Summary: The limited usability of rose waste hampers the development of a sustainable circular rose cultivation industry. The unfavorable properties of rose horticultural waste, such as high lignin content in stems and high polyphenol levels in flowers and leaves, pose challenges for reusing it. This study aimed to explore the potential of composting rose waste with other available green wastes or mature rose compost to obtain improved compost with high fertilizing capacity. The results showed that all mixtures resulted in stable and mature compost after six months, with suitable macro- and micro-nutrient concentrations. The ligneous nature of rose waste does not prevent an effective composting process, but an extended maturation phase could be preferred for optimal results. Additionally, mature rose compost demonstrated a high disease suppressive capacity against common rose pathogens.

Summary: The COVID-19 pandemic has resulted in extensive plastic pollution from the use of PPE, particularly polypropylene (PP). Weathering of exposed PPEs leads to contamination and the formation of microplastic (MP) and nanoplastic (NP) pollution, acting as a vector for COVID-19 transmission. Traditional waste management practices need to be updated to prevent this potential ecological catastrophe. This study investigates post-pandemic scenarios of MP/NP pollution and proposes an integrated approach for the recycling of PP-based plastic waste, achieving environmentally friendly and cost-effective recovery of crude oil, solid char, hydrocarbon gases, and construction materials.

Summary: The need for sustainable and renewable alternative fuel sources is increasing due to limited fossil fuel resources and rising global fuel consumption. Waste tyres, with their high calorific value, are considered ideal raw material candidates for alternative fuels. This article examines studies in which oils produced from waste tyres by pyrolysis were tested as fuel in aviation gas turbine engines. The performance and emissions of the fuels were evaluated, showing that waste tyre pyrolysis oil can be used as an alternative fuel in gas turbine engines, with some improvements needed.

Summary: In tanneries, proper management of limed fleshing can help reduce pollution and protect the natural environment. This study demonstrated that limed fleshing can be converted into nutrient-enriched compost without any pretreatment, using a simple and adaptable technique. The quality of the compost was evaluated based on its nutrient content and the compost met the requirements. Furthermore, the composting process effectively eliminated pathogenic organisms and reduced the volume of solid waste generated in the tannery.

Summary: The aim of this study was to review and discuss the management and recycling of the solid fraction of anaerobic digestate through the composting process in the context of circular bioeconomy and sustainable development. The conversion of the solid fraction into compost can be considered as a novel process-enhancing supplement for land reclamation. Additionally, the solid fraction of the digestate is a valuable substrate for compost production, both as a monosubstrate and as an additive for other raw materials to enrich organic matter. These findings serve as a reference for improving the composting process of anaerobic digestate solid fraction, implementing it in a modern bioeconomy perspective, and providing a guideline for effective waste management.

Summary: This study demonstrates for the first time that ordinary residents can correctly conduct household-level indoor composting to manage urban kitchen waste at the source. Results show that the composting temperature decreases with the decline of biodegradable organic substances, and the physiochemical characteristics of the compost vary significantly towards maturation. Continuous organic humification also occurs during indoor composting.

Summary: The level of nitrate in water is increasing worldwide due to the widespread use of inorganic nitrogen fertilisers and animal manure. Nitrate is highly soluble in water and humans are exposed to it through various routes, including water and food. Different methods, such as ion exchange and adsorption, can remove nitrate from water, but adsorption is preferred due to its simple design and satisfactory results with modified or mineral-based adsorbents. Adsorbents derived from biomass waste have high adsorption capacities for nitrate. This review paper provides a comprehensive survey of nitrate pollution sources, human exposure routes, health effects, and the development of low-cost efficient adsorbents for water purification.

Summary: The adsorption and transformation of tetracyclines on SDS surfactant-modified alpha-Al2O3 particles were investigated. The modified adsorbents showed significantly enhanced adsorption compared to the unmodified adsorbents. Optimal conditions were determined to be pH 4, NaCl 1 mM, 180 min contact time, and adsorbent dosage of 25 mg.mL-1. The maximum adsorption capacities were 320, 85, and 91 mg.g-1 for TC, OTC, and CTC, respectively. The SDS-modified alpha-Al2O3 particles could be effective adsorbents for removing tetracyclines from aqueous solutions.

Summary: The paper proposes a novel deep learning-based prediction framework, aTCN-LSTM, for accurate cooling load predictions. The framework utilizes a gate-controlled multi-head temporal convolutional network and a sparse probabilistic self-attention mechanism with a bidirectional long short-term memory network to capture both temporal and long-term dependencies in the cooling load sequences. Experimental results demonstrate the effectiveness and superiority of the proposed method, which can serve as an effective guide for HVAC chiller scheduling and demand management initiatives.
