“…If current plastic consumption patterns persist, global plastic production is projected to reach 1.6 billion tons per year by 2050 [1], consuming about 20% of the world's oil reserves [3,4]. Moreover, plastics pose significant threats to both macro and micro environments on a global scale [5], with more than half of man-made plastics entering and accumulating within our environment [6][7][8]. According to statistics, approximately 3 billion plastic bags are used for daily shopping and other activities in China.…”

The persistent increase in plastic consumption poses a formidable challenge to attaining climate objectives and mitigating plastic pollution, prompting a global movement towards “plastic reduction”. Given the large number and scale of colleges, it is crucial to analyze the potential for “plastic reduction” on campuses to integrate green and low-carbon practices. This study constructed a source–emission–grave (SEG) plastic waste evaluation framework, which chose Xi’an Shiyou University in Western China as the research object. Furthermore, a tailored plastic-reduction scheme is designed based on students’ daily consumption patterns. The evaluation effectively measures the university’s potential for reducing plastic usage and its direct environmental benefits. Results indicate that by promoting green consumption practices, there could be a potential 45% reduction in plastic usage among students in their daily routines, resulting in an annual per capita decrease of 4.4 kg of plastic consumption and utilization. The aforementioned leads to four environmental benefits, namely raw materials, savings in energy consumption, reduction in carbon emissions, and a decrease in plastic waste, resulting in a total value of CNY 45. If this program were implemented nationwide across colleges and universities, students could collectively reduce their annual plastic consumption by 162,000 tons within their daily lives while simultaneously generating direct economic benefits worth CNY 1.8 billion. These findings can serve as valuable references for other universities in devising effective initiatives to mitigate plastic consumption.

“…Consequently, PLA production can be considered (relatively) competitive with traditional plastics, because of its availability, biodegradable properties, and economic feasibility, especially as it has the potential to substitute PP, as reflected in the increasing investments in PLA production in the US and EU [21]. Examples of companies that commercially manufacture PLA are NatureWorks (Bangkok, Thailand), Natur-Tec (Circle Pines, MN, USA), and TotalEnergies and Corbion joint venture (Amsterdam, The Netherlands) [86].…”

Large-scale worldwide production of plastics requires the use of large quantities of fossil fuels, leading to a negative impact on the environment. If the production of plastic continues to increase at the current rate, the industry will account for one fifth of global oil use by 2050. Bioplastics currently represent less than one percent of total plastic produced, but they are expected to increase in the coming years, due to rising demand. The usage of bioplastics would allow the dependence on fossil fuels to be reduced and could represent an opportunity to add some interesting functionalities to the materials. Moreover, the plastics derived from bio-based resources are more carbon-neutral and their manufacture generates a lower amount of greenhouse gasses. The substitution of conventional plastic with renewable plastic will therefore promote a more sustainable economy, society, and environment. Consequently, more and more studies have been focusing on the production of interesting bio-based building blocks for bioplastics. However, a coherent review of the contribution of fermentation technology to a more sustainable plastic production is yet to be carried out. Here, we present the recent advancement in bioplastic production and describe the possible integration of bio-based monomers as renewable precursors. Representative examples of both published and commercial fermentation processes are discussed.

“…Bioplastic production is one of the most promising strategies to cope with the global fossil fuel crisis [ 1 ]; however, it currently accounts for only 1% of plastics produced annually [ 6 ]. Bioplastics, having similar functions to petroleum-based plastics, can be made from eco-friendly feedstock without depleting natural resources [ 7 ].…”

Dynamics of PHA-Accumulating Bacterial Communities Fed with Lipid-Rich Liquid Effluents from Fish-Canning Industries

The biosynthesis of polyhydroxyalkanoates (PHAs) from industrial wastes by mixed microbial cultures (MMCs) enriched in PHA-accumulating bacteria is a promising technology to replace petroleum-based plastics. However, the populations’ dynamics in the PHA-accumulating MMCs are not well known. Therefore, the main objective of this study was to address the shifts in the size and structure of the bacterial communities in two lab-scale sequencing batch reactors (SBRs) fed with fish-canning effluents and operated under non-saline (SBR-N, 0.5 g NaCl/L) or saline (SBR-S, 10 g NaCl/L) conditions, by using a combination of quantitative PCR and Illumina sequencing of bacterial 16S rRNA genes. A double growth limitation (DGL) strategy, in which nitrogen availability was limited and uncoupled to carbon addition, strongly modulated the relative abundances of the PHA-accumulating bacteria, leading to an increase in the accumulation of PHAs, independently of the saline conditions (average 9.04 wt% and 11.69 wt%, maximum yields 22.03 wt% and 26.33% SBR-N and SBR-S, respectively). On the other hand, no correlations were found among the PHAs accumulation yields and the absolute abundances of total Bacteria, which decreased through time in the SBR-N and did not present statistical differences in the SBR-S. Acinetobacter, Calothrix, Dyella, Flavobacterium, Novosphingobium, Qipengyuania, and Tsukamurella were key PHA-accumulating genera in both SBRs under the DGL strategy, which was revealed as a successful tool to obtain a PHA-enriched MMC using fish-canning effluents.
