In this study, a solid acid was prepared by the sulfonation of surface modified α-zirconium phosphate (ZrP) single-layer nanosheets (SO3H@ZrP), and the prepared solid acid was investigated for the esterification of oleic acid with methanol to produce biodiesel. For comparison, liquid H2SO4 and commercial Amberlyst® 15 catalyst were also evaluated for the same reaction under the same conditions....

This paper presents a method for designing heat-reversible snap joints, locator-snap systems that detach non-destructively by heating a certain location of parts. It is expected to dramatically improve the recyclability of aluminium space frame (ASF) bodies by enabling clean separation of frames and body panels. Extending our previous work on the sequential design of the locators and heating ar...

Cross-linked resin-captured palladium (XL-QPPd) was readily prepared by simple physical adsorption onto the high loading QuadraPure macroporous resin and a subsequent reduction process. To enhance the mechanical stability, entrapped palladium nanocatalysts were cross-linked with succinyl chloride. Both transmission electron microscopy images and X-ray diffraction analysis revealed that the pall...

The goal of this paper is to present eco-innovation implementation in Poland and in some European countries. I assess factor influencing on ecoinnovation in small medium enterprises. Both current and expected energy and material prices are particularly important for pushing firms to reduce pollution, decrease hazardous substances and increase recyclability of products. Cost savings are an impor...

To address oil spillage and chemical leakage accidents, the development of efficient sorbent materials is of global importance for environment and water source protection. Here we report on a new type of carbon nanofiber (CNF) aerogels as efficient sorbents for oil uptake with high sorption capacity and excellent recyclability. Importantly, the oil uptake ability of the CNF aerogels can be main...

For preserving food packed in environmentally friendly and recyclable paperboard packages, it is important to have sufficient gas barrier performance of the container. Paperboard has poor intrinsic properties overcome this deficiency, so a coating needed that does not hinder recycling substrate. However, recyclability such coatings been rarely studied. Here, both removal an alkali-soluble resin...

The importance of product sustainability has become increasingly relevant, with several key stakeholders striving to improve the lifecycle environmental footprint their products in various aspects. This sense sustainable urgency also been felt cosmetic industry, which contributes significantly global plastic manufactured and used worldwide. Design for Recycling Reuse are two different approache...
