“…Due to physically, chemically and biologically process the MPs secondary will be exposure, will be degraded become smaller pieces. These findings had similar pattern related due these fragments were resulted from break down, abrasion, and weathering of larger plastic products and are transported over the ocean (Jaini & Namboothri, 2022).…”

Microplastics (MPs) are discovered in various places even encroaching on marine protected areas (MPA). The aim of this research is to investigate the occurrences of MPs pollutant in MPA and non-MPA in Karimunjawa National Park (KNP). The results showed that MPs from sea surface water were higher in MPA than non-MPA with range as 47.89-106.20 items/L, dominated by fragment, 1-50 µm size, black color and HDPE, LDPE, PP, Nylon, PVC, ABS, and PET in polymer types. It induced since it supplied from it surrounding, specifically the south of MPA, whereas there have been cottage constructions generating many marine debris. These findings indicate that occurrence of MPs still dominantly influenced from anthropogenic activity. However, the hydrodynamic and MPs characteristic as well play an important role in MPs distributions.

“…In addition, the discarded epoxy resin components are difficult to reprocess and mine and are usually treated by incineration or burial, resulting in significant environmental pollution and resource waste. 8 Introducing dynamic covalent bonds (DCBs) into the epoxy cross-linked network is an effective means to solve the above problems. DCBs can undergo exchange reactions under certain stimuli.…”

Thermoset epoxy resin materials can be endowed with unique dynamic properties by introducing dynamic covalent bonds (DCB) into the cross‐link network of the epoxy resin. However, it remains a challenge to obtain epoxy materials with high mechanical, thermodynamic, and dynamic properties. In this work, a series of epoxy vitrimers with double DCBs were prepared by using a curing agent with imine bonds (PAMD) and an epoxy resin with disulfide bonds (BGPDS). PAMD and BGPDS are cross‐linked and form a uniform aromatic framework that ensures the mechanical and thermal properties of the material. High‐density DCBs ensure the dynamic performance of epoxy vitrimer. In addition, tetra‐needle‐like ZnO whiskers (T‐ZnOw) were added to the epoxy vitrimer for further reinforcement. The results demonstrated that epoxy vitrimer composites with T‐ZnOw content of 10 wt.% exhibit high tensile strength, high Tg, high healing efficiency, shape reconfiguration, reprocessing and rapid degradation. The degradation products can recycle and produce new epoxy vitrimer, leading to a closed‐loop recycling which reduced the environmental pollution and resource waste.

“…Sustainability is also increasingly becoming a crucial factor to consider when developing new coating materials to avoid the use of industrial processes and to decrease petroleum dependency [14][15][16][17][18][19]. Multilayer coating systems are often organic in nature, and each coating is composed of four main elements: a carrier, pigments, additives, and a binder [13,20].…”

“…Thus, the material needed for corrosion protection is significantly reduced, obtaining a more sustainable option that could not only improve the performance (corrosion protection and adhesion) but also reduce environmental concerns such as sea pollution caused by the release of microplastics. Indeed, a recent study reveals that particles from paint constitute more than half (58%) of all microplastics entering the world's oceans and waterways annually [15,16]. Therefore, hybrid coatings in which the organic part comes from renewable sources that can be used to replace thicker amounts of paints are an interesting sustainable option for marine corrosion protection.…”

To protect carbon steel from degradation via corrosion, it is usually coated using a multilayer system of paints composed of petroleum-based polymers. The chemical industry is currently moving towards more sustainable chemistry, in which one of the main objectives is to reduce fossil fuel use and the derived raw materials. However, the replacement of petroleum-based raw materials with those that are bio-based is not straightforward since the properties of these new materials are often inferior to the traditional ones. One of the most used resins in primer paints is Diglycidyl ether bisphenol A (DGEBA). This is an epoxy resin synthesized from bisphenol A (BPA), a toxic and carcinogenic petroleum-based compound. This study investigates the substitution of the primer coating in a three-layer coating system with two different types of primer coating formulations, one which is partially bio-based and another that is BPA-free. The corrosion protection effectiveness of these sustainable coatings is assessed not only at the laboratory scale but also in real offshore conditions. Moreover, the adhesion of the different coating systems is evaluated before and after each ageing test. The results reveal that these novel coatings exhibit comparable performance to conventional paints while providing a more sustainable corrosion protection alternative.
