“…In the short term, clear labeling of packaging materials, consumers' education to identify more sustainable packaging alternatives and more efficient safety and sorting systems within the waste management and recycling systems could contribute to a more sustainable use of food packaging [71,75]. Besides, sustainable recycling systems need to be cost effective in terms of the selected recycling technology, material quality of recycled products (depending on the type and conditions of secondary raw materials recollected from waste stream), availability (in terms of economy of scale), and recollection and sorting cost [28,90,91]. Facilitating recyclability has not only environmental and economic benefits, but also a social contribution, considering that dry waste sorting and selling constitute the income source for low-income workers in some countries [76].…”

Food loss and waste occur for many reasons, from crop processing to household leftovers. Even though some waste generation is unavoidable, a considerable amount is due to supply chain inefficiencies and damage during transport and handling. Packaging design and materials innovations represent real opportunities to reduce food waste within the supply chain. Besides, changes in people’s lifestyles have increased the demand for high-quality, fresh, minimally processed, and ready-to-eat food products with extended shelf-life, that need to meet strict and constantly renewed food safety regulations. In this regard, accurate monitoring of food quality and spoilage is necessary to diminish both health hazards and food waste. Thus, this work provides an overview of the most recent advances in the investigation and development of food packaging materials and design with the aim to improve food chain sustainability. Enhanced barrier and surface properties as well as active materials for food conservation are reviewed. Likewise, the function, importance, current availability, and future trends of intelligent and smart packaging systems are presented, especially considering biobased sensor development by 3D printing technology. In addition, driving factors affecting fully biobased packaging design and materials development and production are discussed, considering byproducts and waste minimization and revalorization, recyclability, biodegradability, and other possible ends-of-life and their impact on product/package system sustainability.

“…A few further studies also used models that considered learning effects, oil prices, prices for fossil-based plastic, feedstock and production costs, and price elasticity, reporting different results. This was due to an optimistic view of some variables compared to others and their complex dynamics, difficulty quantifying the influencing factors, data scarcity, and others [66]. Furthermore, efforts to identify key factors influencing market diffusion of common biopolymers by [67] the consumer and sensitivity to the consumer [68,69] are worthwhile mentioning and pursuing.…”

Bio-Based Plastics Production, Impact and End of Life: A Literature Review and Content Analysis

et al. 2022

The accumulation of plastic wastes is one of the most widely spread problems affecting the environment. The reality that plastics can be made from renewable resources and degrade naturally has prompted academics to think outside the box to develop “better for the environment” items. In this paper, a bibliometric analysis of the scholarly publications related to bio-based plastics within the last 20 years is presented. Annual progression, geographic and research area distribution, and keyword co-occurrence were all examined. Six distinct clusters emerged from keyword analysis, which were further categorized into three directions: production to marketing; impact on the environment, economy, and society; and end-of-life (EoL) options. The major focus was on how to counter the weaknesses and challenges of bio-based plastics and take opportunities using the inherent advantages of bio-based plastics. Comprehensive studies regarding the impact of bio-based plastics on the environment, economy and social sustainability are still deficient. Although there are many promising innovations in this area, most of them are at the research stage. The benefits of bio-based plastics and better EoL options can be enjoyed only after increased production.

“…The production of biobased plastic materials approached 2 million tons in 2020 and it is foreseen to rise to 7 million tons in 2026. An amount of 40% of these materials are nonbiodegradable, mainly bio-PE, bio-PP, bio-PET, and bio-PA, while the other part is biodegradable and can be treated by anaerobic digestion for the production of biogas. , To reach properties similar to those of traditional plastic polymers, biodegradable materials, such as PLA and starch and cellulose-derived polymers, must have a high crystallinity degree and additives and plasticizers are needed. These factors make their biodegradability not straightforward; studies on the decomposition of these polymers in anaerobic digestion showed that PLA and cellulose esters lead to low biogas yields and require a long time to be processed .…”

Cellulose acetate waste from eyewear industry is produced in considerable amounts, and its biodegradability is not straightforward due to the presence of plasticizers and the slow kinetics of deacetylation reactions. In this work, the chemical recycling of cellulose acetate waste coming from eyewear industry is proposed through hydrothermal treatment with the aim of acetic acid and diethyl phthalate recovery. Cellulose acetate was first characterized to determine the acetylation degree which was measured to be 2.45 and the amount of diethyl phthalate which was 30% by weight. Hydrothermal tests were performed in batch 10 mL reactors studying the influence of temperature (190−250 °C) and reaction time (10− 240 min). The products were characterized by gas chromatography− mass spectrometry and Fourier transformed IR analysis, in order to determine the acetic acid and diethyl phthalate recovery percentage. The maximum recovery of acetic acid, 90%, was obtained at 250 °C for a reaction time of 30 min; in these conditions, the diethyl phthalate extracted was about 20% by weight, which is 65% of recovery. The diethyl phthalate undergoes a hydrolysis reaction at high temperatures and long reaction times, decreasing its recovery degree. The diethyl phthalate is recovered mainly in the liquid phase extracted with ethanol and for 210 °C and 60 min and 190, 240 min it is almost pure (>97%), with a recovery efficiency of 87%. Cellulose decomposition products, mainly 5-(hydroxymethyl)furfural, were detected in the liquid products with an increase raising the reaction temperature and time. Aspen Plus simulation was performed in order to figure out the whole process including the separation of the products; a preliminary energy balance indicates that combustion of the solid residue can contribute to lower the energy required for the process, which results in 800 MJ/h for a plant capacity of 10 ton day −1 .
