Scientists develop paper that lifts viruses from water

While deceptively simple, this sheet is made from cellulose nanofibers and has a layered internal architecture designed to remove viruses from water, according to a news release from Uppsala University on May 18.

The paper filter improves upon other methods such as chemical disinfectants, which can produce toxic by-products. “Our goal is to develop a filter paper that can remove even the toughest viruses from water as easily as brewing coffee,” said Albert Mihranyan, who heads the study at Uppsala University. In 2014, the team had described a paper filter that removes larger viruses, and now researchers have their eye on refining the filter to remove smaller viruses.

UK Poll Finds Shoppers Prefer Paper-Based Packaging

The research revealed that over half of the 2,289 people surveyed in the nationwide poll, (some 57%) said they preferred their grocery and food packaging in paper-based material, whilst some 31% expressed no preference and just 8% preferred plastic containers. The consumers surveyed were also asked how likely they were to purchase a product from a retailer using paper-based containers as opposed to plastic containers. Some 46% said they were more likely to purchase an item if the packaging was paper-based, compared to 47% who said it would make no difference.

Swedish forest industry develops tomorrow’s sustainable forest machine

A new type of forest machine is currently driving around the forests of Sweden. It combines a low-impact approach, increased productivity and an improved operator environment and is the result of a major cooperative project that has been under way since 2019. The concept machine is called Centipede and it has been developed by SCA, seven other Swedish forestry companies and the forest machinery manufacturer Komatsu. The machine is currently being test driven and the results are promising. Swedish forestry is facing major challenges and the issue of sustainability is the focus of attention. For this reason, Södra, Sveaskog, SCA, Holmen, Norra Skog, Mellanskog, Stora Enso and BillerudKorsnäs, as well as the forest machinery manufacturer Komatsu Forest, have jointly developed a new forest machine for low-impact forestry. With its innovative technology, the machine – called Centipede – is designed to ensure the most sustainable possible management of forests for both the environment and people.

How to Participate in PEFC’s Standards Revision

As we begin our standard revision process 2016-2017, there are several different ways for stakeholders to get involved.

Expert Forum: The deliberations of the Working Groups will be informed by two online Expert Forums for Sustainable Forest Management and for Chain of Custody. People with expertise in these two areas can apply for membership. Stakeholder Conference: In spring 2017, we will organize 2-3 Stakeholder Conferences in different geographic regions. Public Consultation: Global Public Consultations will allow stakeholders anywhere in the world to provide input into the Enquiry Drafts of the standard, for a minimum period of 60 days. Revision Newsletter: We have created a new Standards Revision Newsletter with specific information about the revision process.
