Canada has legislated the mandatory adoption of paper straws just in time for new evidence to emerge that the new straws may be just as unsustainable as their plastic predecessors. A new study published in the journal Food Additives and Contaminants examined more than 20 different brands of plant-based straws and found high levels of toxic chemicals in almost all of them. “These ‘eco-friendly’ plant-based straws are not necessarily a more sustainable alternative to plastic straws,” concluded a research team based at Belgium’s University of Antwerp. Straws examined by the researchers were largely found to be laden with per-and polyfluoroalkyl substances (PFAS), commonly known as “forever chemicals.” …The University of Antwerp team performed chemical analysis on 39 different types of straws sourced from Belgian supermarkets and fast food outlets: 20 paper, five glass, five bamboo, five stainless steel, and four plastic. Only the stainless-steel straws were found to be completely PFAS-free.

Text on a box of doughnuts caught my eye – it read: “This window is recyclable, repulpable and plastic-free.” …What I eventually found out is that the term “plastic-free” isn’t nearly as simple or self-explanatory as it sounds, and that making single-use packaging greener is a complex challenge for everyone involved. …And apparently two years ago, A Plastic Planet stopped certifying bioplastic as plastic-free. …Laura Parlagreco, Astro Box’s vice-president of operations, said the window was made of cellulose acetate from wood pulp “sustainably sourced from fast-growing eucalyptus trees.” …As a confusing array of bioplastics hit the market, A Plastic Planet raised its standards and no longer thought bioplastics met the bar for being “plastic-free.” The group worried that the certification could be used to greenwash products that didn’t break down into nutrients for nature.

Massive Canada Building Systems, a Port Moody, B.C.-based mass timber and modular building manufacturer… has secured a contract to design and build a single-level underground parkade of mass timber on a 1.3-acre parcel of property in Gibsons, BC. It will be the first-ever underground mass timber parkade in Canada. “The idea of a mass timber parkade is to reduce the amount of concrete and the heavy carbon footprint of cement and steel,” says CEO Gaetan Royer. “Only the perimeter of the parkade and its foundation will be concrete. All interior posts and beams will be mass timber. The top of the parkade will be covered with cross-laminated timber panels. A roofing surface will make the entire podium waterproof.” …The roof of the parkade, supported by band beams over wooden posts, will be the base for a six-storey mass timber apartment building, containing 109 rental housing units and 14 two-storey townhomes.

Brent Comber may not have taken a direct path to his woodworking practice, but since the beginning of his winding design career, his native Pacific Northwest landscape has been a constant variable in all that he does. About four decades ago, Comber’s career began in garden design. …In the first few years of his garden design practice, Comber continually came up against a shortage of options to furnish these outdoor spaces in line with his aesthetic vision. …Comber has always been handy, and as he learned the woodworking techniques necessary for his growing furniture design practice, a great deal of the process was trial and error. …And around 2008, Comber’s garden design business was phased out, and art and design became the sole focus. Comber’s wooden furnishings possess a raw, elemental feeling that comes from the simplicity of form and the prominence of his chosen material—reclaimed wood from local Vancouver sources.

Microplastics have been found in more than 99% of tap water samples in Canada, the US and Europe — along with every single water body from the Antarctic to the North Pole. And 10 billion tonnes of it will have accumulated in the environment by 2025. The University of British Columbia’s BioProducts Institute has unlocked what they believe is a silver bullet solution to removing it almost entirely, using waste from sawmills. Scientists found that adding tannins … to a layer of wood dust, it can create a filter that traps virtually all microplastic particles present in water. “Our filter, unlike plastic filters, does not contribute to further pollution as it uses renewable and biodegradable materials: tannic acids from plants, bark, wood and leaves, and wood sawdust—a forestry byproduct that is both widely available and renewable,” said Dr. Orlando Rojas, the institute’s scientific director.

