…However, regulatory red tape for wood preservatives has limited access to some products in Canada, putting Canadian companies and users at a disadvantage compared to their counterparts in the United States. …Currently, creosote is the only registered oilborne wood preservative in Canada. Pentachlorophenol (Penta), another oilborne preservative historically used for utility poles, crossarms, and timber bridges, was phased out of use when the sole manufacturer ceased production. …There is a strong harmonization between Canada and the United States regarding standards for pressure treated wood, ensuring consistency across both countries. However, the United States faces fewer challenges than Canada in terms of oilborne wood preservatives, as there are several registered options available to U.S. end-users… Wood Preservation Canada is calling for a collaborative effort among industry leaders, regulators, and policymakers to ensure that safe, effective, and sustainable wood preservative solutions remain available for the infrastructure Canadians rely on every day.

Packaging is going back to its roots. Long before the advent of plastics, before the rise of mass production and the widespread adoption of synthetic materials, early civilisations relied on what the natural world had to offer – pressed bark, woven plant fibres, and rudimentary pulps – to store and transport food and goods. Paper, in particular, has long served as a trusted material for containment and communication alike. Today, that ancient material is undergoing a resurgence and is evolving to not only meet contemporary functional needs but also to respond to an urgent call for environmental responsibility. The rapid shift away from single-use plastic has created new momentum behind paper-based alternatives. From luxury goods wrapped in soft textured, bespoke papers to barrier coated containers engineered for performance and recyclability, fibre-based packaging is no longer confined to brown boxes or rustic aesthetics. It is becoming more refined, more versatile, and, crucially, more sustainable – at least on the surface.
The new Cowichan District Hospital will be British Columbia’s first fossil fuel-free hospital, Island Health announced on Earth Day, April 22. The new hospital is under construction on Bell McKinnon Road near Duncan on Vancouver Island and is scheduled to open in 2027. It is also Canada’s first hospital to achieve Zero Carbon Building – Design certification from the Canada Green Building Council. “We’re building hospitals that will care for people in our communities for generations,” said Bowinn Ma, B.C.’s minister of Infrastructure. “This certification shows that through innovative design, we can create hospitals that support the well-being of families and a sustainable future.”.. The hospital’s leading-edge sustainability measures will free up resources for patient care while supporting patient and staff well-being and delivering environmental benefits.
The new La Pêche Town Hall, built on a promontory facing Route Principale, is a mass timber, highly energy-efficient building that will soon become the first Passive House-certified institutional building in Quebec. Rectangular in shape and located on an east-west axis, the building, by BGLA architecture + urban design, features a long façade which faces directly south onto the main road. This façade offers views of the hills of Gatineau Park from the inside, while also using natural solar gain to serve as the building’s primary heating source. The presence of wood is felt inside and outside the project. Eastern cedar cladding envelops all the façades, while the glulam and cross-laminated timber structure is exposed and highlighted in each of the interior spaces.
The adage that one person’s waste is another’s treasure was proved true on Wednesday, May 21, when the province announced millions in investments in forestry biomass. Forestry biomass refers to forestry by-products that are not used in traditional wood-processing industries like sawing, veneering and pulp and paper. Examples include: crowns, branches, bark, sawdust, wood shavings, and wood chips. It is used in everything from food additives to building materials. It also has many emerging uses, including renewable natural gas, bioplastics and hydrogen, considered to be responsible alternatives to carbon-intensive products. The government says their aim is to protect workers and jobs in the forestry sector… The program has invested up to $20 million each year in projects to increase wood harvest, create forest sector opportunity and find new uses for wood in collaboration with stakeholders, industry and Indigenous communities.

The American military is looking at the possibility of using 3D printing, additive construction methods and cross-laminated timber (CLT) to build new military barracks and other buildings at various bases. The U.S. Army Corps of Engineers has already built new barracks at Fort Bliss, Texas, using 3D printing. …CLT is also being used in another centre planned at Joint Expeditionary Base Little Creek-Fort Story, also in Virginia. …Engineers at the Air Force Civil Engineer Center of the Air Force Installation and Mission Support Center are leading the way with research and development on the possibility of implementing concrete building construction techniques in future military construction projects. They discussed a number of topics, including additive construction, 3D-printed buildings, high performance cement and concrete mixes, geosynthetics, mass timber, composite materials, industrialized construction, tension fabric structures and carbon fiber-reinforced polymers.
