The use of food waste as a rearing substrate to grow insects is an ecofriendly and sustainable alternative disposal. In the present research, Hermetia illucens prepupae were reared with standard diet, different waste-based diets based on vegetables, fruits, meat, mixed one, where previous three components equally. demineralization deproteination allowed for obtainment chitin that was then deacetylated produce chitosan. Also, bleaching chitosan attempted further purification. yield reactions investigated, infrared spectra obtained materials analyzed obtain information quantity acetylation degree trend function diet. possibility slightly modulate both biopolymers thanks specific diet enlightened. Interestingly, resulted in highest fraction having degree, lowest degree.

Beyond the Bloom: Invasive Seaweed Sargassum spp. as a Catalyst for Sustainable Agriculture and Blue Economy—A Multifaceted Approach to Biodegradable Films, Biostimulants, and Carbon Mitigation

Sustainability, Год журнала: 2025, Номер 17(8), С. 3498 - 3498

Опубликована: Апрель 14, 2025

The Anthropocene has ushered in unprecedented environmental challenges, with invasive seaweed blooms emerging as a critical yet understudied facet of climate change. These blooms, driven by nutrient runoff and oceanic alterations, disrupt ecosystems, threaten biodiversity, impose economic public health burdens on coastal communities. However, seaweeds also present an opportunity sustainable resource. This study explores the valorization Sargassum spp. for agricultural applications, focusing development biodegradable bioplastics biostimulants. Field trials demonstrated effectiveness Marine Symbiotic® Sargassum-derived biostimulant distinct contexts. In Dominican Republic, pepper crops showed significant improvements, including 33.26% increase fruit weight, 21.94% rise set percentage, 45% higher yield under high-stress conditions, 48.42% reduction rejection compared to control. Colombia, across four leafy green varieties revealed biomass increases up 360%, 50% synthetic input dependency, enhanced crop coloration, improving marketability. Additionally, Sargassum-based biofilms exhibited favorable mechanical properties biodegradability, offering alternative conventional plastics. Carbon credit quantification that valorizing could prevent 89,670 tons CO2-equivalent emissions annually using just one Littoral Collection Module® harvesting system, while application carbon sequestration crops. findings underscore potential address multiple from reducing plastic pollution GHG enhancing resilience, thereby contributing Blue Economy aligning global sustainability goals.

Active Ingredients and Carriers in Nutritional Eco-Cosmetics

Compounds, Год журнала: 2023, Номер 3(1), С. 122 - 141

Опубликована: Янв. 20, 2023

Beauty and personal care became a significant part of the global economy for two reasons: (1) The elderly growing in population (2) desire women men to appear younger more attractive. Thus, both young old people are looking revolutionary nutritional eco-cosmetics (combined use cosmeceuticals nutraceuticals) manufactured by natural active ingredients, using biopolymers as substrates, made innovative sustainable technologies. Consequently, market cosmetics diet supplements is continually together with request including bio-peptides biological macromolecules such chitin lignin. Therefore, consumers industry need recover ingredients carriers (vehicles), naturally derived supported advanced methods controlling their effectiveness safeness on skin mucous membrane layers. selected bio-ingredients, hyaluronic acid bio-mimetic peptides, obtained advanced, bio nanotechnologies, will be interest develop smart cosmeceutical nutraceutical formulations. Innovation considered key business strategy drive economic growth. For trying reduce waste produce sustainable, biodegradable products, realization new non-woven tissues, used making nutraceuticals was considered. Both have been from food loss pollution. This review report brief description functions, also focus discuss some clarify supposed mechanism action, carriers, well activity beauty products.

Ilmenite-Grafted Graphene Oxide as an Antimicrobial Coating for Fruit Peels

ACS Omega, Год журнала: 2024, Номер 9(24), С. 26568 - 26581

Опубликована: Июнь 7, 2024

Postharvest loss is a significant global challenge that needs to be urgently addressed sustain food systems. This study describes simple microwave-assisted green synthesis method in developing nanohybrid material combining natural ilmenite (FeTiO3) and graphene oxide (GO) as promising antimicrobial fruit peel coating reduce postharvest loss. The was calcined an inert environment mixed with GO microwave reactor obtain the nanohybrid. then incorporated into alginate biopolymer form coating. Microscopic images revealed successful grafting of FeTiO3 nanoparticles onto sheets. Spectroscopic measurements Raman, X-ray photoemission, infrared provided insights interactions between two matrices. optical band gap calculated from Tauc's relation using UV–vis data showed reduction hybrid compared ilmenite. activity assessed Escherichia coli, which substantial decrease colony counts. Bananas coated doubling shelf life uncoated fruits. Consistent this, electronic nose (E-nose) freshness indicator tests less deterioration physicochemical properties bananas. Overall, results show applications for ilmenite-grafted capable minimizing spoilage due microbial activity.

Techno-Economic Assessment of Chitin Nanofibrils Isolated from Fungi for a Pilot-Scale Biorefinery

ACS Sustainable Resource Management, Год журнала: 2023, Номер 1(1), С. 42 - 53

Опубликована: Дек. 7, 2023

In times when transitioning from a linear carbon-intensive economy into sustainable circular is an urgent need, bio-based nanoparticles such as nanochitins are attracting increasing interest for value-added products. Fungal chitin nanofibril (ChNF) isolation show reduced CO2 footprint over crustacean shell-derived nanochitin, which requires harsh chemical treatments. However, the viability and practical implementation of ChNFs fungi may depend on manufacturing costs. Accordingly, here we assess economic feasibility pilot-scale fungi-derived ChNF comprising nanofibrils with covalently bonded β-glucans. Required capital investment, production costs, minimum product selling prices, payback periods obtained considering refinery plant treating 3000 kg fresh mushroom daily located in Bilbao, north Spain. The proposed business model offers clear signals technical, economic, commercial pilot industrial format, under relatively conservative technical assumptions. particular, total investment biorefinery estimated at ∼1.10 M€ ChNFs, where working ∼380 K€ indicates good short-term financial health company. A period 11.3 years price 212 €·kg–1 year 2024 obtained, can be lowered to 106 scenario extraction yield doubled. This value remains below nanocelluloses leading manufacturers, making competitive alternative develop novel materials addressing challenges renewability, environmental sustainability, functional properties. ease minimal use chemicals significant advantage, although low noteworthy drawback profit after taxes. sensitivity analysis conducted by five scenarios that occur upon operation. These results highlight bright future fungal nanochitin meet market demands materials, especially applications energy storage biomedicine, high prices affordable. As nanomaterials gaining momentum, techno-economic assessment shown provides cues society based bioeconomy.