LANGFORD, BC — An elementary school under construction in Langford is drawing inspiration from another sort of structure — a tree house. Going in that direction came out of the need to deal with the vertical focus of the building design, said architect Lindsey Salter. “The school is four storeys total.” …The stacking effect, with the school tucked into the forested area behind it and offering sweeping views, leads to the tree-house comparison. …The $39.6-million school will be about 45,000 square feet and accommodate 480 kindergarten-Grade 5 students in 20 classrooms. It is due to open in September 2025, and will feature a neighbourhood learning centre and child-care spaces. …The use of mass-timber construction is a big part of that, she said, as is the use of heat pumps and solar power. Going in that direction is “embedded into the funding from the province,” Salter said.

It’s official. On Sept. 4, the Liquor Control Board of Ontario will give away its last paper bag. Fifteen years after the country’s largest liquor retailer dropped the axe on plastic bags, the time has come to say goodbye to their paper cousins. It’s about time, right? The initiative, according to the LCBO, will eliminate the use of nearly 135 million bags every year, saving the equivalent of more than 188,000 trees and diverting 2,665 tonnes from landfill. There’s only one problem… The numbers don’t add up. And aren’t paper bags supposed to be made from recycled paper? Most paper is indeed made from recycled material. …Then there is the claim that this initiative will divert 2,665 tonnes of waste from landfill. This is just plain false. ..In place of paper bags, LCBO customers can request an eight-pack carrier made out — I’m not making this up — cardboard, which is to say, trees.

When It Comes to Packaging, What’s Actually Sustainable?

Region: Canada, Canada East

EACH YEAR, Canadians throw away the equivalent of 300,000 garbage trucks of plastic waste. But only 9 percent of that gets recycled. Many of the items we’ve grown to rely on every day—Tim Hortons coffee cups, grocery-store bags, takeout cutlery—have ended up in landfills or, worse, in our rivers and lakes. In an attempt to achieve zero plastic waste by 2030, Canada has banned the use of these products, with retailers swapping single-use items for seemingly more sustainable alternatives. But in the months since the regulations were first enacted, environmentalists have expressed concerns over how the increased demand for paper could create an entirely new problem by putting more pressure on Canada’s forests. Is the federal government’s strategy actually working? To find out, we spoke with Toronto Metropolitan University’s Natalia Lumby, whose research focuses on sustainable packaging.

TORONTO – Limberlost Place, Ontario’s first mass-timber, net-zero carbon emissions institutional building, has now reached the highest point in construction. The final wood and steel beams were installed in the 10-storey facility located at George Brown College’s (GBC) Waterfront campus in Toronto’s growing east Bayfront community. Limberlost Place’s structure was completed using an intricate installation method including a sequence where each mass timber column and cross-laminated slab band would be placed. The structure includes three, three-storey mass timber columns which are amongst some of the largest in North America. Topping off signifies a shift in focus to completing the exterior envelope, starting the interior fit-up (including the installation of other mass timber pieces such as the learning landscape feature stairs), and commissioning the building.

Last fall, the specialty paper maker Dunn Paper closed its mill in Port Huron, Michigan. …In March, the packing paper firm Sonoco announced it would permanently shutter its Hutchinson Paper Mill. …At first glance, the closure of America’s mills might make intuitive sense. Personal computers and the internet were supposed to obviate the need for a lot of paper. And in many ways, they did. As a result, annual worldwide production of printing and writing papers has declined by about 30 percent since its high in 2007. But that’s not quite why American paper mills, overall, are closing. Many of the mills closing in the U.S. don’t make this kind of paper, and the diminishing relevance of printer paper hasn’t spelled the end of Big Paper, anyway. Annual production of paper and paperboard has grown by about 60 percent since 1993. …The real game changer was the entry of China into the World Trade Organization in 2001.

A new report from the National Academies of Sciences, Engineering, and Medicine has backed a 2022 U.S. Environmental Protection Agency draft toxicological risk assessment review that found formaldehyde to be a human carcinogen linked to cancers such as leukemia. The Aug. 9 report was challenged by the American Chemistry Council (ACC) that claimed numerous flaws with the EPA’s review process and the report from NASEM. “Overall, the report finds that EPA’s draft assessment follows the advice of prior National Academies reports and that the agency’s findings on hazard and quantitative risk are supported by the evidence identified in the document. The report recommends that EPA revise the document to ensure that users can find and follow the methods used in each step of its assessment for each health outcome. The study — undertaken by the Committee on the Review of EPA’s 2022 Draft Formaldehyde Assessment — was sponsored by the U.S. Environmental Protection Agency.