The American Wood Council (AWC) has released a national Mass Timber Alternative Materials and Methods (AMM) Guide for use with the 2018 International Building Code (IBC). This new resource is designed to support building code officials as they review, permit and approve mass timber projects across the country. The AMM Guide is designed to help bridge the gap between the codes adopted in each state and the newer mass timber provisions in the 2024 IBC. Adopting the most recent edition of the Building Code, like the 2024 IBC, can be a slow multi-year process for states or jurisdictions. As a result, there is sometimes a gap between what is included in the currently adopted code in a state and what is allowable based on the latest available ICC I-codes. The AMM guide serves to fill that space by offering code provisions for jurisdictions without mass timber specific guidance.
PORTLAND, Oregon – The Port of Portland is leasing a former marine terminal to a mass timber company as part of an effort to spur housing development and job growth in the area. On Wednesday, the Port of Portland approved a lease for Zaugg Timber Solutions to open a factory at the Port’s Mass Timber and Housing Innovation Campus at Terminal 2. …“Our partnership with ZTS marks a major leap forward in developing the Mass Timber and Housing Innovation Campus at T2,” said Kimberly Branam. “Their new manufacturing facility will boost our region’s economy by promoting sustainable forestry practices, creating quality jobs, and increasing housing production.” While the new 100,000-square-foot manufacturing facility is expected to open in 2028, ZTS will produce mass timber modular housing units, industrial and commercial buildings and other building components starting in 2026 in an interim manufacturing facility at the terminal, officials noted.
After this year’s fires burned through the Palisades and Altadena neighborhoods, destroying over 16,000 structures, the city is reckoning with 4.5 million tons of debris, according to LAist—”the largest municipal wildfire cleanup operation in recent history.” As a result, the Army Corps of Engineers is sending trucks to 18 different regional facilities including landfills and recycling plants to manage the process of clearing out build remnants and remediating hazardous materials. Trees that appear damaged or unviable are cut down and sent to a local golf course to be mulched—a fact that doesn’t sit right with local sawmill owner Jeff Perry. In the aftermath of the Palisades and Eaton Fires, Perry teamed up with local landscape architects to create Altadena Reciprocity, an initiative that helps homeowners recycle an often-overlooked resource—neighborhood trees—into a product that residents can use for flooring, stair treads, door casings, and much more. 
Pulp and paper company Green Bay Packaging will be breaking ground on a $1 billion expansion to its Morrilton packaging plant Tuesday, according to a news release from Gov. Sarah Huckabee Sanders’ office. The company announced an expansion of its Arkansas Kraft Mill in Morrilton in December. The news release from Sanders’ office lauded the investment as the “largest capital investment project in Central Arkansas’ history.” It comes about a month after the announcement of a $1 billion data center in Little Rock, which was referred to as the “largest economic development capital investment” in Little Rock’s history. Green Bay’s multi-year expansion is geared toward modernization. According to a release, it will “significantly enhance the infrastructure of the mill” and, among other investments, it will involve the installation of an electric turbine generator, which will “substantially reduce” the plant’s Scope One and Scope Two greenhouse gas emissions.
Mass timber continues to gain traction in the United States for its sustainability, strength and aesthetic appeal. …In just the last four years, Texas saw a 168% increase in the amount of mass timber projects either in design, construction or completed. As mass timber developments in Texas increase in popularity, owners and contractors face a critical decision: whether to source the material domestically or internationally. The decision isn’t as simple as price — although it is a big factor. There are other points to consider when selecting your mass timber provider. …With threats of tariffs and rising material costs, builders might feel inclined to source mass timber from domestic providers. According to Forisk, an industry research and consulting firm, there are 38 mass timber production facilities across the United States and Canada —24 of which can produce cross-laminated timber (CLT). Nearly 51% of those facilities are located in the Northwest region of the United States.
