the formal labour market, pursuing social inclusion by creating meaningful work for individuals who were considered left out and in vulnerable situations. Transitioning to sustainability necessarily goes beyond socio-technical innovations but rather integrates eco-social perspectives. After first introducing grassroots innovation theory and the concept of eco-social innovations the paper describes the empirical frame and presents two cases where organized waste pickers were successful in operationalizing innovations that address the circular economy and contribute to sustainability transitions. Key findings highlighted are cooperative governance, long-term partnership building, improved productivity and increased income.

Recovery of metals from former industrial areas (also called brownfields) and closed landfill sites, are critical for future sustainable development and reducing the environmental risks they posed. In this study, the feasibility of using bioleaching for resource recovery of raw and secondary raw materials from a former metallurgical site and deposit (PMSD) located in the UK was investigated. Determination of the physicochemical parameters (conductivity, pH, moisture and ash content) that can affect bioleaching performance along with metal content analysis were carried out. Field measurement were also carried out using a portable X-ray fluorescence (pXRF) spectrometer as a rapid measurement tool and compared with the induced coupled mass spectrometry (ICP-MS) results. Fe (469,700 mg/kg), Ca (25,900 mg/kg) and Zn (14,600 mg/kg) were the most dominant elements present in the samples followed by Mn (8,600 mg/kg), Si (3,000 mg/kg) and Pb (2,400 mg/kg). The pXRF results demonstrated minimal variance (<10%) from the ICP-MS results. The preliminary assessment of bioleaching using Acidithiobacillus ferrooxidans at 5% pulp density with 22 g/L energy source and 10% (v/v) inoculum at pH 1.5 showed that 100% of Ti and Cu, 32% of Zn and 24% of Mn was recovered from the sample material, highlighting opportunities for the recovery of such metals through bioleaching processes.

For several decades, Liquid Crystal Displays (LCDs) have been widely used in televisions, laptops, mobile phones, and other devices. Nowadays, liquid crystals (LCs) represent an important economic value of the recycling system of LCDs. The reuse of these organic molecules could become a profitable basis since it permits to preserve the value of these materials. In this context, the general objective of this work focuses on the recovery of LCs as well as on other valuable materials present in end-of-life LCDs. An orderly, manual LCD dismantling line is put into operation for differentiated recycling of electronic boards, cold cathode lamps that may contain mercury, polymers, metals, and other valuable materials. There is also an extraction line where LCD panels are opened and exposed to an ultrasonically activated organic solvent bath to recover LCs. The resulting solution contains LCs, solvent, organic and inorganic impurities. The LCs mixtures were purified and then characterized mainly by spectroscopic, chromatographic, and thermal techniques. A study of the influence of adding diamond nanoparticles at 0.05, 0.1 and 0.2 wt% to recycled LCs was also performed using dielectric spectroscopy. Dielectric properties of LCs were measured at room temperature, using an impedance analyzer in the frequency range from 0.1 to 106 Hz.

During an earthquake, a large amount of waste was generated, and many Asbestos-Containing Materials (ACM) were unintentionally destroyed. ACM is a mixture of cement matrix and asbestos fiber, widely used in construction materials, that causes serious diseases such as lung cancer, mesothelioma and asbestosis, as a consequence of inhalation of the asbestos fiber. In order to reuse and recycle Post-earthquake Building Waste (PBW) as secondary raw material, ACM must be separately collected and deposited from other wastes during the recycling process. The work aimed to develop a non-destructive, accurate and rapid method to detect ACM and recognize different types of PBW to obtain the best method to correctly identify and separate different types of material. The proposed approach is based on Hyperspectral Imaging (HSI) working in the short-wave infrared range (SWIR, 1000-2500 nm), followed by the implementation of a classification model based on hierarchical Partial Least Square Discriminant Analysis (hierarchical-PLS-DA). Micro-X-ray fluorescence (micro-XRF) analyses were carried out on the same samples in order to evaluate the reliability, robustness and analytical correctness of the proposed HSI approach. The results showed that the applied technology is a valid solution that can be implemented at the industrial level.

Waste management is a crucial priority issue for all countries in this environmentally conscious era. Proper waste management of disposable diapers is one of the issues at the forefront. The unprecedented growth of the world urban population has left many cities grappling with disposable diapers clogging landfills. It is a problematic issue that if not mitigated could overburden existing waste management systems. This mini-review article aims to critically review relevant life cycle assessment studies (LCA) on single-use disposable diapers and the environmental impact incurred at each stage of its life cycle. Different technical and non-technical disposable diaper waste management approaches have been explored in literature, but studies directed towards pyrolysis conversion of disposable diapers post-consumer waste are notably very scarce. The review further examines the potential of pyrolysis as an end-of-life waste management option for disposable diapers. Finally, this study highlights gaps in the literature and recommends the scope for future research.

In recent years, industrial and civil projects and policies usually include improvement of sustainability performance. Many instruments, tools, and targets exist to assess environmental performance and sustainability. Life cycle assessment is one of the most used and robust tools. The aim of this analysis is to evaluate if different approaches can result in different environmental sustainability assessment results. Some case studies based on previous research are listed. Results of selected tools – carbon footprint, design for disassembly criteria, environmental product declaration targets, national targets of the Italian recovery plan, sustainable development goals, green chemistry principles, waste hierarchy objectives, material circular indicators – are compared to the outcomes of the life cycle thinking approach. The assessment of environmental sustainability performance of projects appears to depend on the tool used. Thus, the role of selected instruments, subjective choices, fair communication of results, and sustainability definition are investigated. Finally, future areas of study are indicated.
