Reliance on plastic has resulted in the widespread occurrence of micro-/nanoplastics (MNPs) aquatic ecosystems, threatening food web and whole ecosystem functions. There is a tight interaction between MNPs microalgae, as dominant living organisms fundamental constituents at base web. Therefore, it crucial to better understand mechanisms underlying interactions particles well role microalgae removing from ecosystems. In addition, finding suitable route for further utilization MNP-contaminated algal biomass great importance. The present review article provides an interdisciplinary approach elucidate microalgae–MNP subsequent impacts microalgal physiology. degradation environment differences micro- nanoplastics are discussed. possible toxic effects growth, photosynthetic activity, morphology, due physical or chemical interactions, evaluated. potential cultivation and/or harvesting, together with safe routes biofuel production, suggested. Overall, current represents state-of-the-art overview MNP generation consequences their accumulation environment, providing new insights into integrated removal bioenergy production.

The present study investigates the effect of small-sized aluminum oxide nanoparticle concentration and engine load on emissions performance parameters a single-cylinder diesel connected to an AC generator. Response surface methodology (RSM) based central composite design (CCD) was employed simulate experiment. ultrasonication-assisted preparation method has been used mix (D) with two different concentrations oxide, namely 50 ppm 100 ppm. tested fuels are called D, (D + 50AL2O3), 100AL2O3) accordingly. tests were carried out at various loads 0.9, 1.8, 2.7 kW rated speed 3000 rpm without modification. evaluated characteristics nitrogen (NOx), hydrocarbons (HC), carbon dioxide (CO2), monoxide (CO), brake-specific fuel consumption (BSFC), brake thermal efficiency (BTE), exhaust gas temperature (EGT). According analysis variance (ANOVA) results, experimental outputs found be in good agreement that predicted. Furthermore, results revealed D 50Al2O3 favorably reduced harmful all investigated. For instance, NOx, HC, CO decreased by 32.28%, 21.74%, 20%, respectively. In addition, BTE improved 4.91% compared pure diesel. aforementioned potential nanoparticles could effectively reduce enhance performance. small size 11 nm low only (mixed diesel) positive technical, environmental, economic perspectives applicability proposed nanofuel.

Abstract Background In addition to the other uses for macroalgae, since 1970s, there has been interest in using macroalgae as a source of biofuels, due high rates productivity and intrinsic advantages over biofuel crops such not requiring land use or significant freshwater input. A wide range conversion processes exist but anaerobic digestion was one first demonstrated is still widely proposed pathway. To be economically viable scalable within Europe, industry will need based on small number fast growing, high-yielding European species. There body scientific work seaweeds via digestion. Main text These studies demonstrate that efficiency this pathway highly variable between species, processing techniques, composition digestor conditions. paper, we review specifically linking it candidate species bio-energy cultivation with aim promote future development macroalgal sector allow better alignment requirements production from macroalgae. Conclusions Overall, seaweed offers opportunities large-scale energy which avoids some issues have faced previous generations are key challenges overcome ensure wider adoption economic viability. (1) Optimising biomass an uniform feedstock optimised increase desirable characteristics sugar content carbon nitrogen ratio reduce inhibitory factors halogenated secondary metabolites, sulphur heavy metals. (2) Improving through co-digestion, pre-treatments tailored microbial communities, feasible technology. (3) Developing communities capable utilising diverse polysaccharides being tolerant saline conditions associated them. Addressing these deliver benefits towards cultured seaweeds.

Microplastics (MPs), as frequent pollutants, persist in aquatic environments and have an impact on the growth biomass production of microalgae. This study employed MPs polyethylene (PE), polystyrene (PS), polypropylene (PP) at concentrations 250 mg/L with MP sizes 50, 100, 300, 500 µm to investigate their influences bio-production Scenedesmus quadricauda. The results revealed that suppressed S. quadricauda increased algal lipid production. order terms inhibitory effect was following: PP > PS PE. size sensitivity 50 100 300 µm. In culture, inhibition microalgal (inhibition rate: 49.26%) accumulation lipids (total content: 65.40%) were most significant, especially neutral content. Additionally, scanning electron microscopy (SEM) Fourier-transform infrared spectroscopy (FTIR) analyses proved rough surface led high aggregation microalgae, reduced intensities protein-, lipid-, carbohydrate-related bands affected structure cells.

Seaweeds are among the most important biomass feedstocks for production of third-generation biofuels. They also efficient in carbon sequestration during growth and produce a variety high-value chemicals. Given these characteristics together with relatively high carbohydrate content, seaweeds have been discussed as an ideal means CO2 capture biofuel production. Though biofuels emerged some best alternatives to fossil fuels, there is currently no large-scale or mainstream use such liquid fuels due many technical challenges costs. The present study describes concept coastal marine biorefineries cost-effective sustainable approach from seaweeds, well atmospheric storage (CCS). suggested refinery system makes resources, namely seawater, seaweed, microorganisms. Firstly, extensive screening current literature was performed determine which technologies would enable emergence novel biorefinery its merits over conventional refineries. Secondly, investigates various scenarios assessing potential sequestration. We demonstrate that removal 100 Gigatons excess using seaweed farms can be achieved around 4 months less than 12 years depending on area under cultivation species. total bioethanol could generated harvested 8 trillion litres. In addition, chemicals (HVC) potentially recovered process represent considerable opportunity multi-billion-dollar commercial value. Overall, strong green economy rapid climate change mitigation.
