“…The addition of glycerol is dualpurposed: it works as a plasticizer and it improves the films' hygroscopicity (because of glycerol's three hydroxyl groups). [23] DMSO acts as a secondary dopant by stretching the PEDOT coils, therefore increasing the interchain interactions. [24] The resulting material conforms easily, sticks to most common surfaces, and is very resilient to deformations.…”

We report a flexible self-standing adhesive composite made from PEDOT:PSS and nanofibrillated cellulose. The material exhibits good combined mechanical and electrical characteristics (an elastic modulus of 4.4 MPa, and an electrical conductivity of 30 S cm −1 ). The inherent self-adhesiveness of the material enables it to be laminated and delaminated repeatedly to form and reconfigure devices and circuits. This modular property opens the door for a plethora of applications where reconfigurability and ease-of-manufacturing are of prime importance. We also demonstrate a paper composite with ionic conductivity and combine the two materials to construct electrochemical devices, namely transistors, capacitors and diodes with high values of transconductance, charge storage capacity and current rectification. We have further used these devices to construct digital circuits such as NOT, NAND and NOR logic. RECEIVED

“…Possible alternative solutions for the recycling of mineral wool waste include for example the utilization of mineral wool waste in cement-based composites [20] composite ceramics [21] or wood fiber composites [22]. A new solution for the recycling of mineral wool waste could be the utilization of the waste as filler in wood polymer composites.…”

“…A new solution for the recycling of mineral wool waste could be the utilization of the waste as filler in wood polymer composites. Its problem is that if the interfacial adhesion between the mineral wool fibers and polypropylene matrix can be improved, many of the mechanical properties could be improved as well [22]. This could be achieved via the addition of a different coupling agent or surface treatment of the mineral wool fibers.…”

Construction and demolition waste constitutes a huge part of the solid waste management system and is continuous on the rise because of the booming housing and building industry worldwide. Construction and demolition waste is not clear in its definition; it differs according to the location and type of the project which make it complicated to find a generic solution to construction and demolition waste management problems. A comprehensive list of construction and demolition waste stream was formulated and used in the course of this study. A thorough literature review was conducted to study the end life of each of the components of the construction and demolition waste stream and their reuse or recycling option. The conventional treatment of construction and demolition waste which is dumping them in landfills was presented and its negative impact on the environmental and socio-economic aspects and on sustainability highlighted making recycling the most viable option. The study aims at having a clearer picture of C & D waste classification methods, its components and their end of life treatment and evaluating them through the lenses of zero waste management. Zero waste is a way that promotes changing lifestyle and, ideologies to reach the ultimate goal of sustainable development through eliminating waste and having materials that circulate in closed loops. Applying zero waste concept to manage construction and demolition waste would be a great improvement in waste management as it promotes the reuse of resources, preserves the environment and is considered a step towards a sustainable environment.

“…Mineral additives have been used in wood-based panels manufacturing with success, primarily to achieve high mechanical strength, high thermal and sound insulation, or fire retardancy of wood-based panel products (Scheiding 2002, Mamiński et al 2011. Recently, the use of synthetic zeolite Y, modified with aminopropyl groups has also shown utility to reduce formaldehyde emissions from particleboards (Anonymous 2011).…”

The presented research is about the use of a new type of a functional inorganic additive in particleboards, for the purpose of reducing free formaldehyde releases. One-layered particleboards were prepared in the laboratory by mixing industrial wood particles and urea-formaldehyde resin. Natural, abundantly and cheaply available nano-mesoporous diatomaceous earth (DE) was used, without and in combination with urea as a scavenger. Silica quartz sand was also added as a nonporous analogy. Particleboards were pressed at two press factors (9 and 15 s/mm). Formaldehyde release was determined using the rapid 3-hour-flask method (DIN EN 717-3). As a result, DE additions insignificantly reduced bending properties of particleboards. Internal bonding was in part significantly lowered. The particleboard produced with 3% urea loaded on 5% DE prior to application almost halved (-45%) the formaldehyde release. Formaldehyde release was on the average 17% lower when pressed at 15 s/mm instead of 9 s/mm. By loading urea onto the nano-mesoporous structure of DE, an improved scavenging function of urea could be shown.
