Safer Consumer Products (SCP) has compiled a list of alternatives to PFASs in carpets and rugs to assist manufacturers looking for substitutes. The alternatives have been grouped into two categories: non-chemical and chemical alternatives. Products and manufacturers are listed but they are not endorsed by SCP and the safety of the alternatives has not been assessed.

In recent years the majority of glues used in wood composite boards have been urea-formaldehyde (UF) and phenol-formaldehyde (PF) resins.  However, these products may cause human health issues due to off-gassing of formaldehyde, which is recognised by the World Health Organisation as a potential human carcinogen, which can also cause irritation of the eyes, nose, lungs and throat.

However, development of no-added formaldehyde (NAF) glues and resins is a growing area, which not only provide a safer indoor environment, but also can reduce the use of fossil-based feedstocks, and are biodegradable.  This case study looks at how NAF adhesives based on abundant soybean feedstocks, taking inspiration from processes in nature can address this chemical hotspot, and how the product was intially researched by Dr. Kaichang Li of Oregon State university, and came to market through collaborations with Columbia Forest Products and Hercules.  Soy-based adhesives can now demonstrate cost-competitiveness with UF adhesives, and are being widely procured for buildings seeking to achieve complaince with air quality regulations and higher building rating scores.

Chemicals are essential for the well-being, high living standards and comfort of modern society. They are used in many sectors, including health, energy, mobility and housing.

However, most chemicals have hazardous properties which can harm the environment and human health.

The EU already has sophisticated chemicals laws in place, but global chemicals production is expected to double by 2030. The already widespread use of chemicals will also increase, including in consumer products.

The European Commission published a chemicals strategy for sustainability on 14 October 2020. It is part of the EU’s zero pollution ambition, which is a key commitment of the European Green Deal.

This report provides an overview of the current status and conditions of the Circular Economy in the electronics value chain in the Latin America and the Caribbean (LAC) region, identifies key areas of concern, provides appropriate recommendations, and proposes priority actions to improve circularity of the sector. The recommendations and roadmap focus on the individual life cycle stages of the electronics value chain, as well as on aspects that cut across the value chain. The transition towards a more circular electronics sector in Latin America and the Caribbean (LAC) would require a holistic and coordinated approach to progress toward a more circular electronics value chain in the CEE region.

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.

Strengthening legal efforts in Nigeria is crucial for successful implementation of Extended Producer Responsibility (EPR) systems. By having the National Environmental Standards and Regulations Enforcement Agency of Nigeria (NESREA) having the enforcing EPR laws create a more sustainable and accountable e-waste sector.

Developing and updating EPR legistlations helps clarify the different responsibilities and enforce producers to comply with their obligations and responsibility. However, effective EPR implementation will require further law enforcement measures.
The case study outlines two achievements of the "Circular Economy Approaches for The Electronics Sector In Nigeria" project towards establishing a stronger legal system in Nigeria:

• The development and gazette of the EPR Guidance document in 2020: the guidance defines the roles and responsibilities of the key public and private stakeholders, the product categories to be covered by the EPR scheme, and the collection and recycling targets.
• The amendment of the National Environmental (Electrical and Electronic Sector) Regulations in 2022: which legally requires EPR subscriptions and prohibits suboptimal treatment of e-waste.

The study concludes with a summary of key lessons and next steps, emphasizing the importance of enforcing EPR laws, engaging stakeholders, raising public awareness, and collaborating with regional and international partners.
