Circular economy, bioeconomy, and sustainable development goals: a systematic literature review

Environmental Science and Pollution Research, Journal Year: 2023, Volume and Issue: unknown

Published: Sept. 13, 2023

The circular economy (CE) and bioeconomy (BE) are recognized as potential solutions for achieving sustainable development, yet little research has examined their contribution to the United Nations' Sustainable Development Goals (SDGs). In this study, we conducted a bibliometric analysis of 649 articles published between 2007 2022, well systematic literature review 81 articles, assess extent which CE BE communities have addressed SDGs. Our identified 10 gaps including limited number empirical quantitative papers, particularly in context BE, underrepresentation developing regions such Latin America Africa literature. main finding reveals that community primarily focuses on SDG 12, Responsible Consumption Production, followed by 9, Industry, Innovation, Infrastructure; 7, Affordable Clean Energy; 6, Water Sanitation. community, other hand, 9 12. However, both lack attention social SDGs quality education, poverty, gender equality. We propose combination known bioeconomy, could help countries achieve all Further is needed develop implement policies address these promote development. sense, our study an important gap needs more future.

The potential role of biomethane for the decarbonization of transport: An analysis of 2030 scenarios in Italy

Applied Energy, Journal Year: 2023, Volume and Issue: 355, P. 122322 - 122322

Published: Nov. 16, 2023

This paper aims at evaluating the best allocation of potential biomethane generation for decarbonization transport system, presenting a case study in Italy. The country has some peculiar features, such as several operating biogas plants, additional feedstock biogas/biomethane generation, well-developed natural gas network and established relevant uses different final sectors, including transport. Based on current estimates sustainable by 2030, ranging from 2.3 to 7.6 billion cubic meters depending scenario, analysis compares technologies distribution use biomethane. results confirm interesting contribution decarbonizing Italian system: can lead 2.33–4.37 MtCO2e savings, mix application. On national basis, annual climate emission savings 2030 range 10.0 26.7 MtCO2e, scenario. Additional 3.1–8.1 MtCO2 emissions be avoided if CO2 captured during upgrading stored or reused. proposed methodology could used extend other countries, European context.

Biomethane Production from the Mixture of Sugarcane Vinasse, Solid Waste and Spent Tea Waste: A Bayesian Approach for Hyperparameter Optimization for Gaussian Process Regression

Fermentation, Journal Year: 2023, Volume and Issue: 9(2), P. 120 - 120

Published: Jan. 26, 2023

In this work, sugarcane vinasse combined with organic waste (food and wasted tea) was demonstrated to be an excellent source of biomethane synthesis from carbon-rich biowaste. The discarded tea trash might successfully used generate bioenergy. uncertainties costs associated experimental testing were recommended decreased by the effective use contemporary machine learning methods such as Gaussian process regression. training hyperparameters are crucial in construction a robust ML-based model. To make autoregressive, fine-tuned employing Bayesian approach. value R2 found greater during model test phase 0.72%, assisting avoidance overtraining. mean squared error 36.243 21.145 phase. absolute percentage under 0.1%, which 0.085% throughout model’s research that combination trash, food may viable for generation. methodology approach tuning regression is efficient method prediction despite low correlation across data columns. It possible enhance sustainability paradigm direction energy security via usage agroforestry waste.

Sustainable Management Strategies for Fruit Processing Byproducts for Biorefineries: A Review

Sustainability, Journal Year: 2024, Volume and Issue: 16(5), P. 1717 - 1717

Published: Feb. 20, 2024

The fruit processing industry generates enormous amounts of byproducts, which are primarily removed through landfill or incineration. However, these processes cause carbon dioxide and methane emissions release dioxin into the environment. management byproducts is important for reducing amount food waste that sent to landfills developing strategies reuse products valorization economic added value. Fruit rich sources bioactive compounds fermentable nonfermentable sugars. Therefore, materials very attractive feedstocks integrated multifeed biorefineries coproduce a wide range natural bioenergy. studies presented here have shown sustainable managing via biorefinery approach achieve full circular economy. project proposed five main phases, namely, pretreatment, extraction, dark aerobic fermentation, anaerobic digestion, post-treatment, as well two additional pathways generate bioelectricity. When choosing appropriate directions concept, technoeconomic analysis should be carried out, considering type biomass its availability at site throughout year production. Applying concept in closed-loop technology promising way enhance efficiency decrease environmental influence accordance with development.

Techno-enviro-economic assessment of bio-CNG derived from Palm Oil Mill Effluent (POME) for public transportation in Pekanbaru City

Renewable energy focus, Journal Year: 2024, Volume and Issue: 49, P. 100569 - 100569

Published: March 26, 2024

Indonesia possesses the greatest potential in world for bio-compressed natural gas (bio-CNG). This bio-CNG is purified from biogas that generated decomposing organic liquid waste at palm oil mills (POMs). Unfortunately, this great has not been utilized much due to several obstacles such as remote location of POMs, transportation mode, and utilization purposes. These factors have a significant impact on feasibility selling prices. However, case study conducted Riau province showed by clustering selecting appropriate modes, generating additional income carbon trading, price can be achieved. The resulted obtaining two clusters seven POMs were spread over 30km radius Pekanbaru City. Bio-CNG substitute 97 % gasoil bus fuel, trucking was found result lowest price, which 10.7 USD/MMBTU. With minimum reach 4.84 contributes reducing greenhouse emissions, which, turn, increase economic value bio-CNG. pattern usage selection mentioned above should considered when utilizing resulting biogas-POME purification. It still necessary provide supportive policies government.
