The establishment of an EPR database is critical in operationalising and formalising the management of EPR-related data. The EPR database allows e-waste flow tracking and EPR fee and recovery rate calculation while ensuring producers' information confidentiality and helping prevent counterfeiting activities.

The case study outlines the project’s efforts towards establishing this automation system in Nigeria in the following areas:

• Developing the EPR database: to manage producers’ market share data, calculate and collect the EPR fees.
• Registering Producers and products in the database: To ensure electronic and electrical producers are registered and to oversee the EPR operation.
• Securing the database: Enhancing producers' trust in the database and ensuring its confidentiality.

The study concludes with a summary of next steps and key learnings, emphasizing the importance of law enforcement, database registration, secure systems for producers, and encouraging the participation of producers in the database registration.

This study aims to predict human exposure to pollutants and heating load in buildings by developing a numerical model coupling heat and chemical transfers in the building envelope. The study characterizes the effect of temperature and air renewal rate on chemical emissions from building materials and human exposure. The results show that increasing indoor temperature by 10°C doubles the maximum indoor air concentration of volatile and semi-volatile organic compounds, leading to increased human exposure. The study also finds that higher air renewal rates lead to smaller intake fractions of pollutants from building materials. The study highlights the need to guide early design choices towards a good compromise between human indoor exposure and heating load, especially with the increasing emphasis on energy-efficient building design.

Chemical management and risk assessment frameworks rely on regulatory toxicity values, but these are available for only a small fraction of commercialized chemicals due to limited available data. To address this gap, the study aims to expand the coverage of chemicals for which toxicity values can be derived by determining surrogate inhalation route points of departure (PODs) and corresponding toxicity values where regulatory assessments are lacking. In vivo data from the U.S. EPA's Toxicity Value Database were curated and selected, and effect values were adjusted to chronic human equivalent benchmark concentrations (BMC_h) using the WHO/IPCS framework. Chemical-specific PODs are crucial for evaluating potential risks and toxicological impacts from chemical exposures, and the statistically derived BMCL or LOAEC/NOAEC are typically used as candidate PODs for toxicity value derivation.

The study examines the near-field exposures and health risks of organic chemicals in interior paints commonly used in Sri Lanka. The researchers developed mass balance-based and high-throughput models to predict chemical emissions during wet and dry phases and integrated these models into the USEtox model for health risk assessment. The models accurately predicted indoor air concentrations and drying time. They found that inhalation is the primary exposure pathway, and exposure is much higher for painters during application than for household members during use. The study identified chemicals of concern and recommended the use of protective equipment for painters and increasing air ventilation rates to reduce exposure for household members.

At face value, cabinetry may seem to be made of one type of wood, but its construction is much more complex. Many prefabricated cabinets are built using a combination of three or more wood composites and veneers, which typically use toxic glues containing formaldehyde, a known human carcinogen.

By comparing the material contents and construction in prefabricated cabinets, we created a spectrum that indicates the relationship between affordability and health. We typically consider the health effects during all phases of product development, but these diagrams are focused on the health effects during installation and inhabitation.

Currently, prefabricated cabinets are composed of 5%-30% healthier materials. Designers can increase this percentage by requesting manufacturers to build with NAF (no added formaldehyde) composite woods. This often comes with an increased price. Our Composite Wood Product and Spec Guidance gives a range of healthier substitutions.

The Framework Manual introduces, in a structured way, various facets of green and sustainable chemistry, with the intention to foster learning, reflection and scale up action based on a common global understanding of the concept. It features an organizing framework that unpacks various topics relevant for green and sustainable chemistry literature. The Manual is setting objectives and guiding considerations from green and sustainable chemistry, as well as an innovation and research framework are offered to stimulate stakeholder action at various levels and in different settings. Ultimately, the Manual seeks to promote innovation that unveils the full power of chemistry, and is compatible with, and supports implementation of global sustainable development goals and targets. The range of topics covered in the Manual have been identified following a review of the green and sustainable chemistry literature, the 2019 UNEP report on best practices in sustainable chemistry, and the second edition of the Global Chemicals Outlook (GCO-II). Resources permitting, the Framework Manual will be complemented by specific manuals, covering selected topics of interest to stakeholders. The Manual is structured alongside the elements of the conceptual framework “Advancing sustainability through green and sustainable chemistry” which was developed through a consultative process and is introduced below. Chapters 2, 3 and 4 address the question of: “Why” is green and sustainable chemistry needed and “What” does it aim to achieve, and in which specific innovation areas. Chapters 5, 6 and 7 focus on enabling tools and measures to advance green and sustainable chemistry (the “How”). These action-enabling elements range from promoting life cycle approaches, to strengthening research and innovation policies and programmes. An important cross-cutting topic is the need to scale up awareness raising and education initiatives at all levels that bring the green and sustainable chemistry agenda to potential actors, through formal and informal education.

This guidance document aims to give an overview of potential hazardous substances that might occur in construction products and when appearing as waste need attention during renovation and demolition activities. Focus in this guideline is on hazardous substances regulated by EU or international agreements or national legislation.

Although the present legislation restricts the use of many hazardous substances in new building products, there is a considerable concern for compounds present in old construction products, since their presence in construction and demolition waste may limit the recyclability of the material and potentially cause waste management problems. One group of substances that has recently received attention are persistent organic pollutants (POP substances) such as e.g. some brominated flame retardants.

Important characteristic of the construction and building products is the relatively long life span. Because of long lifespan the restricted substances will enter the waste stream many decades after a ban has been placed on their use and they can therefore be found in renovation or demolition waste for a long time. Many of these substances provide important functionality in a wide range of products, e.g. flame retardants.

Besides hazardous substances also degradation in composition and quality aspects (e.g. mould) of construction products needs to be considered.

This document is part of the pre-demolition overall guidance document developed in the PARADE project.
