“…Food packaging is crucial for the safe delivery of food to the consumer. It has important role in reducing food waste by protecting food products from the environment that may affect food quality during storage and transport (Schmid 2013;de Léis et al 2017). Many food packaging materials such as petrochemical origin plastics, metal, paper and glass are available in the market, but the use of these materials causes waste and environmental problems (Kenneth and Betty 2007).…”

The effects of using whey powders with different demineralisation rates on the physicochemical, thermal, mechanical, and microstructural properties of gelatine-based edible films were investigated. Films were produced from film-forming solutions (FFS) containing whey powder (WP) and 50, 70 and 90% demineralised whey powder (50DWP, 70DWP, 90DWP). The addition of whey powders increased the pH and particle size values of FFS. The zeta potential decreased significantly in the WP sample and gradually reduced depending on the demineralisation rate in the DWP samples. The addition of whey powders partially increased the density of the films. WP addition reduced the hydrophobicity of the film, while the addition of DWPs did not cause any change. The addition of whey powders decreased the L* and a* values of the films while increasing the b* values. Control was the most transparent, while 70DWP and 90DWP films had higher opacity. WP films had the most uniform and smooth surface. The highest degradation temperature (269.64°C) was observed in the control sample. The weight loss of the control was 95%, whereas those of WP and DWP samples were 88-89%. WP addition reduced the tensile strength and increased the elasticity of the films.

“…For cassava, starch isolation followed the environmental loads detailed by de Léis et al. (2017). In brief, starch was modeled based on secondary data retrieved from the Ecoinvent database, consisting of “Tap water {PE}| market for tap water,” “Electricity, low voltage {PE}| market for,” “Heat, district or industrial, other than natural gas {RoW}| heat production, straw, organic, at furnace 300 kW.” In the case of sweet potato, starch extraction followed the inventory data as reported by Costa et al.…”

Starch foams are natural and biodegradable alternatives proposed as sustainable replacements to expanded polystyrene. Despite being recognized as eco‐friendly materials, environmental impacts associated with their production process remain poorly studied. Here, the cradle‐to‐gate life‐cycle assessment of four types of starch‐based foams (potato, cassava, corn, and sweet potato) reinforced with peanut skin was assessed and analyzed. Chemically modifying starch by acetylation may accelerate the degradation ratio and decrease its hydrophilicity, which is a common issue in packaging applications. Hence, two starch scenarios were evaluated, considering as‐prepared and acetylated starches. The environmental burden of starch foam production varied depending on the starch source due to the different agricultural and irrigation practices. By incorporating 10 wt% of acetylated starch, the environmental impact drastically increased in most categories. Additionally, the sensitivity analysis carried out with different peanut skin contents showed a limited effect under 0–30 wt% of peanut skin, suggesting that peanut production exhibits a similar environmental burden to most starches.

“…In these situations, the coating figured only in supporting roles. Some reports of successful experience applying LCA to assess the environmental performance of installed industrial processes or those displaying implementation potential in Brazil have been published more recently [27][28][29][30][31][32][33][34][35]. However, in all these cases, the technique was employed in the scope restricted to the production cycle (from cradle-to-gate) to identify environmental arrangement bottlenecks and propose improvement actions based on engineering conduct and management practices.…”

Coalescents are compounds with a high potential for generating tropospheric ozone, which causes adverse effects on humans and their surroundings. This study designed a coalescent for decorative paints that reached technical levels equivalent to those obtained by StC, a product on the market, but with better environmental and economic performance. The strategy adopted in creating the green coalescent (GrC) improved film formation and reduced the product’s atmospheric emission rate. Regarding the environmental performance, GrC outperformed StC in terms of water consumption, global warming potential, and human toxicity by 30%, 35%, and 91%, but had a high smog formation potential even with a reduced loss to the air. The redesign of the molecule gave rise to AGrC, which achieved a more homogeneous environmental performance. The results of an economic analysis indicated that the procedures adopted to reduce environmental impacts could also make the coalescent more competitive if the lowest market prices were practiced. On the other hand, if the products are sold at high prices, the paint industry tends to privilege the economic dimension and disregard environmental performance for decision purposes. This research succeeded in reconciling technical functions and aspects related to sustainability to design more competitive products in the Brazilian market.
