A new approach that makes paper from straw, which cuts production costs and is kinder to the planet, is one step closer to reality thanks to an investment award of £90,500 from NESTA (the National Endowment for Science, Technology and the Arts) – the organisation that nurtures UK creativity and innovation.
The innovation is the brainchild of a Surrey-based environmental company, BioRegional MiniMills Ltd. The driving force behind this company is a former nurse, Sue Riddlestone who became very active in the environmental field after starting a family. Following a stint of voluntary work for the eco-lobby group Greenpeace, she co-founded BioRegional as an environmental charity. It works in partnership with industry to develop sustainable production and lifestyles through practical projects. The MiniMills offshoot was established in 1997 to develop new, cleaner technology to make paper on a small scale. Sue is joined by a range of experts from the paper processing industry.
There are reported to be nearly 9,000 paper and board mills worldwide, and the demand for paper is growing at a rate of 3% per annum. Current mills are huge operations run by multi-national companies. However, MiniMills’ new process would allow more independent paper makers to compete with these large-scale processes. Their method would facilitate the use of a much greater variety of raw materials, including straw - four million tonnes of straw goes unused in the UK annually - and wood from sustainably-managed, smaller woodlands for use in papermaking. This would provide income generation for both farmers and foresters.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
