In the last decades, sustainable chemical productions have gained remarkable attention due to the increased accountability for environmentally issues leading to an intensification on the use of biomasses based platforms. Biorefinery has been prooved as a sound approach for the conversion of biomasses to raw chemicals integrating several processes ranging from fermentation to thermochemical treatments. Among them, pyrolysis represents a valuable tool for biomass conversion: as a matter of fact, high-quality oil with proprieties like a fuel can be recovered by fast processes run on lignocellulosic biomasses using different reactors designs and process parameters. In the same field, an innovative approach is represented by the use of microwaves as a heating source for pyrolytic conversion. Microwave (MW) induces very fast and volumetric heating but usually require a susceptor able to adsorb MW and dissipate heat after the interaction with the electromagnetic field. Microwave-assisted pyrolysis has been largely used for biomass conversion with a particular emphasis on the production of liquid fractions also known as bio-oils. It finds also a lot of applications as a source of chemicals such as pesticides, mixtures for chemical treatments or employed after purification procedures (i.e. extraction or a fractionating process to isolate the more interesting compounds present, such as acetic acid, levoglucosane, aromatics, and furans.

End of life packaging is nowadays one of the major environmental problems due to its short usage time, the low biodegradability, and the big volume occupied. In this context, gasification is one of the most promising chemical recycling techniques. Some non-recyclable or non-compostable waste gasification plants are already operating such as Enerkem Alberta Biofuels in Canada or the Sierra’s FastOx Pathfinder in California. In this review, we have examined works about plastic gasification from the last fifteen years with a specific focus on polyolefin (PP, PE), plastics mix, and co-gasification of plastic with biomass. For each of these, the best operating conditions were investigated. A very in-depth section was dedicated to supercritical water gasification (SCWG). The most used reactors in gasification processes are fluidized bed reactors together with air or steam as gasifying agents. Tar removal is commonly performed using olivine, dolomite, or nickel based catalysts. SCWG has numerous advantages including the inhibition of tar and coke formation and can be used to remove microplastics from the marine environment. In co-gasification of plastic material with coal or biomass, synergistic effects are observed between the raw materials, which improve the performance of the process, allowing to obtain higher gas yields and a syngas with a high energy content.

End functionalized polylactides are prepared by ring opening polymerization of L-lactide in the presence of stannous octoate (Sn(Oct)2). Three chromophores, 9H-carbazol-ethanol (CA), 9-fluorenyl-methanol (FM), and 2-(4-(2-chloro-4-nitrophenylazo)-N-ethylphenylamino)ethanol (Disperse Red 13, DR), are for the first time used as co-initiators in the polymerization process. The polymerization reaction is initiated by conventional thermal treatment, but in the case of FM, microwave-assisted polymerization is also carried out. CA and FM absorb and emit in the UV portion of the electromagnetic spectrum, whereas DR absorbs in the visible part. The obtained end-capped polylactides derivatives show the same photophysical properties as the initiator, so they are “macromolecular dyes” (MDs) that can be used “as synthesized” or can be blended with commercial poly(lactic acid) (PLA). The blends of PLA with MDs have ultraviolet-visible (UV-Vis) absorption and fluorescence emission features similar to that of MDs and thermal properties typical of PLA. Finally, migration tests, carried out onto the blends of PLA with MDs and PLA with free chromophores, show that MDs are less released than free chromophores both in solution and in the solid phase.

Microwave-assisted pyrolysis is a promising thermochemical technique to convert waste polymers and biomass into raw chemicals and fuels. However, this process involves several issues related to the interactions between materials and microwaves. Consequently, the control of temperature during microwave-assisted pyrolysis is a hard task both for measurement and uniformity during the overall pyrolytic run. In this review, we introduce some of the main theoretical aspects of the microwaves–materials interactions alongside the issues related to microwave pyrolytic processability of materials.

Olive pruning residue is largely formed during cultivation, and is usually disposed through open-air combustion directly in the field, but this habit is a possible source of pollution. The pyrolytic conversion of olive pruning residue has been run in a new and very appealing way using microwave as a heating source and different microwave absorbers in a multimode batch reactor. In this way, olive residue is converted into interesting bio-chemical products with a short pyrolysis time, ranging from 15 to 36 min, and with a peak temperature ranging from 450 K to 705 K according to the different microwave absorber. Thus, a very efficient and selective system was realized, which was able to address the process towards the formation of a large amount of bio-char (up to 61.2%) or a high formation of bio-oil (56.2%) and gas (41.7%) with a very low formation of bio-char (2.1%). However, when carbon and iron were used as microwave absorbers, it was possible to obtain an intermediate amount of bio-char (26-30%) and bio-oil (40 wt%). Bio-oils were collected as dark-brown liquids with low viscosity and density. A bio-oil with a low water concentration was obtained using carbon or iron as the microwave absorber. The bio-oils formed in all experiments contained a very large amount of acetic acid, even when NaOH was the microwave absorber. Furthermore, a large amount of aromatics were present in the bio-oil obtained using carbon as the microwave absorber.

The synthesis of a bipyridine poly(lactic acid) carboxylic end-capped macroligand coordinated to a platinum center was reported. The reaction between the metal ion and the polymeric ligand was run in a very efficient way through a one-step synthesis and the complex was tested for selective hydrogenation of α,β-carbonyl compounds. High selectivity was proven for double bond hydrogenation of 2-cyclohexen-1-one (up to 99%) and the production of 1-butanol from (E)-but-2-enal. Moreover, the catalytic system was still active after three catalytic cycles.

