“…Direct and catalytic thermal pyrolysis of algae, especially microalgae for biofuels (bio-oil, biodiesel, syngas, etc. ) and biochar production is a major research focus in 2019 (Anto et al 2019;Ashokkumar et al 2019;Cruce and Quinn 2019). Algae biofuels are renewable and represent a promising alternative to fossil fuels; its production could mitigate the issue of the excessive use of fossil fuels (Anto et al 2019).…”

Biochar, derived from thermal pyrolysis of biomass, has been regarded as a low-cost, sustainable and beneficial material and widely applied in agriculture, environment and energy during the last two decades. To elucidate the research status timely and future trends in biochar field, CiteSpace is used to systematically analyze the related literature retrieved from the Web of Science core collection in 2019. Based on the keywords clustering analysis, it was found that "biochar production", "organic pollutants removal", "heavy metals immobilization", "bioremediation" were the main hotspots in research covering biochar. "Bioremediation" is an emerging topic and deserves extensive attention due to its highly effective and environmentally friendly treatment of pollutants. Improving the phytoremediation effect, immobilizing functional microorganisms on biochar, and using microorganisms as raw materials to produce biochar were the common methods of biochar-assisted bioremediation. While studies focused on "soil quality and plant growth" and "biochar and global climate change" decreased, investigations concentrated in the toxicity of biochar to soil biota and ruminants are sustainably growing. Research on direct and catalytic thermal pyrolysis of green waste (mainly microalgae) for biofuels (bio-oil, biodiesel, syngas, etc.) and biochar production is increasing. Converting municipal wastes (e.g., sewage sludge, fallen leaves) into biochar through pyrolysis was a suitable treatment for municipal waste and became a popular topic in recent time. Moreover, the biochar produced from these municipal wastes exhibited excellent performance in the removal of pollutants from wastewater and soil. This review may help to identify future directions in biochar research and applications.

“…Biofuels derived from microalgae are still not commercially viable because their costs are higher than gasoline (Cruce and Quinn, 2019). Thus, the sustainability of projects that aim to cultivate microalgae for the production of biofuels and other bioproducts is generally evaluated using technoeconomic analysis and/or life cycle assessment (LCA) (Grierson et al, 2013).…”

The aim of this study is to provide a bibliometric analysis and mapping of existing scientific papers, focusing on microalgae cultivation coupled with biomass production and bioremediation of wastewater from cassava, dairy, and coffee industries. Using the Web of Science (WoS) database for the period 1996–2019, a search was performed using a keyword strategy, aiming at segregating the papers in groups. The keywords used in this search were “wastewater treatment,” “microalgae,” “cassava,” “dairy,” and “coffee” for the first step, resulting in 114 papers; for the second step, we used the keywords “wastewater treatment,” “biomass productivity,” “microalgae,” “economic viability,” and “environmental impacts,” which resulted in 29 scientific papers. In these papers, keywords such as “carbon dioxide biofixation” and “removal of nutrients by the production of biomass by microalgae” followed by “environmental and economic impacts” were highlighted. Some of these papers also presented an analysis of the economic feasibility of the process, including costs of production systems, which reveal the state-of-the-art setup required to make the cultivation of microalgae economically viable. Research in eco-industrial parks is needed to improve the integration of microalgae production systems using wastewater as a source of nutrients, aiming to achieve the global goal of bioremediation and clean alternatives for renewable energy generation.

“…They showed that for hydrothermal liquefaction, protein extraction, fractionation and novel pathways, the results were comparable to other biofuel studies, at $5.37, $4.44, $4.31 and $11.13 gge −1 respectively. They also showed that mixing the algal biorefinery with the treatment of wastewater surprisingly provided only minor benefits to system economics [47].…”

Agribusiness could be the most promising sector for algae biomass exploitation and popularization. In this paper we summarize the scope of interests in agribusiness which can be fulfilled with algae exploitation. A high growth rate, a high ability to bind carbon dioxide and the potential to accumulate biogenic elements and light metals mean that algae can be used as a raw material for production of biofertilizers, biopesticides, feeds and feed additives. The use of the means of agricultural production based on algae can take place both in organic and conventional agriculture. The development of innovative and low-cost technologies of algae production, including the possibilities of their use in rural areas, provide a basis for changes, improvements and modifications to the existing solutions in the scope of production and use of industrial means of agricultural production. We also show that although there are quite diverse methods of production, and various micro and macro species diversified in chemical content, the economic viability of algae-based agribusiness is still in its infancy. The wide utilization of algae for food product manufacturing opens alternative ways for food acquisition, protecting both the food supply and the planet’s resources. The sustainability aspects of mass algae production implementation seem to be indisputable regarding possible benefits resulting from such technology. The versatility of algae application in food products, along with the very high nutritive and bioactive profile of this ingredient, make this resource of high importance in a low-emission economy.
