“…Initially, this raw material was seen as a promising option to reduce the extraction and use of traditional fuels. However, worries have arisen about the use of food crops as raw materials and their impact on arable land, biodiversity and global food needs [14][15][16][17]. Biofuels of the second generation are produced from non-food lignocellulose or wood biomass as well as agricultural waste.…”

Countries around the world recognize the numerous social, economic and environmental advantages of promoting liquid biofuels. They invest in its development and introduce tax incentives for its manufacture and tariffs of production regulation. In most studies, the process of synthesizing fatty acid esters takes a long time from 1 to 8 h. In this work, the synthesis of fatty acid esters was carried out in the range of volumetric ratios of ethanol to linoleic type oil in order to increase the kinetics of the process. The main parameters of the synthesis were studied by use of magnetic stirred tank reactors in a parallel reactor system, H.E.L. The synthesis was carried out in the presence of a homogeneous alkaline catalyst. The volumetric ratio of ethanol to oil was maintained at 1:1, 2:1, 3:1, 4:1 and 5:1. The amount of catalyst added to the reaction mixture ranged from 0.25 to 2.5% by the weight of the reaction alcohol. The dryness of ethanol varied from 91 to 99%. Effective process conditions have been established to reduce the reaction time from 2.5 h to 5 min while maintaining a high degree of conversion. The results obtained during the study suggest the possibility of using a continuous reactor to produce fatty acid esters from linoleic raw materials containing up to 16% of free fatty acids. This also means the possibility of using second generation biofuel feedstock.

“…It has a large specific surface area about 100 m 2 /g [17,20]. Because of its high surface area, high thermal and chemical stability, and high mechanical power, alumina is commonly used as a catalyst or additive in the industrial sector in many process industries as prior highlighted such as hydrogen processing and petroleum refining [15,21,22]. As a result, this study aimed to synthesise γ-Al2O3 from aluminium waste and investigate the thermal resistance of the synthesised samples at different reaction temperatures using TGA analysis.…”

The discarded empty aluminium beverage cans can pose a serious environmental contamination issue. Recently, studies are now focusing on reducing and utilising solid wastes which have grown to be a significant environmental concern. Thus, this study focuses on producing γ-Al2O3 from readily available aluminium garbage cans using a Sol-gel technique and analysing its thermal properties using TGA analysis. The effect of the reaction temperatures was further investigated to comprehend the synthesis of alumina at (room temperature, 50 °C, and 70 °C) at a fixed aging duration of 12 h. Experimental findings demonstrated the potential of producing γ-Al2O3 from used aluminium cans, which may then be used as sustainable catalysts and catalytic supports for a variety of applications. The results showed that all the synthesised alumina had a good result with a maximum weight loss less than 5%; this reflected its strong stability. The alumina that was created at 70 °C reaction temperature recorded the lowest weight loss and the highest residue at 2.78% and 97.22%, respectively.

Economic and environmental problems are closely related, and solving some of them, the others cannot be solved. The state of the environment directly forms the potential of the economic sphere. For example, resources for industrial enterprises are formed in the natural environment, and the capacity of plants and factories depends on resources’ quantity. The amount of money to be spent on the purchase and installation of treatment plants, on the measures to eliminate water, air and soil pollution, depends upon the profit. Each country has its own list of environmental problems related to the economy. They are engaged in their elimination at the state level, but first of all the responsibility for the consequences is the burden of companies’ management. The active development of the economy should not adversely affect the state of the environment. Both individual enterprises and whole states should control the economic and environmental situation in order to achieve a balance and solve global problems. The most important form of interaction between the state and business in solving economic-and-environmental problems is the introduction of zero waste technologies in all their diversity and achieving their multiplicative effect. The paper shows the relationship between environmentally-oriented innovative development of the economy and the introduction of zero waste technologies.
