The imperative to transform current energy provisions is widely acknowledged. However, scant attention has hitherto been directed toward rural municipalities and their innate resources, notably biogenic resources. In this paper, a methodological framework is developed to interconnect resources from waste, wastewater, and agricultural domains for energy utilization. This entails cataloging existing resources, delineating their potential via quantitative assessments utilizing diverse technologies, and encapsulating them in a conceptual model. The formulated models underwent iterative evaluation with engagement from diverse stakeholders. Consequently, 3 main concepts, complemented by 72 sub-concepts, were delineated, all fostering positive contributions to climate protection and providing heat supply in the rural study area. The outcomes’ replicability is underscored by the study area’s generic structure and the employed methodology. Through these inquiries, a framework for the requisite energy transition, with a pronounced emphasis on the coupling of waste, wastewater, and agriculture sectors in rural environments, is robustly analyzed.

“…This reduces greenhouse gas emissions, waste recycling and energy production from woody and herbaceous crops or biobased material transformed by food and agroindustrial processing (e.g. waste from fruit and vegetable processing) [53,58]. An interesting method that allows for using food waste, residues or by-products is to use them as raw materials or enriching additives in food processing.…”

Background. The food industry generates large amounts of food waste during production, which is often underutilized. Various sorts of food waste with different chemical composition and physicochemical properties are produced depending on the type of industry. Due to increasing public concern about waste production, environmental protection, circular economy and knowledge about the chemical composition of food waste, it is becoming a potential raw material in food production as a high nutritional by-product. Results and conclusions. The main food waste generated during beer production is brewers' spent grain (BSG), accounting for approx. 85 % of all by-products. Owing to low cost and significant protein content, it is currently used in animal feeding. However, high levels of dietary fiber, minerals and antioxi dants create an opportunity to apply BSG not only as a bioactive compound extraction material but also as a raw material in human food processing. Therefore, this literature review concerned the possibility of applying BSG in the production of various value-added food products and its impact on chemical, physi cochemical and sensory properties. The main issue related to the application of BSG in food products is decreasing product sensory scores due to changes in color, aroma and texture. However, increasing a nutritional value and health-beneficial effects could enhance attractiveness, reduce sensory barriers and increase interest in BSG-derived food products.

Sugarcane bagasse stands as one such alternative-a residue accounting for approximately a quarter of the total weight after juice extraction 60% to 80% carbohydrates (Sing et al, 2023). However, the fermentation of these carbohydrates remains underutilized, as bagasse is typically either discarded as agricultural waste or incinerated for energy in sugar and ethanol mills.…”

"Bioethanol, a renewable fuel derived from biomass feedstocks like agricultural residues and forestry waste, holds immense promise for sustainable energy production. Notably, sugar bagasse—a residual lignocellulosic material after sugarcane juice extraction—offers a valuable substrate due to its high sugar content. To harness its potential for bioethanol generation, optimizing parameters, such as temperature, pH, and fermentation duration. This study is geared towards the strategic enhancement of bioethanol synthesis from sugar bagasse, employing the Box Behnken experimental design using Aspergillus flavus as the biocatalyst. Employing rigorous statistical modeling and analysis, the investigation dissects the intricate interplay of temperature, pH, and fermentation duration on the bioethanol production kinetics. The outcomes underscore the optimal operational nexus that attains peak bioethanol yield: a thermal setpoint of 32.6°C, a pH milieu of 5.3, and a fermentation interval spanning 57.9 hours. The discerned synergy of these conditions culminates in an impressive bioethanol yield of 41.6 mg/L, manifesting a remarkable 56.9% escalation relative to the baseline conditions. This inquiry not only imparts nuanced insights into the precision-tuning of bioethanol synthesis from sugar bagasse through Aspergillus flavus but also furnishes a pivotal trajectory for the advancement of sustainable, environmentally conscious biofuel production."
