A method comparing the technologies used in the industry processing animal tissues with the best available techniques (BAT) based on the principle of an integrated pollution prevention and control (IPPC) is suggested. The method compares individual mutually comparable BAT indicators expressed by quantities indicating the standard of the method compared in relation to BAT. The method can be applied to compare the environmental standard of the equipment to which the Act No. 76/2002 Dig. of the relevant production branch relates.

Abstract The carbon dioxide concentration in the atmosphere has reached extremely high levels, generating environmental concerns. Unfortunately, despite the climate change, CO2 is not included nowadays as a key environmental issue in Best Available Technique (BAT) reference documents (BREF). Industrially, the widespread industrial technology to capture CO2 is the chemical absorption using aqueous monoethanolamine (MEA) at 30%wt, which is the basis of comparison for novel alternative techniques in the literature and seems a suitable candidate to be proposed as Best Available Technique. Nevertheless, there is an intense research to find alternative solvents that decrease the energy consumption for carbon capture and many solvents are claimed in the literature to outperform MEA. A novel empirical surrogate model and exergy balances are used to confirm that MEA is still the best candidate to be proposed as Best Available Technique. The surrogate model proposed in this study properly regresses the CO2 gas liquid equilibrium data. The regressed parameters of the model are tabulated in this study for many aqueous alkanolamines and their mixtures, being the basis for computationally inexpensive chemical absorption column design. The surrogate model parameter considering the temperature is related with the chemical absorption energy and the consumed energy for solvent recovery. The obtained results show that none of the considered alkanolamine outperforms MEA in all the considered aspects, i.e. energy and solvent flowrate. MEA minimum flowrate is 15.62 mol solvent/mol gas and its heat of absorption regression parameter is − 27,745 J/mol. The proposed mathematical method is useful as a fast assessment for other novel alternatives that will be proposed in the future, providing energetically more efficient and cleaner technologies for CO2 capture.

<p>Oil spill cleanup is a complex and expensive activity. There are several commonly used techniques available today. The paper suggests criteria for the selection of the best available technique that could be employed in case of oil spills in the Mediterranean Sea under specific circumstances, i.e. calm sea and presence of marine protected areas, in order to prevent pollution. Not all the available techniques could be considered. Only three of them could be selected, as these allow the preservation of natural areas, as well as the protection of threatened species and their habitats. The Analytic Hierarchy Process method has been preferred among the great variety in multi-criteria decision making tools for the selection of the best available technique. This is a widespread decision support tool suitable for the selection of the best alternative solution to a particular problem. Twenty professionals with different expertise evaluated, through pair-wise comparisons, the alternative options to choose in a protected area. The selected emergency cleanup technique must be readily available and operational in a short time. The results give a preference to new sorbents, followed closely by the magnetic nanocomposites technique.</p>
