This study analyzes 163 multilayer films from commercial food packaging available on the European market to quantify structural diversity and assess implications for recyclability. Forty-two distinct multilayer configurations and twenty-seven polymer combinations were identified, with no systematic relationship to food category, film thickness, or functional requirements. Functionally similar packages frequently relied on materially incompatible or over-engineered polymer combinations, revealing a fragmented and non-standardized packaging landscape. Although all analyzed structures comply with current European food-contact regulations (EC 1935/2004 and EU 10/2011), their diversity and incompatibility hinder mechanical and chemical recycling, challenging the objectives of the forthcoming Packaging and Packaging Waste Regulation (PPWR). Overall, the results provide quantitative, market-level evidence of structural redundancy and demonstrate how fragmented design practices undermine design-for-recycling principles and the implementation of circular economy strategies in food packaging. 2026-05-25T00:00:00Z https://hdl.handle.net/10259/11728 Dataset of the project “Use of by-products from blackberry and blueberry: charaterization, effect on health and development of safer and healthier meat products (FUNCBERRY)” Melero Gil, Beatriz; Ortega Heras, Miriam; Rovira Carballido, Jordi; Muñiz Rodríguez, Pilar; Rivero Pérez, Maria Dolores; Cavia Saiz, Mónica; Gerardi, Gisela; Gómez Bastida, Inmaculada The data set contained the raw data of the project “Use of by-products from blackberry and blueberry: charaterization, effect on health and development of safer and healthier meat products” (FUNCBERRY). 2026-05-25T00:00:00Z https://hdl.handle.net/10259/11708 Dataset of the work “Physical-Chemical and Microbiological Characterisation of Blueberry By-products (Vaccinium myrtillus, L.) as Potential Food Ingredients” Ortega Heras, Miriam; González San José, Mª Luisa; Hortigüela Delgado, Ruth; Fernández Varona, Ángela; Rodríguez, Verónica; Melero Gil, Beatriz The dataset contained the raw data from the study entitled 'Physical-chemical and microbiological characterisation of three powdered products obtained from blueberry pomace: skins and seeds'. The analysed parameters included proximate composition, mineral content, total phenolic content, total anthocyanin content, antioxidant activity (ABTS), and individual anthocyanins and phenolic compounds. The microorganisms studied were aerobic mesophilic bacteria, Enterobacteriaceae, lactic acid bacteria, Bacillus spp. and Clostridium spp. The data also included the results of a heat treatment at 90 °C for 30, 60, 90 and 120 minutes. 2026-05-25T00:00:00Z
