Growing population, industrialisation, and demand for resources put pressure on the delicate balance of planet’s ecosystems. From alternative sources energy, healthier foods, cleaner water, an overall more sustainable economy, integration microalgae in various industries, that otherwise are based practices hurt environment, could be a successful solution. To reach goal, further research is required complex relationship between growth parameters (temperature, light intensity spectrum, nutrient distribution, inhibiting factors, so on). The scientific community successfully used to produce pigments, biofuel, animal fodder, methods sequestering heavy metals, toxic compounds from much more. In this review article, we approach use municipal wastewater treatment, mainly using nitrogen phosphorous present water as nutrients. Data were collected articles published last 7 years (2018–2024). results show very efficient at N P wastewater, well carbon, converting them high-value substances (proteins, lipids, carbohydrates, etc.) with applications multiple industries.

Challenges, progress, and future perspectives for cyanobacterial polyhydroxyalkanoate production

Reviews in Environmental Science and Bio/Technology, Год журнала: 2024, Номер 23(2), С. 321 - 350

Опубликована: Май 23, 2024

Abstract Polyhydroxyalkanoates (PHA) are a promising bio-based alternative to traditional plastics derived from petroleum. Cyanobacteria photosynthetic organisms that produce PHA CO 2 and sunlight, which can potentially reduce production costs environmental footprint in comparison heterotrophic bacteria cultures because (1) they utilize inorganic carbon sources for growth (2) do not require intensive aeration oxygenation. Moreover, supplementing precursors such as propionate, acetate, valerate, etc., be used obtain various copolymers with plastic customizable properties the classical homopolymers, polyhydroxybutyrate, PHB. This critical review covers latest advances production, including recent discoveries metabolism interplay between glycogen new insights into cultivation strategies enhance accumulation, purification processes. also addresses challenges suggests potential solutions viable industrial PHAs process.

Exploiting outcomes of life cycle costing to conduct coherent screening social life cycle assessments of emerging systems: a case study of microalgae biorefineries

The International Journal of Life Cycle Assessment, Год журнала: 2025, Номер unknown

Abstract Purpose Microalgae are considered a promising source of bioenergy and high value-added products that could help face the rising demand for energy raw materials. However, microalgae systems entail consumption materials energy, with potential environmental, economic, social costs. While environmental economic impacts have been analyzed in literature, dimension has barely explored. In this article, life cycle assessment (S-LCA) is applied to identify main contributors risks. Methodology paper, an approach proposed exploit outcomes Life Cycle Costing (LCC) study as input data model evaluate biorefinery schemes. Such helps ensure consistency between assessments, while facilitating gathering context scarcity typical emerging technology. Priority levels stakeholder categories impact subcategories assigned based on literature. Workers local communities were identified stakeholders highest priority, related such health safety issues fair salary former employment latter. An inventory was built, using PSILCA database v2.0 Starter openLCA software, together cost estimates from LCC real experiments at lab pilot scale. Results According results, contribution risks biogas production expected be linked anaerobic digestion. Some contributors, both cultivation digestion, basic chemicals market public sewage activities, civil engineering construction, metal machinery production. The geographical distribution depends category subcategory. Since many activities value chain assumed happen Spain, non-negligible part take place there. other countries minor contributions total working time found risk indicators fatal accidents. Finally, three scenarios compared, considering Chinese, French, or Spanish context, which lead significant differences. Conclusions This aims highlight importance assessing different dimensions sustainability coherent manner. Furthermore, it provides useful information hints microalgae-based sector available generic S-LCA databases, their dependence locations activities. Despite limitations, conducting assessments tools key better understand need widening scope studies.

Exploring the role of social life cycle assessment in transition to circular economy: A systematic review

Resources Conservation and Recycling, Год журнала: 2024, Номер 207, С. 107702 - 107702

Опубликована: Май 17, 2024

Transitioning to a circular economy (CE) may create unintended social consequences. This systematic review analysed 45 published studies from 2009 2023 that evaluate these consequences using lifecycle assessment (S-LCA), tool based on the UNEP Guidelines. Most focused activities like energy recovery and material recycling rather than reuse, remanufacturing, repair. Worker-related issues health, safety or fair wages were more frequently reported impacts consumers society. Challenges in S-LCA application for CE include defining system boundary, identifying affected stakeholders, selecting relevant impact categories indicators, obtaining verifiable data inventory, addressing subjectivity interpretation. A solution identified through was enhance stakeholder involvement across industries identify emerging risks during transition CE. Periodically revising Guideline will provide uniform framework continued use of evaluating
