Plastic Containers

The Japanese government developed a strategy for plastics and laid out ambitious targets including the reduction of 25% for single-use plastic waste and the reuse/recycling of 60% for plastic containers and packaging by 2030. However, the current usage situation of single-use plastics including containers and packaging, which should be a basis of the strategy, is unclear. Here, we identify the nationwide material flow of plastics in Japan based on input–output tables. Of the domestic plastic demand of 8.4 Mt in 2015, 1.6 and 2.5 Mt were estimated to be for containers and packaging comprising household and industry inflows, respectively, through the purchase/procurement of products, services, and raw materials. Considering the current amount of recycling collected from households (1.0 Mt) and industries (0.3 to 0.4 Mt), the reuse/recycling target has already been achieved if the goal is limited to household container and packaging waste, as is the focus of Japan’s recycling law. Conversely, the results indicate that it will be extremely difficult to reach the target collectively with industries. Therefore, it is essential that efforts be made throughout the entire supply chain. Food containers and packaging that flowed into the food-processing and food service sectors accounted for 15% of the inflow of containers and packaging into industries. Thus, the key to achieving the reuse/recycling target will comprise the collection of plastic food packaging from not only households but also the food industry. Furthermore, the collection of flexible plastic films used between industry sectors will put the target within reach.

A biopolymer coating for plastic films was formulated based on whey protein, and its potential to replace current synthetic oxygen barrier layers used in food packaging such as ethylene vinyl alcohol copolymers (EVOH) was tested. The whey-coating application was performed at semi-industrial scale. High barrier to oxygen with transmission rate down to ranges of 1 cm3(STP) m−2d−1bar−1at and 50% relative humidity (r.h.) but interesting humidity barrier down to ranges of 3 g m−2d−1(both normalized to 100 μm thickness) were reached, outperforming most existing biopolymers. Coated films were validated for storing various food products showing that the shelf life and sensory attributes were maintained similar to reference packaging films while complying with food safety regulations. The developed whey coating could be enzymatically removed within 2 hours and is therefore compatible with plastic recycling operations to allow multilayer films to become recyclable by separating the other combined layers. A life cycle assessment was performed showing a significant reduction in the environmental impact of the packaging thanks in particular to the possibility of recycling materials as opposed to incinerating those containing EVOH or polyamide (PA), but due to the use of biosourced raw materials.

There is global recognition that waste plastic is a ubiquitous pollutant in the built and natural environments. A component of plastic litter and debris is single-use, expanded polystyrene (EPS) food service ware. Reducing the consumption of EPS food service ware is challenging because reuse is not feasible, recycling is not economically viable, and composting is not possible. In the absence of national action to reduce EPS in the USA, local governments have taken the lead on enacting ordinances to eliminate or reduce EPS food service ware. This paper examined the variety of policy instruments that can or have been used by local governments in the USA to reduce EPS food service ware. Because of the inabilities to reuse, recycle, and/or compost EPS, the most frequently used policy instrument has been a ban. As of December 2019, there were 249 local bans in the USA covering 12.85% of the nation’s population: of these bans, 9.6% were partial bans restricting distribution only on government and public property, 65.9% were narrow bans that ban distribution by restaurants and food providers, 8.8% were full bans that include the narrow ban and also ban using EPS food packaging by grocery stores, and 15.7% adopted an expanded ban that includes the full ban and also baned other single-use plastic food ware related items including the selling or distributing of EPS coolers and single-use plastic utensils, straws, stirrers, lids, cups, plates, and containers.

Durian (Durio zibethinus) and cempedak (Artocarpus integer) peels waste are not used by the society. The research aim is to extract pectin from durian and cempedak peels and to formulate the pectin into edible films for food packaging. The research stages were first pre-treatment of durian and cempedak peels, pectin extraction, pectin drying, and  pectin application as edible films with concentration of 0%, 5%, and 15%. Based on this research it was concluded that pectin can be extracted from durian and cempedak peels with yield result of 27.97 % and 55.58 %, respectively. Edible film obtained has  similar characteristics between raw materials cempedak and durian peels. The higher concentration of cempedak peel  pectin increased the thickness, but decreased the tensile strength and elongation at a concentration of 15%. While in edible films from durian peel pectin, the higher concentration of pectin decreased the thickness of edible film on pectin concentration of 15%, lowered tensile strength and raised the edible film elongation.Keywords: waste, durian, cempedak, pectin extraction, edible film

The COVID-19 pandemic has set new challenges for the HoReCa industry. Lockdowns have coincided with and strongly impacted the industrial transformation processes that have been taking place for a decade. Among the most important HoReCa transition processes are those related to the rapid growth of the delivery-food market and ordering meals via internet platforms. The new delivery-food market requires not only the development of specific distribution channels, but also the introduction of appropriate, very specific food packaging. Food packaging and its functionality are defined by the administrative requirements and standards applicable to materials that have contact with food and principally through the prism of the ecological disaster caused by enormous amounts of plastic waste, mainly attributed to the food packaging. To meet environmental and administrative requirements, new technologies to produce food packaging materials are emerging, ensuring product functionality, low environmental impact, biodegradability, and potential for composting of the final product. However, predominantly, the obtained product should keep the nutritional value of food and protect it against changes in color or shape. Current social transformation has a significant impact on the food packaging sector, on one hand creating a new lifestyle for society all over the world, and on the other, a growing awareness of the negative impact of humans on the environment and increasing responsibility for the planet. The COVID-19 pandemic has highlighted the need to develop a circular economy based on the paradigm of shortening distribution channels, using local raw materials, limiting the consumption of raw materials, energy, water, and above all, minimizing waste production throughout the life cycle of products, all of which are in line with the idea of low-carbon development.

