Plastics Recycling and Hazardous Substances – Risk Cycle

Published: July 2, 2024

The complexity of plastic polymers and even more so additives has increased enormously in recent years. This makes the high-quality recycling mixed waste considerably difficult. Some have now been strictly regulated or completely banned for good reasons ('legacy additives'). Material mechanical generally utilises old plastics that still contain these substances. Consequently, products are manufactured using such recyclates contaminated with harmful We therefore recommend avoiding use intensive contact consumers until further notice. also show climate policy challenges (and chemical) industry necessitate a defossilisation ('feedstock change'). turnaround can only succeed if solely takes place future; should primarily replace virgin plastics. work used high degree homogeneity known formulation collected separately, as is already case today PET bottles. In this context, we would like to point out inconsistencies current legislation on European emissions trading system.

Effect of a Chitosan-Based Packaging Material on the Domestic Storage of “Ready-to-Cook” Meat Products: Evaluation of Biogenic Amines Production, Phthalates Migration, and In Vitro Antimicrobic Activity’s Impact on Aspergillus Niger

Separations, Journal Year: 2024, Volume and Issue: 11(6), P. 159 - 159

Published: May 21, 2024

The consumption of “ready-to-cook” foods has been experiencing rapid expansion due to modern lifestyles, and they are often sold in economical multipacks. These necessitate packaging that maintains their quality for extended periods time during home storage once the original is opened. This study evaluates a chitosan-based film derived from low- high-molecular-weight (MW) chitosan acetic acid without synthetic additives as an alternative material beef burgers. burgers were stored at 8 °C after being removed sales packaging. A commercial polyethylene (PE) designed food use, devoid polyvinylchloride (PVC) additives, served reference material. production six biogenic amines (BAs), indicative putrefactive processes, was monitored. Additionally, release four phthalates (PAEs), unintentionally present films, assessed using solid-phase microextraction coupled with gas chromatography/mass spectrometry (SPME-GC/MS). Microbiological tests conducted investigate antimicrobial efficacy against Aspergillus Niger NRR3112. results showed particularly those low MW (LMW), exhibited superior meat preservation compared PE films. Furthermore, released PAEs below legal limits demonstrated complete inhibition fungal growth. findings highlight potential viable effective option extending shelf-life maintaining products domestic storage.

Bisfenol A na indústria alimentícia. Análise comparativa entre carnes e produtos cárneos enlatados e não enlatados

PubVet, Journal Year: 2024, Volume and Issue: 18(09), P. e1655 - e1655

Bisphenol A is a chemical substance capable of producing harmful effects on human and animal health, among which reproductive, neurological, metabolic digestive alterations developmental disorders stand out. Despite these contraindications, its use widespread worldwide in high demand the industry due to resistance properties it offers. In food sector, used manufacturing packaging, specifically cans coated with epoxy resins polycarbonate packaging. Various scientific studies have been able confirm that meat products contain significant amounts it, both their canned fresh forms. This bibliographic review aims understand legal context found tolerable daily intake levels, as well analyze impact investigate main routes exposure this possible migrations bisphenol towards products. addition, alternatives are explored, including analogues. highlights large presence need for stricter regulation preserve health population. Likewise, urgency greater research find safer more sustainable concluded.