CLT (cross-laminated timber) is a buzzword these days. …Regardless of CLT’s seemingly recent popularity, the technology itself is a century old, and just celebrated its 100th birthday this August. And despite general consensus that CLT was invented in the 1990s in Europe, the technology was in fact first conceived in the good ole U.S.A. On March 17, 1920, two residents of Tacoma, Washington, Frank J. Wars and Robert L. Watts, filed a patent application for a “new and useful improvement in Composite Lumber.” The application by Wars and Watts stated: “The strips or boards thus formed are then cut into suitable lengths and such lengths are then superimposed one above the other so as to form a plurality of layers, with the grain of the wood in one layer running at an angle to the grain of the wood in the adjacent layer.” The patent application by Watts and Wars was approved on August 21, 1923.

Wood has now re-entered the tall building discussion as one of many materials available to the design community. Its many attributes ensure a greater role in buildings of all kinds going forward.” Nearly seven years later, this update report (2023) summarizes policy and code changes which have occurred in recent years and the trends in adoption of mass timber. We also look ahead to consider the challenges that mass timber may face. This report focuses on developments related to mass timber construction in the United States with some references to resources and information available globally.

Region: United States, US West

I recently read an article by CNN journalist Chris Isidore about the huge construction costs to rebuild Lahaina after the terribly destructive fire. He talked about the costs of lumber and labor being so much more than on the mainland. I would suggest a much better alternative to just rebuilding 2,000 homes in timber, which would be at risk of fire. There now are much more modern but proven building systems called insulated concrete forms. Essentially you use a LEGO-like block form work to hold concrete in place while it sets up. This form work is made of a fire-resistant foam that acts as an excellent insulator against heat (or cold). …The biggest obstacle to overcome in Oahu is the hold that the timber suppliers have on the local construction industry. Maybe a hot potato, but surely somebody has to think outside the box and not just rebuild with timber again.

In 2010, the U.S. government announced a multi-billion-dollar plan to improve the energy efficiency of its buildings, including a focus on LEED certification. Used worldwide, LEED—Leadership in Energy and Environmental Design—is a system that rates buildings on energy efficiency. A new study examined the effects of LEED certification on energy efficiency in federal buildings. The study found no effect on average energy consumption, primarily because many other factors come into play when rating energy. The study was published as a working paper with the National Bureau of Economic Research (NBER). “Energy use is just one of a number of attributes that is scored under the LEED program,” explains Edson Severnini, who coauthored the study. “If energy efficiency is the primary goal, LEED certification may not be the most effective means to reach that goal.” The study found no effect of LEED certification on average energy consumption in federal buildings.

Along with forest managers, builders are key change agents of forest ecosystems’ structure and composition through the specification and use of wood products. New forest management approaches are being advocated to increase the resilience and adaptability of forests to climate change and other natural disturbances. Such approaches call for a diversification of our forests based on species’ functional traits that will dramatically change the harvested species composition, volume, and output of our forested landscapes. This calls for the wood-building industry to adapt its ways of operating. Accordingly, we expand the evaluation of the ecological resilience of forest ecosystems based on functional diversification to include a trait-based approach to building with wood. …This plant-building trait-based approach is conceived to reveal the changes in forest management and wood construction needed to develop more resilient forest ecosystems and wood construction industry in response to global change.

Category: Wood, Paper & Green Building
Region: International

The assumption that wood houses are not made to last is simply that: an assumption—and an incorrect one at that. The oldest wood building in the world is Japan’s Hōryū-ji pagoda, which has a cypress structure that is now more than 1,300 years old. In Norway, there is at least one wood house that researchers believe dates back to 1170 while another in Switzerland was built in 1176. And countless half-timbered houses based on a timber-rod structure are well over 400 years old. …Wood offers a whole range of advantages for climate-friendly architecture. Most notably, its net CO₂ output is significantly lower than that of many other building materials. …When a wood house reaches the end of its life, it has the advantage of being more easily recycled than steel or concrete.

