Special Issue Information

Dear Colleagues,

Along with the advancement of global communities, we must address two critical issues: increasingly depleting fossil resources and environmental concerns (e.g., air pollution and greenhouse effects associated with the consumption of fuels). Consequently, environmentally friendly alternatives to energy derived from fossil fuels have been considered to provide a sustainable energy supply to global societies. Biomass, the oldest source of energy after the sun, is the largest renewable energy source because of its unlimited supply.

The term “biomass resources”, sometimes referred to as bio renewable resources, are all forms of organic materials, including both living and waste plant matter as well as animal matter and animal waste products. As a result, bioenergy (the energy generated from biomass resources) is of increasing interest as a renewable, environmentally friendly alternative to energy derived from fossil fuels. Biomass can be converted to solid, liquid, or gaseous biofuels via a variety of processes; however, many problems remain in the maintenance and development of biomass-to-energy utilization. Considering the global importance of efficient biomass resource utilization, the goal of this Special Issue of Sustainability is to advance and disseminate knowledge in all areas related to biomass, biological waste treatment, bioenergy, biotransformation, and bioresource systems analysis, as well as technologies associated with conversion or production. We also invite the submission of articles relating to the efficient utilization of biomass resources as livestock feeds. The scope of this Special Issue is not limited; articles relevant to the utilization of biomass resources in any form are welcome. Therefore, we would like to cordially invite you to submit your relevant papers to our journal’s forthcoming Special Issue.

Co-Development of a Tool to Aid the Assessment of Biomass Potential for Sustainable Resource Utilization: An Exploratory Study with Danish and Swedish Municipalities

In the future, there will be an increased demand for biomass to replace energy and products of fossil origin with renewable alternatives. Such a transition requires action at both the national and local level. Municipalities as key actors need tools to increase the utilization of biomass. One such tool is a means to assess biomass’ potential for use. Consequently, this study investigated how a tool to aid the “assessment of biomass potential” (ABP) could support municipalities in Sweden and Denmark to increase biomass utilization. Ten workshops were organized to gain insights into how ABP could be adopted in municipalities. A blueprint of an ABP was developed to aid discussions around four themes: (1) how should the ABP be adopted, (2) which parameters to include, (3) which departments should be involved, and (4) how complex should it be. Many workshop participants saw the biggest benefit of an ABP would be in supporting the municipalities’ climate action plans and helping build up the goals and scopes related to biomass utilization. However, for successful adoption of the ABP, many departments need to be involved, which would require building up staff competences. This study shows that ABP could support the increased utilization of biomass. Full article

Valorization of Coffee Silverskin through Subcritical Water Extraction: An Optimization Based on T-CQA Using Response Surface Methodology

Coffee silverskin (CS) is the only byproduct of the roasting process for coffee beans and is rich in phenolic compounds with various bioactivities. This study proposes a valorization option for bioactive compounds (T-CQA) based on a subcritical water extraction (SWE) technique, which is known for its high efficiency and feasibility for use on an industrial scale. The use of water as a sole solvent requires a minimum number of cleaning steps and renders the extract safe for further applications, such as in either the cosmetic or food industry. Response surface methodology with a Box–Behnken design is effectively used to optimize and explain the individual and interactive process variables (i.e., extraction temperature, extraction time, and solid–liquid ratio) on the T-CQA content obtained from coffee silverskin by the SWE technique. The final model exhibits a precise prediction of the experimental data obtained for the maximum T-CQA content. Under the optimum conditions, the CS extract is found to contain a higher content of T-CQA and TPC than that reported previously. For antioxidant activity, up to 26.12 ± 3.27 mg Trolox equivalent/g CS is obtained. Full article

Given the increasing demands for the quality and safety of animal-derived foods and the strict regulations on the use of antibiotics in animal feed, the use of functional feed additives has attracted increasing research and development. Jujube fruit is an energy-rich food with antioxidant, antibacterial, and antidiarrheal properties. With the expanding areas of cultivation to jujube trees and the intensive processing of jujube in Asia, especially in China, a large number of jujube by-products are produced. These by-products are used widely in animal feed for pigs, chicken, cattle, goats, and fish, as they improve growth performance, promote digestive tract health, and enhance the quality of animal products. This article reviews the nutritional components and benefits of jujube by-products and their potential incorporation in animal feed. The aim of this review is to introduce jujube by-products as a novel supplement or partial dietary replacement in the animal feed industry. Full article

A lick block (LB) is a solidified mixture of molasses, urea, minerals, filler, coagulant and binder that is supplemented to livestock mainly in relatively extensive rearing systems. It provides nutrients, such as soluble sugars, proteins, minerals and vitamins to balance dietary intake and can improve rumen fermentation and facilitate digestion and absorption of nutrients. These supplements improve livestock production, reproduction and carcass quality. In addition, LB can partially replace concentrate, serve as a delivery vehicle for additives such as enzymes and drugs and mediate the distribution of grazing livestock. This paper classifies and analyzes representative research; discusses the types, ingredients and current status of the utilization of LB; and systematically reviews the processing technology, quality assessment, influencing factors of intake, action mechanism and application. This review can provide a basis for the development, popularization and application of novel LB products. Full article
