The recovery of fibres from waste paper (WP) and deinking sludge (DIS) reduces the stress on nature compared to collection virgin pulp for production. Moreover, if not recycled, WP DIS are mainly landfilled incinerated, being thus responsible release greenhouse gases (GHGs) into atmosphere. In this context, energy would contribute increasing independence improving management in industry. From a...

The objective of this work was to investigate the behaviour of some model surfactants used in the deinking process, namely, sodium oleate and two ethoxylated nonionic surfactants (C12E6 and C14E6) as well as to investigate the suitability of various model substrates for mimicking interactions in technical systems. The influence of the adsorption to the air – water interface has been measured by...

Sustainability is a premise that has been implemented in all technologies, industries, and service activities to have as little impact on the environment possible. Typography profession made its contribution by creating eco fonts. In each country, law regulates lifespan of storage everyday business documents. One ways reduce consumption ink, which can be achieved printing document with more sus...

Recycling and deinking processes cause fiber damage because of hornification phenomena and increased external fibrillation. Mechanical refining has been used for many years to enhance the mechanical properties of paper. Biorefining of pulp using enzymes is receiving increasing interest for energy reduction at the refining step of the papermaking process. Moreover, enzymes have also been used fo...

Rivers used for drinking water production might be subject to anthropogenic pollution discharge upstream of the intake point. This problem was investigated in the case of the Moselle River, used for water production in Nancy (350,000 inhabitants) and which might be impacted by industrial activities 60 km upstream. The arsenic flux of a pulp and paper mill discharging in the Moselle River at thi...

Xylanase is a major enzyme used in the paper and pulp industries for biobleaching applications. There are possibilities for xylanase with better properties suitable for industrial applications. This paper focused on a potential xylanolytic fungus, Trichoderma viride VKF-3, obtained from a mangrove soil sample. Optimum conditions for xylanase production were tested by culturing T. viride VKF3 un...
