A Review on the Preparation, Properties, and Mechanism of Lignin-Modified Asphalt and Mixtures
Published on 2026-02-03 by Yu Luo, Guangning Ge, Yikang Yang, Xiaoyi Ban, Xuechun Wang, Zengping Zhang, Bo Bai @MDPI
Abstract: Lignin, an abundant and renewable biopolymer, holds significant potential for asphalt modification owing to its unique aromatic structure and reactive functional groups. This review summarizes the main lignin preparation routes and key physicochemical attributes and assesses its applicability for enhancing asphalt performance. The physical incorporation of lignin strengthens the asphalt matrix, improving its viscoelastic properties and resistance to oxidative degradation. These enhancements are [...]
Our summary: This review discusses the preparation and properties of lignin-modified asphalt (LMA). Lignin enhances asphalt s viscoelastic properties and resistance to degradation through cross-linking and antioxidant mechanisms. Future research should focus on large-scale tests and molecular interactions to optimize LMA performance.

A Comprehensive Review on Sustainable Triboelectric Energy Harvesting Using Biowaste-Derived Materials
Published on 2026-02-03 by Wajid Ali, Tabinda Shabir, Shahzad Iqbal, Syed Adil Sardar, Farhan Akhtar, Woo Young Kim @MDPI
Abstract: The growing demand for sustainable and distributed energy solutions has driven increasing interest in triboelectric nanogenerators (TENGs) as platforms for energy harvesting and self-powered sensing. Biowaste-based triboelectric nanogenerators (BW-TENGs) represent an attractive strategy by coupling renewable energy generation with waste valorization under the principles of the circular bioeconomy. This review provides a comprehensive overview of BW-TENGs, encompassing fundamental triboelectric m[...]
Our summary: This review explores biowaste-derived triboelectric nanogenerators (BW-TENGs) for sustainable energy harvesting. It evaluates various biowaste resources and their triboelectric properties, emphasizing environmental sustainability and multifunctionality. Challenges to large-scale deployment and emerging solutions are also discussed.

Comparative TEA–LCA of CHP, Biomethane, and Hybrid Biogas Utilization Pathways for Poultry Manure with Fruit and Vegetable Waste Co-Digestion Systems
Published on 2026-02-02 by Ayandeji Sunday Ayantokun, Olalekan Joseph Ogunniyi, Tonderayi Syvester Matambo, Ismari Van der Merwe, Charles Rashama, Johan Adam Van Niekerk @MDPI
Abstract: Anaerobic digestion of organic waste offers renewable energy and waste-management benefits, relevant to multiple SDGs. This study evaluates a proposed 50 t/d farm-based biogas plant co-digesting poultry manure (PM) and fruit/vegetable waste (FVW) in South Africa. Five substrate blends (100% PM, 100% FVW, and three PM–FVW mixtures) and three biogas utilization routes (100% electricity via a combined heat and power (CHP) system, 50/50 CHP–biomethane, and 100% biomethane[...]
Our summary: This study evaluates a biogas plant co-digesting poultry manure and fruit/vegetable waste in South Africa. Five substrate blends and three biogas utilization routes were modeled in a TEA and LCA framework. The CHP-only configuration is identified as the most financeable option, with recommendations for improved digestate management to reduce emissions.

A Life Cycle Perspective
Published on 2026-02-02 by Yitong Niu, Nicholas Starrett, Mardiana Idayu Ahmad, Sicheng Wang, Yunxiang Li, Ting Han @MDPI
Abstract: Second-generation bioethanol from food industry lignocellulosic residues offers a promising route toward low-carbon, circular bioenergy systems. However, the reported environmental impacts differ markedly across studies, challenging efforts to assess the true sustainability of these waste-derived bioethanol routes. This review synthesizes current knowledge on the production of bioethanol from key agro-industrial wastes including oil palm empty fruit bunches, sugarcane bagasse, brewers&rs[...]
Our summary: This review analyzes second-generation bioethanol production from food industry lignocellulosic residues. It highlights the environmental impacts and methodological differences in life cycle assessments across various studies. Recommendations for harmonizing practices are provided to support sustainable bioethanol development within circular bioeconomies.

Hourly Attributional Prospective Life Cycle Assessment of the Italian Electricity Grid
Published on 2026-02-02 by Juan Diego Corts Castelblanco, Giuseppe Muliere, Jacopo Famiglietti @MDPI
Abstract: The environmental profile of the electricity grid varies throughout the year, especially with the introduction of renewables, given their high level of discontinuity. Additionally, positive energy districts emerged as a solution for decarbonizing the building sector, thanks to high levels of self-consumed electricity and the benefits of exporting electricity to the national grid. Most life cycle assessment studies assume a retrospective and static background system for these evaluations. This st[...]
Our summary: This study conducts a prospective attributional life cycle assessment of the Italian electricity grid from 2024 to 2040. It highlights the transition towards renewable energy sources, projecting a significant reduction in fossil fuel generation and increased solar and wind contributions. The analysis reveals decreasing climate change impacts and emphasizes the importance of hourly data for understanding seasonal variations in environmental effects.
