Advances in research and development of bioplastic for food packaging

Nowadays the heightened awareness of the critical trend in resource depletion impels to improve the eco − sustainability of any productive process. The research presented in this paper aims to quantify the environmental impact of the emerging productive process of edible flowers, focusing on two model species, i.e., Begonia x semperflorens − cultorum hort and Viola cornuta L., and two types of product, i.e., flowering potted plants sold in plastic vases and packaged flowers ready to be consumed. The study was carried out in an Italian nursery located in Tuscany, interviewing the owners in order to complete the Life Cycle Inventory, assessing the value of the impact categories, and using the “cradle to gate” approach. The information about the production of flowering potted plants and packaged flowers were inserted in a database and elaborated by the appropriate software. The results of the Life Cycle Assessment (LCA) analysis referred to 1 g of fresh edible flowers and were expressed in four impact categories. Global Warming Potential (GWP) values ranged from 24.94 to 31.25 g CO2 eq/g flowers, Acidification Potential (AP) ranged from 8.169E − 02 to 1.249E − 01 g SO2 eq/g flowers, Eutrophication Potential (EP) ranged from 3.961E − 02 to 5.284E − 02 g PO43 − eq/g flowers, and Photochemical Ozone Creation Potential (POCP) ranged from 8.998E − 03 to 1.134E − 02 g C2H4 eq/g flowers. Begonias showed lower emissions than violas in the GWP and POCP indexes, whereas violas showed lower values in the AP and EP impact categories. The most impactful phase was the propagation, accounting on average for 42% of the total emissions. Overall, the findings highlighted a higher environmental load for the production of both begonias and violas packaged flowers, especially if in small containers, rather than as potted plants, with an emission percentage increase from 8% to 17% among the impact categories.

“…Alternative sources for conventional plastics made from raw materials based on fossil fuels are bioplastics, which are bioplastics, and biodegradable plastics, made wholly or partly from renewable materials derived from biomass [44][45]. Raw materials commonly used to produce these renewable feedstocks for the production of plastics include corn stalks, sugar cane stalks and cellulose, as well as increasingly diverse oils and fats from renewable sources Biodegradable plastics are plastics with innovative molecular structures that can be decomposed by bacteria at the end of their life under certain environmental conditions.…”

Perils of plastic waste (PW) from polymers (ex: Polyethylene Terephthalate (PET), high-density polyethylene (HDPE), lowdensity polyethylene (LDPE), polyvinyl chloride (PVC), nylon, polystyrene (PS), etc.) , the mechanism of its spread in general and all of these types that are included in our daily life system as a product expelled continuously and/or frequently are 21 st century crisis as reported from United Nations in 2019, and especially after the outbreak of the COVID-19 pandemic. PW is a very serious issue that has negative and harmful effects on the ecosystem, beside; health and the economy through direct proportionality with the rate of increase in the state population, moreover, weak environmental awareness and Energy International Administration (EIA) towards this dangerous issue. The aim of the current survey study is to shed light on the importance of plastics in our daily life needs for food packaging, single-use personal protective equipment's, laboratory tests, etc... PW problems by knowing the chemical composition, components, uses, and harms, as well as knowing the possibility of benefiting from these wastes within the solid waste management system (MSW / Municipal). By providing some suggestions that helps reduce the harm of this waste either recycling or disposal. This study will also include approximate theoretical equations to calculate the percentage of PW in particular at Maysan governorate, Iraq; because we haven't any physical mechanism at the operational level that deals with waste sorting, especially PW; as these statistics generally depend on the official information published by the competent authority about the total amount of waste presented at the governorate level.

Petrochemical based plastics have been widely used as packaging materials, as they have good barrier properties, stiffness, tensile strength & tear strength. Although in great demand plastics have many disadvantages like very low water vapour transmission rate, non- biodegradability etc. which further causes environmental pollution. Keeping in mind about the pollution and harm caused to the nature, newer concepts about the use of bio-plastics came into force. Bio-plastics are produced from the biological sources such as potato, potato peels, corn, sugarcane, wheat, rice, banana peels etc. These plastics are environment friendly & biodegradable, and are safer option than the petroleum-based plastics. These biodegradable plastics break down into carbon dioxide, water & inorganic compounds and degrade completely. The time-line, sources and other important details about the bio-plastics have been presented in this review paper.
