“…Physical treatments need lower energy but are less effective, and chemical treatment is an intermediate choice [132]. The catalyst in liquid streams could be regenerated depending on its concentration, which relies mainly on the catalyst type, its formulation, and the operational conditions that it was exposed to [132][133][134]. Water reuse strategies and technologies are restricted by the suspended solid content.…”

Sustainable development is the common goal of the current concepts of bioeconomy and circular economy. In this sense, the biorefineries platforms are a strategic factor to increase the bioeconomy in the economic balance. The incorporation of renewable sources to produce fuels, chemicals, and energy, includes sustainability, reduction of greenhouse gases (GHG), and creating more manufacturing jobs fostering the advancement of regional and social systems by implementing the comprehensive use of available biomass, due to its low costs and high availability. This paper describes the emerging biorefinery strategies to produce fuels (bio-ethanol and γ-valerolactone) and energy (pellets and steam), compared with the currently established biorefineries designed for fuels, pellets, and steam. The focus is on the state of the art of biofuels and energy production and environmental factors, as well as a discussion about the main conversion technologies, production strategies, and barriers. Through the implementation of biorefineries platforms and the evaluation of low environmental impact technologies and processes, new sustainable production strategies for biofuels and energy can be established, making these biobased industries into more competitive alternatives, and improving the economy of the current value chains.

“…In order to understand the CDA, a new Fe II -Cu II -based BmDAE, Fe II (CN) 6 -[Cu II (dien)(H 2 O)] 2 (20), in which the ferrocyanide unit can only provide its inhibiting functionality but not a signal-transducing function, was synthesized. 38 Complex 20 is a stable BmDAE owing to the four negative charges in its ferrocyanide donating unit (DG1 = À30.4 kJ mol À1 ). The [Fe II (CN) 6 ] 4À unit in 20 uses two of its cyano-units to bridge with two Cu II receptors, as verified by ESI-MS and FTIR.…”

“…A variety of fluorescence and colorimetric probes for the recognition of cyanide ion is established on coordination with metal ions or complex, displacement of copper ion ,,− from copper complex, hydrogen-binding interaction, − proton transfer, − and reaction-based. − However, for the detection of CN – in biological environment, it is very significant to develop a new strategy or method to detect CN – at very low concentrations in 100% aqueous medium. This challenge could be overcome by introducing the cyanide receptors on the surface of the vesicle.…”

Detection of environmentally important ion cyanide (CN–) has been done by a new method involving displacement of both metal and indicator, metal indicator displacement approach (MIDA) on the vesicular interface. Terpyridine unit was selected as the binding site for metal (Cu2+), whereas Eosin-Y (EY) was preferred as an indicator. About 150 nm sized nanoscale vesicular ensemble (Lip-1.Cu) has shown good selectivity and sensitivity for CN– without any interference from other biologically and environmentally important anions. Otherwise, copper complexes are known for the interferences of binding with phosphates and amino acids. The Lip-1.Cu nanoreceptor also has the possibility to be used for real-time colorimetric scanning for the released HCN via enzymatic reactions. Lip-1.Cu has several superiorities over the other reported sensor systems. It has worked in 100% aqueous environment, fast response time with colorimetric monitoring of enzymatic reaction, and low detection limit.
