Sugarcane is a lignocellulosic crop and the juice extracted from its stalks provides raw material for 86% of sugar production. Globally, sugarcane processing to obtain and/or ethanol generates more than 279 million tons solid liquid waste annually, as well by-products; namely, straws, bagasse, press mud, wastewater, ash bagasse incineration, vinasse distillation, molasses. If not properly managed, this will pose risks both environmental factors human health. Lately, valorization has gained momentum, having an important contribution fulfillment policies objectives related sustainable development circular bioeconomy. Various technologies are well-established implemented by-products processing, while other innovative still in research stage, with encouraging prospects. We propose flow present analysis physico-chemical characteristics generated wastes by-products. emphasize available possibilities valorizing each by-product, considering that they biomass resources obtaining biofuels wide range products added value, which contribute sustainability environment, agriculture, health worldwide.

Biomethane Production from Sugarcane Vinasse in a Circular Economy: Developments and Innovations

Fermentation, Год журнала: 2023, Номер 9(4), С. 349 - 349

Опубликована: Апрель 1, 2023

Sugarcane ethanol production generates about 360 billion liters of vinasse, a liquid effluent with an average chemical oxygen demand 46,000 mg/L. Vinasse still contains 11% the original energy from sugarcane juice, but this is diluted. This residue, usually discarded or applied in fertigation, suitable substrate for anaerobic digestion (AD). Although technology not yet widespread—only 3% bioethanol plants used it Brazil past, most discontinuing process—the research continues. With biomethane potential ranging 215 to 324 L methane produced by kilogram organic matter AD could improve output biorefineries. At same time, residual digestate be as agricultural amendment microalgal further stream valorization. review presents current and describes state art vinasse AD, including technological trends, through recent patent evaluation.

Farming practices reliant solely on synthetic agrochemicals face unreliability in the current era marked by unpredictable climate changes and rapid soil health deterioration. Consequently, a shift towards sustainable approaches is imperative to ensure both food security environmental quality. Molasses vinasse, abundant organic liquid by-products from sugar processing distillery industries respectively, have historically served as conditioners biofertilizers. Despite their potential, effectiveness amendments remain relatively unknown globally. In response, we conducted systematic literature review unveil benefits of molasses vinasse amendments. Our findings reveal that these consist inorganic compounds enhance aquatic ecosystem performance. These include essential plant nutrients mineral elements matter, contributing improved physico-chemical biological properties. Notably, application crop production has demonstrated superiority over chemical fertilizers, particularly when combined with other been reported significantly increase yield several crops including sugarcane ( Saccharum officinarum ), tomatoes Solanum lycopersicum soybean Glycine max maize Zea mays ) rice Oryza sativa ). Strategic utilization potential quality reducing heavy metal loads mitigating negative impacts associated fertilizers. However, it crucial note irregular disposal or misuse can result detrimental effects environment human health. To encourage global scale, establish appropriate dosages, raise awareness among farmers stakeholders regarding judicious use, develop effective methods for handling vinasse. This approach ensures cost-effective environmentally friendly amendments, fostering harmonious balance between agricutural productivity ecological well-being.

Vinasse is a toxic pollutant if it poured into the ecosystem indiscriminately; despite this, integrates components that make valuable in nutrients and water. However, its use has been questioned due to costs involved purification. This systematic review focuses on valorization of vinasse from studies performed for post-industrial use. Trends management bioproduct development were analyzed. The PRISMA statement was used as formal guide collecting analyzing 131 2018 2022. We determined biological processes are most obtain benefits vinasse, obtaining up three bioproducts. While true there predominant trend focused generation biofuels, must be noted beginning sucro-alcohol chain agricultural field. In this sense, we determine 14% treat reuse purposes, so, under Circular Economy principles, reincorporation field take advantage goodness minerals sustainable eco-efficient alternative should research accelerates consumption generated alcohol distilleries.

Scientific Reports, Год журнала: 2024, Номер 14(1)

Опубликована: Май 16, 2024

Abstract An effective strategy for enhancing fruit production continuity during extended sweet pepper season involves adopting innovative biostimulants such as potassium silicate (PS) and vinasse. Adjusting PS vinasse concentrations are crucial maintaining the balance between vegetative growth, particularly in with a shallow root system, to sustain fruiting over prolonged season. However, interaction underlying physiological mechanisms that extend under greenhouse conditions remain unclear. This study aimed investigate impact of treatments on yield biochemical constituents perennial plants cultivated conditions. For two consecutive seasons [2018/2019 2019/2020], were sprayed (0, 0.5, 1 g/l) drenched 1, 2, 3 l/m ). To estimate yield, plants, fresh dry biomass, potential some evaluated. Results revealed (0.5 coupled (3 ) generated most remarkable enhancement, terms plant total leaf area, weight both growing seasons. The implementation at 0.5 g/l demonstrated pronounced augmentation contents (chlorophyll index, nitrogen potassium), alongside improved quality, including soluble solid ascorbic acid contents, By implementing optimal combination vinasse, growers can significantly enhance biomass while fruiting, thereby maximizing superior

The Bio-Circular-Green Economy initiative adopted in Thailand encourages using sugar mill by-products for food production, benefiting both farmers and the environment. This study assesses feasibility of applying from mills distilleries into plantations irrigation, fertilization, soil conditioning. It addresses challenges sustainable waste utilization offers recommendations. reviews literature, conducts preliminary surveys, analyzes samples sugarcane fields Kanchanaburi, Thailand. findings reveal that while vinasse filter cake demonstrate promise as conditioners, their application requires careful consideration type pre-treatment processes. Vinasse, rich essential nutrients, can benefit sandy soils by improving microbial activity nutrient availability. Filter exhibits positive effects on texture, water permeability, mineral content. Treated wastewater be used ferti-irrigation. However, about one-third lack confidence its use due to concerns limited availability, high transportation costs, potential negative impacts health, agriculture, ecosystem. To enhance farmer adaptability ensure successful waste, several must addressed, including: (1) assessing financial technical value-added products, (2) overcoming regulatory barriers related industrial wastes, (3) disseminating knowledge regarding proper fertilization practices, (4) implementing long-term monitoring ecosystem health conducting sustainability assessments affirm attainment.
