New possible ways of plastics manufacture and waste treatment are being searched when trying to tackle the problems related to the growth of waste quantities and decline in non-renewable resources. Presently, the most promising and effective way to solve the mentioned problems is production of bioplastics, but its way to recognition is very slow. One of the barriers is the absence of clear and united opinion throughout the EU Arising new discussions about biodegradable and biobased plastics will allow responsible authorities to update and adapt the legal law, which now almost does not include any reglement on bioplastics production and usage. The other issues of bioplastics are social aspects as this material can be made of primal food sources like crops, and the ecological ones because of their unknown effects on human health and the environment. Nevertheless, the main problem remains the same -the price of petro-plastics is still lower than that of bioplastics. Despite this, the biggest companies of the world are starting an initiative to manufacture this new kind of plastics and to widen the range of bioplastics usage in packaging. Considering today's situation and tendencies, at the end of this paper the recommendations for the improvement and speeding up of the processes related to bioplastics manufacture, usage and its waste management in Europe and Lithuania are presented.
In Europe post-consumer beverage carton packages are treated in three ways: dumped in a landfill, incinerated for energy recovery, and recycled. In recent years new technologies for beverage carton recycling have been developed and tested. At the same time in Europe the collection of second-hand raw materials is becoming more efficient. In order to facilitate and justify the decision-making process, different possibilities of poly-aluminium handling were analysed. For this reason, the objective of this study was to compare carbon footprints in the whole life cycle of selected technologies and to provide decision-making with data for beverage carton recycling. The paper is based on some of the results of the project 'Sustainable Production through Innovations in small- and medium-sized enterprises (SPIN)'. The SPIN project is providing small- and medium-sized enterprises with a whole set of instruments that put entrepreneurs in a position to innovate their production processes and products leading to improved business and public benefits.
The current food packaging model in most cases is a linear material flow model and is far from the sustainable alternative – circular economy – approach where materials are recycled and recovered at the end of each service life. High concern is rising on packaging waste and especially plastic packaging and negative environmental impact. A number of factors, including policy and legislative changes, rising concerns on food and packaging waste, environmental contamination, and world demand for food and energy resources, undoubtedly make an impact on development of biodegradable and compostable packaging made from renewable environment friendly resources and a sustainable waste management opportunity at the end of product life. Food packaging industry already has options of compostable packaging that meets biodegradation and composting standards and does not impact environmental contamination, but a variety of existing bio-labels such as biobased, biodegradable, and compostable appear misleading for consumers, and terms biodegradable and compostable are often used as synonyms, although they are not the same.
Paper and plastic are the main materials used in food packaging. In the context of climate change, the importance of tree conservation and the mitigation of the negative environmental impacts caused by fossil consumption and deforestation is greater than ever before. This article reviews the potential of plant-origin feedstock from the Baltic Sea region for use in non-wood-fibre and bio-origin plastic food packaging production. It also presents a systematised literature review of the environmental impacts and applications of tree-free paper, plant-origin plastics, and natural-fibre-reinforced bio-composites in fully green food packaging. The results reveal that beneficial environmental impacts are achieved if waste or by-products are used as feedstock. While the production volumes of alternative materials in Europe are small (0.25% of paper is made of materials other than wood, and the share of bio-plastic is 0.9%), we found a large demand and potential for growth. The biggest volumes of natural fibre feedstock in Baltic Sea region countries are generated from wheat. Wheat straw, which is a by-product, has a production volume of 68.71 million tons and is potentially a significant non-wood-paper food packaging source. Agricultural waste generated from sugar beet, maize, potato, and wheat is an environmentally beneficial by-product that could be used for bio-plastic food packaging production.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
