In this review, we provide a bird's eye view of recent developments in the field of pressure-sensitive adhesives (PSAs) derived from renewable monomeric building blocks. This emerging research field has been driven by increasing sustainability requirements in the adhesive industry and bridges the gap existing between highly optimized petroleum-based synthetic PSA systems, which display superior performance but lack biobased content, and historical PSAs derived from naturally occurring biopolymers (e.g., starch and natural rubber), which provide more environmentally friendly bonding solutions but have inherent technical limitations that prevent their more widespread implementation in today's technically demanding applications. We critically reviewed a representative (and exhaustive) survey of recent synthetic approaches to the development of biobased PSAs from the academic (articles) and industrial (patents) literature categorized in two families: chain-growth and step-growth polymerization routes. Finally, we draw a parallel between renewable synthetic PSAs and nature's self-adhesive glues, highlighting how the synergy between green chemistry and biomimetic concepts could inspire the emergence of a new generation of smart, synthetic, biobased PSAs with differentiated properties that approach the ones that are found in the natural world and with a wide spectrum of potential applications in the industrial and medical sectors. © 2014 Wiley Periodicals, Inc.

The principles introduced by the Directive Concerning Integrated Pollution Prevention and Control (IPPC) (currently known as the Industrial Emissions Directive (2010/75/EU)) are innovative and have raised interests in the framework of the literature debate on environmental regulation. Many articles describe and analyze the application of the Directive in European countries, but only a few articles focus on how the interest for the Directive's principles, including the integrated approach, have reached countries outside the European Union. This paper aims to contribute to this topic, describing the experience of the authors in carrying out an EU-funded project on transferring the IPPC approach and Best Available Techniques (BAT) concepts to three Arab countries, i.e., Egypt, Morocco and Tunisia. The paper presents the experience referring to two sectors falling within the scope of the IPPC Directive: the textile and dairy sector. The objectives, methodologies, activities and experiences are described and can be used and valorized to integrate the IPPC approach and BAT concepts in the current environmental legislation of the three countries. © 2013 by the authors.

Patent
Vlaamse Instelling Voor Technologisch Onderzoek Nv Vito Nv | Date: 2012-10-26

The present invention relates to a detection device and a method for detecting a presence of an object in a surveillance area. The device comprises at least one infrared radiation sensing element each adapted for generating a sensor signal related to a quantity of infrared radiation received from within the surveillance area by the infrared radiation sensing element, a processing unit and an output means for outputting a determined presence of the object and/or a property derived therefrom. The processing unit is adapted for: obtaining the at least one sensor signal; generating at least one contrast value by comparing the at least one sensor signal to at least one reference value; determining the presence of the object by evaluating a condition on said at least one contrast value; and adjusting the at least one reference value such that negative feedback is applied to the at least one contrast value.
