The presidents of the chemical societies of France (SFC), Germany (GDCh), Japan (CSJ), the Netherlands (KNCV), the UK (RSC), and the USA (ACS) recently pledged on behalf of about 300,000 members to "work together to promote global sustainable development, demand responsible use of resources, and ensure that the next generation of scientists protects and maintains the well-being of Earth and its inhabitants." They deem this issue an urgent one, and that chemistry is absolutely essential to the development of solutions.

Nonregenerative Natural Resources in a Sustainable System of Energy Supply [Full Paper]
Rare and precious: Following the lead taken by the EU in energy and climate policy, a shift from fossil fuels to regenerative energy will have occurred globally by the second half of this century. This will be accompanied by a strong demand for other exhaustible raw materials, in particular metals. The terms “sustainability”, “depletion” and “scarcity” are examined in the context of mineral supply and the situation with regard to some rare metals is discussed.

Use of Industrial Waste for the Manufacturing of Sustainable Building Materials [Full Paper]
Concrete values: In this study, we develop a new and interesting way of valorizing granite waste (GW) by using it as a supplementary material in cement-based mortars, which are among the most widely used products in building and civil engineering works. The physico-chemical and mineralogical characteristics of GW, and the physical and mechanical properties of the new formulated mortars, are studied. The valorized waste and the new mortar exhibit ability in the photodegradation of organic dye.

Synthesis of Aryl(di)azinyl Ketones through Copper- and Iron-catalyzed Oxidation of the Methylene Group of Aryl(di)azinylmethanes [Communication]
Sustainable Oxidations: An oxidation method to transform aryl(di)azinylmethanes into aryl(di)azinyl ketones is described. Base metals (copper and iron) as catalysts in combination with O2 as the oxidant are used, which renders this method sustainable. The utility of this method is illustrated by the synthesis of 6-(4-methylbenzoyl)pyridine-2-carbaldehyde, which is an intermediate in the preparation of the drug Acrivastine.

Energy from Plants and Microorganisms: Progress in Plant–Microbial Fuel Cells [Minireview]
Down to the roots: Plant–microbial fuel cells convert solar energy into electrical power by using microorganisms, which degrade root exudates and pollutants at the anode and pass the electrons to acceptors at the cathode. This setup can provide auxiliary power while reducing the emission of greenhouse gas, that is, methane, from fields.

Conversion of Hemicellulose to Furfural and Levulinic Acid using Biphasic Reactors with Alkylphenol Solvents [Communication]
Plans with plants: The hemicellulose fraction of lignocellulosic biomass is converted to furfural and levulinic acid using biphasic reactors with alkylphenol solvents that selectively partition furanic compounds from acidic aqueous solutions. The furfural and levulinic acid products are valuable compounds for a variety of chemical applications, and they serve as precursors for the synthesis of liquid transportation fuels.

Transfer of the Epoxidation of Soybean Oil from Batch to Flow Chemistry Guided by Cost and Environmental Issues [Full Paper]
Transfer window: A holistic concept for sustainable process development through process intensification due to microprocess technology in combination with novel process windows is presented. Process modeling and simulation linked with simplified cost and lifecycle assessment provide valuable information to guide the ongoing design of a continuously running pilot-process for the epoxidation of soybean oil (see picture).

A–T Base Pairs are More Stable Than G–C Base Pairs in a Hydrated Ionic Liquid [Communication]
A green solvent: Quantitative thermodynamic analyses shows that A–T base pairs are more stable than G–C base pairs in the hydrated ionic-liquid choline dihydrogenphosphate because of specific interactions between DNA bases and choline ions.

Chlorostyrenes in Iron-Catalyzed Biaryl Coupling Reactions [Communication]
An effective protocol for iron-catalyzed biaryl syntheses by coupling chlorostyrenes with aryl Grignard reagents requires only mild reaction conditions and tolerates various functional groups. The underlying activation of deactivated aryl chlorides proceeds through a rate-determining coordination of the catalyst to the vinyl substituent and subsequent haptotropic migration along the conjugated π system to the site of C-Cl bond cleavage.

Green and Inexpensive Choline-Derived Solvents for Cellulose Decrystallization [Communication]
A new generation of cheap and sustainable choline-derived ionic solvents is reported. These solvents are capable of rapidly dissolving and decrystallizing microcrystalline cellulose (MCC) in only a few minutes, thus offering an eco-efficient alternative to the traditional use of imidazolium-based ionic liquids (see scheme).

Homogeneous Catalysis of Valeronitrile Hydrolysis under Supercritical Conditions [Full Paper]
Supercritical tuning: The outstanding characteristic of water as a reaction medium is the possibility of tuning its properties by changing the temperature and pressure. In combination with small amounts of sulfuric acid, even the most resistant compounds show significant conversion within seconds. The kinetics of the hydrolysis of valeronitrile are investigated under supercritical conditions, which results in remarkable yields of valeric acid.

Synthesis of Renewable Bisphenols from Creosol [Full Paper]
Plastics, naturally: Creosol (2-methoxy-4-methylphenol), which can be readily derived from lignin, is selectively condensed with a series of aldehydes under stoichiometric conditions. The resulting compounds are isolated in good yields and purities. This method can be used to produce molecules that may have applications as renewable replacements for bisphenol A.
