“…The intensive livestock sectors and the use of raw manure directly on soil could have a depleting effect on the environment considering the increase of GHG, soil, and water pollution by leaching nutrients and phytotoxic elements. The concentration of many animals in a restricted area requires the introduction of treatments, which permit manure delocalizing [ 27 , 28 , 29 ]. The fast and controlled maturation of the manure led to a product with reduced water content and high content of stabilized OM and nutrients, suitable for application in the apple orchard.…”

In intensive fruit growing systems, the recovery and maintenance of soil fertility play a crucial role in both environmental protection and sustainable support to plant productivity. The circular economy approach adopted at the EU level strongly promotes the use of organic products instead of mineral fertilizers. This work focuses on two different soil improvers, compost from the organic fraction of municipal solid waste digestate (CO) and “matured” manure, produced after a fast and controlled aerobic treatment in an aerated pile (MM), which were applied in three apple orchards with different soil tillage. The soil improvers have been characterized for amendment and fertilizing properties. After the amendment, the soils were sampled twice a year (Spring and Autumn) for three years. Each sample has been characterized for texture, pH, cation exchange capacity, nutrients, soil organic matter, and micronutrients. The amendments obtained differed on C, N, P, and K contents, but had similar biological stability. The main effects on soils were the increasing of N and soil organic matter after compost application, while the use of matured manure mainly act on available P and exchangeable K. The treatments showed significant effects among fields with a linear increasing trend only for compost. Matured manure showed more effects in earlier times. The data collected aim to improve the knowledge about sustainable management of soil organic matter and organic nutrients in intensive fruit-growing agriculture by using local products.

“…For instance, the HTC process water, rich in organic compounds, can be recycled into an AD reactor, improving the methanogenic potential [75,76] and mitigating its phytotoxicity [21,75,77,78]. Also, HTC can be applied as the digestate and provide recovery of valuable nutrients (e.g., N, P) [77,78], addressing the issues associated with the uncontrolled releases of nutrients (overload) in the soil, eutrophication, and spread of pathogenic organisms in the soil [79].…”

This study assesses the status of hydrothermal carbonization (HTC) technology and identifies barriers hindering its commercial viability. Conducting a global survey among HTC companies (with a total of 24 surveys sent), the research evaluates the current landscape, challenges, and future prospects of large-scale HTC operations. Furthermore, it presents a detailed global inventory of existing HTC facilities, illustrating geographical distribution and trends in application. Most of the companies are located in Europe, followed by Asia and North America. With substantial participation from HTC companies, exceeding 62% in the survey (15 companies), the study provides a comprehensive overview of diverse companies, their business models, regulatory challenges, and the overall state of HTC technology. The majority of companies in this study, approximately 80%, offer services in the field of waste management. This paper also explores the potential of HTC in transforming waste management practices, carbon sequestration methodologies, and the development of new materials. Employing a thorough SWOT analysis, the paper advocates for a broader adoption of HTC, emphasizing its transformative capacity in fostering sustainable management of urban, industrial, and agricultural residues, promoting circular economy principles, mitigating climate change, and offering a robust foundation for informed decision-making and sustainable development strategies.

“…The environment can be negatively affected from an ecological point of view also by animal waste, but seen from another perspective, manure can be a valuable resource if it is introduced into the circular economy due to nitrogen and phosphorus, which can be important sources for the production of energy [12]. Yildizbasi [13] considered that an important section of the circular economy is the field of energy, because energy is needed to make some products or perform some services.…”

Renewable energy is produced from natural sources that can regenerate quickly, such as the sun, wind, water, biomass and the earth’s heat. This implies that the resources used do not have a significant negative impact on the environment, which aligns with current concerns for protecting the planet and ecosystems. This study aims to explore the behavior of entrepreneurs regarding the processing of resources that can be introduced in the circular economy and the development of the renewable energy portfolio by transforming horse manure into bioenergy. Employing Structural Equation Modeling (PLS-SEM) and based on an extensive dataset comprising 104 responses from entrepreneurs engaged in or aspiring to participate in the renewable energy sector, this research reveals a noteworthy finding. Contrary to prevailing expectations, it demonstrates that the perceived interest in safeguarding future resources and the environment among these entrepreneurs is currently low. This study not only enriches the understanding of entrepreneurial behavior within the renewable energy domain but also extends the Theory of Planned Behavior. In doing so, it underscores the critical significance of sustainability factors as drivers of future business development and underscores the need for comprehensive policy initiatives that compel greater commitment to renewable energy and circular economy practices.