The Marks and Spencer retail building in London might be saved from demolition thanks to rising support to retain buildings. But what are other leading countries doing? The UK government has blocked the demolition of the Marks and Spencer’s Oxford Street store in a move that looks to respond to the activist campaigners from within the built environment. …The movement is a campaign by the UK’s Architects’ Journal and historical building campaign group SAVE Britain’s Heritage, calling for priority in retrofitting existing buildings over demolition and rebuilding. …The Netherlands claims to be the first country to mandate life cycle assessments (LCAs) in 2013… Sweden followed suit in 2022, enacting the Act on Climate Declarations for New Buildings, which required developers to calculate the embodied carbon emissions for new buildings… France took it a step further calling for all new public buildings to be constructed from at least 50 per cent wood or other sustainable materials.

A new startup co-founded by Carlo Ratti says it could reduce waste in the manufacturing process of cross-laminated timber (CLT) by up to 30 percent using AI tech. Carlo Ratti, who is the founder of Carlo Ratti Associati and a professor at MIT, has launched a new startup called Maestro in collaboration with Mykola Murashko, a Cambridge graduate, to pursue the research, which it calls AI Timber. The basic idea is that instead of reducing irregular trees into uniform straight lines and therefore producing significant waste wood, AI Timber maintains the varied shapes of the trees. It uses a combination of AI and digital machining tools to first scan a set of raw timber logs. The logs are then flat sawed into irregular boards, suiting the size of the wood. From there, software is used to identify the ideal sequence to fit them together, like a puzzle piece, resulting in less overall waste.

Major Japanese paper manufacturers are developing a new wood fiber material that could help promote decarbonization and reduce the use of plastics. With demand for paper in the doldrums, the industry is looking to expand the use of wood, a renewable resource, beyond paper products. Domestic demand for paper and paperboard has been falling since its peak in 2000. …To overcome the situation, the companies are developing cellulose nanofibers, or CNF, seeing them as a promising next-generation material. CNF is a fine fiber with a diameter of nanometers, created by the loosening of wood fibers, or pulp, supplied from forests. It is light and strong, and has excellent elasticity. The addition of CNF can create high-strength materials and reduce the use of plastics. They are expected to be used in vehicles, home electric appliances and building materials.

Region: International

Wood as a building material is a genuinely renewable source that combines strength, versatility and durability. Houses. Bridges. Furniture of all shapes and sizes. And bikes? Japanese designer Masateru Yasudu has created the Moccle, a single-speed bicycle made primarily of two bent plywood sheets layered with carbon fiber. These sheets form the top tube, down tube and rear stay – and there are two more used for the forks. …Yasuda says: “To make use of the flexibility of wood, the structure of the frame was designed with a large two-piece structure to avoid cutting of the wood fibers as much as possible. Eliminating large changes in the cross-sectional area shape, a smooth and beautiful shape was derived.” …The choice of wood and fiber differs depending on the rider’s weight. Each Moccle is a custom affair, with the geometry also tailored to fit the individual rider. It lists at 6000 euros for a custom build.

Architects have welcomed insurer Aviva’s decision to include engineered timber in commercial property developments. The company, one of the largest insurance firms in the UK, said it was increasing its underwriting capacity for schemes using products such as cross-laminated timber and glulam following a recent pilot. Insurers’ nervousness over timber in construction is regularly cited as one of the reasons concrete is not being replaced by more sustainable wood products. Some brokers were reportedly quoting teams up to 800 per cent more for insurance on schemes featuring engineered timber compared with traditionally built buildings. But Aviva has said it wants to ‘commit underwriting capability towards’ the development of more environmentally friendly construction. Its UK & Ireland General Insurance chief executive Adam Winslow said: ‘There are a growing number of developers looking to build more sustainably, both by using sustainable materials like engineered timber, and by adopting modern methods of construction.