"The recovery of agriculture waste is one of the challenges of 2030 Agenda. Food and Agriculture Organization states that 30 % of the world’s agricultural land is used to produce food that is later lost or wasted, and the global carbon footprint corresponds to 7% of total greenhouse gases emissions. Alternatively, natural fibers contained in food and agricultural waste could be a valuable feedstock to reinforce composite biopolymers contributing to increase mechanical properties. In addition, the use of biopolymers matrix could contribute significantly to reduce the environmental footprint of the biobased compounds. Based on these premises, a regional project in Emilia-Romagna, aims to enhance agricultural waste to produce food packaging materials which in turn would contribute to the reduction of green raw materials used. This article reviews the state of art of composite biopolymers added with fillers extracted by food and agricultural waste, analyzing the literature published on scientific databases such as Scopus. The characteristics, advantages and drawbacks of each innovative sustainable material will be studied, trying to compare their various properties. The results of the work could guide companies in the choice of eco-sustainable packaging and lay the foundations for the development of the mentioned regional project."

This study assessed employment intensity of growth (EIG) in the agriculture, industry and service sectors in Nigeria from 1991 to 2019 within the context of Okun’s theory/law. Data from the 2020 World Development Indicators were employed for analysis, using elasticity procedure after decomposing the scope into different periods and regimes. The findings showed negative EIG in the agriculture and industrial sectors while the service sector returned positive EIG. Therefore, government should invest significantly in the service sector while the agricultural sector should be mechanized to boost output and supply of raw materials to industries to enhance employment generation.

The food packaging sector generates large volumes of plastic waste due to the high demand for packaged products with a short shelf-life. Biopolymers such as starch-based materials are a promising alternative to non-renewable resins, offering a sustainable and environmentally friendly food packaging alternative for single-use products. This article provides a chronology of the development of starch-based materials for food packaging. Particular emphasis is placed on the challenges faced in processing these materials using conventional processing techniques for thermoplastics and other emerging techniques such as electrospinning and 3D printing. The improvement of the performance of starch-based materials by blending with other biopolymers, use of micro- and nano-sized reinforcements, and chemical modification of starch is discussed. Finally, an overview of recent developments of these materials in smart food packaging is given.

Environmental threats are triggered by the overconsumption of raw materials. It is therefore necessary to move towards a society that both reduces extraction and keeps the majority of the extracted raw materials in the socio-economic system. Circular economy is a key strategy to reach these goals. To implement it effectively, it is necessary to understand and monitor material flows and to define hotspots, i.e. materials that need to be tackled with the highest priority. This paper is aimed at determining how to increase circularity in the Swiss economy by means of a Material Flow Analysis coupled with a simplified Life Cycle Assessment. After having characterized material flows, we analyzed two types of hotspots: i) Raw materials consumed and/or disposed at high level, and ii) Raw materials whose extraction and production generates high environmental impacts. The Material Flow Analysis shows that each year 119 Mt of raw materials enter the Swiss economy. Therefrom, 15 Mt are derived from recycled waste inside the country; 67 Mt leave the system yearly; 27 Mt towards disposal. Out of the disposed materials, 56% are recycled and re-enter the socio-economic system as secondary materials. Looking at hotspots; concrete, asphalt, gravel and sand are among materials that are consumed and disposed at high level. Yet, looking at greenhouse gas emissions generated during extraction and production, metals - including the ones in electrical and electronic equipment - as well as textiles are among the categories that carry the biggest burden on the environment per unit of material.

Abstract In Kenya, agriculture is an important economic activity, which implies that a significant amount of bio-waste is generated. This is on one hand a waste management problem, but on the other hand, it is an opportunity for creating a sustainable bioeconomy. Therefore, this study investigates the potential recovery of bioresources from Kenyan bio-waste. The study first quantifies occurrence, current usage and disposal of three selected biomass types, being banana, potato and coconut waste. Next, material flow analysis (MFA) is used to systematically track the mass flow of these wastes. Finally, the potential of biomolecules, biomaterials and bioenergy from the waste streams is evaluated. The study revealed that 6007, 426 and 49.5 kt of banana, potato and coconut biomass is wasted. All these wastes can be biorefined, offering potential towards recovery of; flavonoids (88.3 kt), starch (377 kt), cellulose (2000.7 kt) and biogas (1757.0 GWh), being the total potential of the main bioresources from the three waste streams. The study therefore, concluded that, with proper waste collection, sorting and valorisation, there is a huge potential for bioeconomy in Kenya, at the same time reducing waste management problems.
