Deinking is an important part of paper recycling that involves the removal ink particles from fibres. This industrial process so fibres can be recirculated back into production, which enables better sustainability as fewer fresh are needed. In this study, we examined five different alternative fibre materials agricultural residues and processes for pilot production papers. Papers containing invasive plants (Japanese knotweed), dedicated crops (miscanthus, acacia), (tomato stems), waste (jute...

Sustainability demands circular and material solutions with an emphasis on using local resources. Using alternative fibers from invasive plants agro-residue promotes production in smaller paper mills, which have additional benefits for the environment (protecting species, reducing agro-industrial waste). In electrophotography printing, toner adhesion is a vital quality parameter showing prints' resistance against different mechanical stress, leading to particle detachment. This study tested...

The use of an alternative fibre source for papermaking encourages more circular material streams with a focus on local harvesting and lesser demand large-scale pulping.The changes in the printing industry advent digital technologies, such as electrophotography ink-jet, that paper should have appropriate printability.Digital printability depends machine, toner paper.In this study, we tested six different papers made from invasive plants, namely, Japanese knotweed, black locust, Canadian...

The deinking of paper-based printed electronics is a growing concern regarding the increase products. benefits using substrates instead polymer or ceramic for single-use electrodes can contribute to sustainability goals. use invasive plant species making paper unique opportunity have several environmental benefits. In this study, recycling issue these products through technique was evaluated. Screen-printed on an plant-based and commercial cardboard were deinked, their optical,...

Ultra-high frequency radio identification tag antennas were screen printed directly onto pharmaceutical packaging and a comparison between commercially available inlays (hereafter reference tags) using two different inks tags A B) was made. The research revealed that the properties of slightly better than those for B on empty boxes. Nevertheless, all samples can be successfully read lengths up to 105 125 cm horizontally vertically oriented tags, respectively. None compared when placed in...

The use of screen-printed electrodes in different monitoring applications, e.g., polluted water, biotechnology, agriculture, industrial process control, and other are continuously being developed. New cheap open-source potentiostats have been recently emerging, addition to the commercial proprietary solutions on market. In this study, paper-based, were utilised as an alternative solution for ceramic-based tested with two (proprietary low-cost running wireless 64 bit Linux system installed...

Disposable screen printed electrodes are widely used for environmental monitoring such as water quality test, heavy metals detection and gas pollutants.(Hayat et al, 2014;Li 2012) Screen electrochemical consist of three electrodes: auxiliary, working reference electrode.The electrode is the principal on which reactions performed, while auxiliary to complete electronic circuit.(Hayat 2014) To produce efficient modification surface or altering geometry can be done.Researchers mostly modify...

Cardboard packaging is a good example of sustainable material use, yet even more solutions are available, such as replacing wood fibers with those from alternative sources like agricultural waste. In our research, we produced paperboard obtained waste tomato stems using pilot paper machine, and its basic, surface, mechanical properties were then determined. Additionally, corrugated cardboard the fiber-based analyzed performance under different environmental conditions. A comparative analysis...

The main objective of this research was the production and characterization bio-based indicators for pH-controlled smart packaging. Since pH-sensitive can change color depending on freshness or spoilage food, they be used to monitor level safety food products. Potato maize starch without with addition bacterial nanocellulose (BNC) were as a polymer matrix immobilization indicators. natural pigment anthocyanin, extracted from peels red onions, pH-sensing element. In addition, an ultrasound...

"One of the main purposes packaging materials is to protect packed object from mechanical damage that can happen during transport, storage or handling.