Microwave Assisted Pyrolysis (MAP) of the plastic fraction of Waste from Electric and Electronic Equipment (WEEE) from end-life computers was run with different absorbers and set-ups in a multimode batch reactor. A large amount of various different liquid fractions (up to 76.6wt%) were formed together with a remarkable reduction of the solid residue (up to 14.2wt%). The liquid fractions were characterized using the following different techniques: FT-IR ATR, H NMR and a quantitative GC-MS analysis. The liquid fractions showed low density and viscosity, together with a high concentration of useful chemicals such as styrene (up to 117.7mg/mL), xylenes (up to 25.6mg/mL for p-xylene) whereas halogenated compounds were absent or present in a very low amounts.

A comparative evaluation of traditional and innovative coatings for outdoor bronze surfaces was carried out, including blending or pre-treatment with non-toxic corrosion inhibitors on bare and patinated bronze surfaces to simulate both as cast and aged surfaces. Coatings recently applied in bronze conservation practice, commercially available coatings and an innovative end-capped poly(lactic acid) with a benzotriazole (BTA) moiety have been tested, as well as a triple-layer system (wax/acrylic polymer/wax). BTA, single-layer Soter wax, and double layer Incral44/Soter wax were used as a reference. The products were evaluated in terms of aesthetic features, molecular structure, and corrosion protection by means of colorimetric, spectroscopic, and electrochemical tests. All inhibitors showed similar or significantly better results compared to BTA. In particular, sodium oleate and tolyltriazole could be considered as promising lower-toxicity alternatives to BTA, while the triple-layer coating applied without pre-filming inhibitors proved to give a very high protection against corrosion. © 2017 Wiley Periodicals, Inc.

Palladium nanoparticles, generated by hydrogen reduction of Pd acetate, coordinated to a stereocomplexed 2,2′-bipyridine end-functionalized poly(lactic acid)-poly(ε-caprolactone) copolymer showed enhanced catalytic activity and chemoselectivity for the partial reduction of phenylacetylene compared to the reference system which did not contain the poly(ε-caprolactone). The obtained heterogeneous catalyst proved to be recyclable and suitable for selective phenylacetylene hydrogenation to styrene in solution and under solventless conditions.

A new and simple protocol for quantitative analysis of bio-oils using gas-chromatography/mass spectrometry is suggested. Compounds were identified via their mass spectra, and then unavailable response factors were calculated with respect to diphenyl as the internal standard using a modified method previously suggested for gas chromatography with flame ionization detection. This new protocol was applied to the characterization of bio-oils obtained from the pyrolysis of woods of different sources or using different pyrolysis procedures. This protocol allowed evaluation of the yields of products from poplar pyrolysis (among 50% and 99%), while a reduced amounts of products were identified from the pyrolysis of cellulose (between 46% and 58%). The main product was always acetic acid, but it was formed in very large yields from poplar while lower yields were obtained from cellulose.

Stump-roots and leaves from different residues of short rotation coppice (SRC) of poplar clones were transformed with microwave assisted pyrolysis to produce bio-oils. These products were obtained with high yield (up to 32.0%) and small water percentage (up to 17.5%), showed low density and viscosity and were fluid at room temperature. Bio-oils were characterized with several analytical techniques: 1H NMR, IR-ATR, and an original and a quantitative GC–MS method. Acetic and formic acids, acetic anhydride, furanes and various phenols were identified and quantified; among bio-oils a sample with high acetic acid concentration (543.3 mg/mL) was obtained. These techniques let to make possible a detailed study on the bio-oils to define a correlation between their chemical and rheological properties with the clones employed and parameters of the process.

Aromatic triblock polymers were synthesized, characterized, and tested as protective coatings for stone surfaces. Syntheses were carried out by a ring opening polymerization process from specifically synthesized monomers ((3S)-6-methyl-3-phenyl-1,4-dioxan-2,5-dione or 1,4-benzodioxepin-3-methyl-2,5-dione) and a perfluoropolyether diol (Fluorolink D10-H), as chain initiator. Polymers were characterized through spectroscopic and analytical techniques while their stability under photo-oxidative conditions was tested using a Solar Box. An excellent stability to environmental conditions was noticed with very low degradation during accelerated aging tests up to 1000 h, as detected by FTIR, molecular weight, DSC and weight loss. Furthermore, these polymers formed an excellent protective coating on the stone surface as shown by capillary water absorption test. Finally, as expected, very stable coatings were obtained as shown by aging tests. The stone surface showed negligible changes of color and a good hydrorepellency confirming a good durability of treatments. © 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016, 133, 43377.

The catalytic performance of small Pd-nanoparticles (NPs) (2.0 nm), partially covered by chemisorbed oxygen atoms, and of Pd-acetate, both stabilized by 2,2′-bipyridine-end functionalized poly(ethyleneglycol) monomethylether was compared in the selective hydration of nitriles to amide in water under mild reaction conditions (353 K). Regardless of the nitrile substrate employed, the Pd-NP-based catalyst showed much higher normalized TON-values (i.e. refereeing to the amount of surface Pd atoms) compared to the Pd(II) macrocomplex, as far as the first catalytic run was considered. Deactivation of the Pd-NP-based catalyst was significant due to the formation of a hydroxide-water layer on the NPs’ surface.
