This chapter summarises the literature concerning the nucleophilic addition of terminal alkynes to a varied scope of unsaturated electrophiles to prepare alkynylated molecules. Unlike classical methods that achieve this transformation by employing stoichiometric quantities of highly reactive metal acetylides and therefore require inert and anhydrous conditions, the transition metal-catalysed reactions described herein can be conducted in water, a benign and readily available solvent. In addition to overviewing transformations for the one-step addition of terminal alkynes to electrophiles, multi-component and tandem reactions are addressed. Furthermore, to offer a more complete resource for chemists seeking more sustainable routes to synthetic targets, a brief survey of the synthetic utility of the alkynylated reaction products is provided.

The (re)utilisation of silicon, silica and silicates is becoming highly important as there is a growing global need for renewable bioenergy, in the form of controlled biomass burning such as agricultural straws, wood pellets, grasses, etc. The anticipated growth in controlled biomass burning will generate significant quantities of ash often rich in silica and silicates. The valorisation of these waste materials is vital to ensure recovery and reuse of the inorganic species, in line with an elemental sustainability and biorefinery vision, and to add economic value in the form of biobased adhesives and coatings. This chapter discusses the market size and potential of silicas and silicates as binders and adhesives. A background to silica chemistry, its occurrence in biomass and its subsequent isolation from ashes is given. An in depth overview of silicon and silicates in adhesives is given, concluding with their potential role as replacements for traditional petroleum-based binders in particleboards.

Adhesives are not only being used increasingly in the design of medical devices, but also in the field of application, both directly on and in humans, for example as a replacement for the suturing and stapling of tissue through adhesive bonding. The advantages of using adhesives include less tissue damage, no incorporated materials that require removal, and a better biocompatibility. In this context, adhesives in the broader sense also perform functions that conventional methods cannot, for example as sealants or blood hemostats. In addition to fully synthetic and semi-synthetic adhesives, an increasing number of formulations are finding their way into research as well as clinical trials or clinical applications that are based on concepts taken from nature (biomimetic) or are a combination of biological and chemical components or are of completely biological origin. The importance of medical adhesives is evident not only in the almost double-digit annual growth rates, but also in the number of publications in this field. The constantly increasing requirements for the approval (CE marking in the EU, 510k or PMA in the USA) of new adhesives (fully synthetic, semi-synthetic, or biological) and the development of such systems in accordance with these requirements and those of the user (medical practitioners) still represent major challenges. This is partly due to the fact that development scenarios, such as the technology-push and market-pull approaches, are currently not being applied in a holistic and interdisciplinary manner.

The generation of functional materials from biomass waste streams represents an attractive and important topic in the context of developing future biorefineries. This chapter briefly summarizes our recent research on microwave-assisted low-temperature (<200 °C) pyrolysis of three biorenewable waste streams (i.e., spruce wood chips, waste office paper and DIR) for the generation of bio-oil, bio-char (microwave residue) and gas. The potential application of crude organic phase bio-oils as adhesives towards metal bonding was investigated. Furthermore, a model compound study using 5-(hydroxymethyl)-2-furaldehyde (HMF), catechol and levoglucosan was conducted to get further understanding of the adhesion properties of bio-oil towards aluminium bonding. We anticipate that these preliminary results will potentially lead to applications and provide new ideas for generating adhesives from currently underutilized biomass waste streams.

Adhesives are used in a variety of applications and have helped the development and growth of many industries. In the carpet tile industry, they are used to bind the fabric layer to the bitumen-backing layer. However, often, removal of such adhesives or separation of the layers can prove to be challenging and costly, with the simplest option being disposal. Therefore, redesign of the adhesive system used could prevent 1000s of tonnes of waste and valuable resources ending in landfill or incineration. There has been increased interest in ‘Smart’ or ‘switchable’ adhesives that can change bonding properties under certain stimuli, such as temperature, pH, pressure etc. This has been put into good effect in the carpet tile industry with the development of a modified starch adhesive that can switch bonding properties with steam.

Considering the importance of 1,3-propanediol (1,3-PDO, propane-1,3-diol, trimethylene glycol, 1,3-dihydroxypropane) as a platform molecule, as well as the exhaustion of fossil derivatives required for its chemical synthesis, glycerol, as a versatile and renewable feedstock, becomes a key enabler towards 1,3-PDO production. It has been a decade since major efforts were carried out in genetic engineering and bioprocessing aspects to improve the production titers and yield of 1,3-PDO. Subsequently, polytrimethylene terephthalate (PTT) was synthesized using 1,3-PDO, which has numerous polymer applications and became a competitor for commercialized polyethylene terephthalate (PET) and polybutylene terephthalate (PBT) polyesters. This chapter envisages a panorama of investigations on genetic aspects for improving the production of 1,3-PDO. Strategies to improve the synthesis of polyurethane and polyester from 1,3-PDO are also discussed. A detailed description of the genetics of dha regulan consisting of genes for 1,3-PDO production, along with the recent developments in genetic engineering strategies to improve the tolerance and production titers of 1,3-propanediol in individual genera, is explained. In focus with the applications of 1,3-PDO, the synthesis of various polyesters and polyurethane materials using polycondensation reactions is also described. Thus, the synthesis and properties of polyesters explained within offer valuable insights into future biomedical, pharmaceutical, and organ transplant applications.

Derived from powder coating of metals, pharmaceutical dry powder coatings have received great attention in the past ten years, owing to their striking potential to replace the organic solvent coating and aqueous coating used in the current pharmaceutical industry. After several initial trials of dry coating, electrostatic dry powder coating was developed and has attracted more attention due to its high coating efficiency and low overall cost. In this technology, coating powders containing coating polymers, pigments, and other excipients are directly sprayed onto the surface of the solid dosage forms without using any organic solvent or water. The deposited coating powders are cured to form a coating film. This dry powder coating technology has many advantages compared to organic solvent coating and aqueous coating. It eliminates the limitations caused by the organic solvent in solvent coating such as environmental issues and health problems. It also surpasses aqueous coating due to its shorter processing time and much greatly reduced energy consumption, leading to a lower overall cost. Specifically, electrostatic powder coating utilizes electrical attraction to promote the movement of coating powders towards the dosage forms, resulting in an enhanced coating powder adhesion, uniformity and coating efficiency, making it more promising compared to other dry coating technologies. This technology has already been developed and applied to various solid dosage forms successfully.

A higher legislative burden, resource scarcity and an increasing environmental awareness throughout the population have resulted in a growing demand for more sustainable products. This is also true for the printing industry. As a result, many printing ink manufacturers have shifted to more environmentally friendly inks. Thus, water-based and UV-curing systems have already started to replace solvent-based inks, which leads to a reduction of volatile organic compounds (VOCs) released during the printing processes. In addition, the use of bio-based monomers as building blocks for printing ink is further increasing. Besides the traditionally used vegetable oils, cellulose derivatives, and rosin, new bio-based compounds are being utilized in this field to replace petrochemical ink ingredients, such as polymeric binders, solvents, and additives. This chapter gives an overview of the developments in the field of printing inks derived from renewable materials, discusses advantages and drawbacks of the systems described and addresses problems unsolved so far.