Mass timber construction is gaining traction for its sustainability and efficiency, yet it brings distinct insurance and risk management challenges that require industry collaboration and proactive strategies. Key Takeaways from this Article:
Maximising the use of bio-based products is key to meeting current sustainability targets. Yet according to sustainability consultancy Metabolic, using bio-based products for half of new housing in Europe would require production of engineered timber to increase nearly fivefold, and roundwood by four and a half times. Given the improbability of an uplift in production on that scale, as well as the current rapid growth in global demand and the UK’s own limited timber harvest, using the country’s waste timber to make ‘cross-laminated secondary timber’ – CLST – would seem to make a great deal of sense. Rather than its current fates of combustion for energy recovery, chipping for MDF, dumping in landfill, and other low-grade, non-circular activities, incorporating this plentiful material into supply chains would benefit the construction industry, as well as the country’s economy and environment. And it would also seem to be a highly achievable ambition – so why isn’t it happening?
EDINBURGH, SCOTLAND — The International Sustainable Forestry Coalition (ISFC) welcomes the release by the International Organization for Standardization (ISO) of its new Standard covering the way greenhouse gas accounting should be applied to wood and wood-based products. Until the publication of this Standard, there had not been an internationally agreed upon accounting approach for biogenic carbon emissions and removals – an important piece of the puzzle to support corporate climate action and reach global net zero targets. The new series is ISO 13391 Wood and wood-based products — Greenhouse gas dynamics, and covers all essential components of carbon accounting for the sector: carbon in forests, carbon in harvested wood products and potential greenhouse gas emissions avoided through the use of wood-based products instead of fossil-based products.
The legacy sewing pattern brands Simplicity, Butterick, McCalls, and Vogue, commonly referred to as the Big 4, have been sold to a liquidator. 
Global efforts to curb greenhouse gas (GHG) emissions are accelerating across industries, and the construction sector is no exception. With buildings responsible for a significant portion of global emissions, sustainable alternatives have come under intense scrutiny. Cross-laminated timber (CLT) has emerged as a promising substitute that not only reduces the carbon footprint associated with conventional materials like steel and concrete, but also contributes to long-term carbon storage. However, as CLT gains traction in mid- and high-rise construction, its full environmental impact—both positive and negative—must be understood. In a recent study, researchers combined economic modeling with a cradle-to-grave life-cycle assessment (LCA) to capture the comprehensive climate mitigation potential of CLT. This interdisciplinary framework was designed to quantify both the direct emissions benefits of material substitution and the broader market and ecological reactions that come into play when CLT adoption accelerates.
…Mass timber provides several key learnings to understand how bioregional design can be developed and scaled. In the early 1990s, cross-laminated timber was invented in Austria, primarily driven by efforts to add value to softwood timber. The process involves glueing layered boards together to create strong, stable panels. Canada was an early adopter in North America, supported by knowledge-sharing with Europe and government-funded projects like the Wood Innovation and Design Centre in British Columbia. The US followed with key projects such as the Framework Building in Portland and T3 in Minneapolis, demonstrating that mass timber is viable for mid-rise and even high-rise buildings. The Canadian National Building Code was updated in 2020 and the American International Building Code was updated in 2021 to allow mass timber buildings up to 18 stories in certain conditions based on these pilot projects.
As the popularity of wood-based materials in building construction increases, facade-based applications are becoming more desirable and prevalent. Wood’s susceptibility to decay is a familiar phenomenon, and many established preservation methods exist. However, most wood treatments for external use are problematic from human health and environmental perspectives. Conventional preservation chemicals …contain known hazards. …For these reasons, scientists and manufacturers have been developing alternative techniques that are biocompatible and ecologically friendly, aiming to preserve wood effectively without the drawbacks of harmful chemicals. An established example is acetylation, a process that chemically alters wood to make it water resistant without toxic substances. …A Florida Atlantic University research team has developed a method to elevate the mechanical performance of hardwood as well. The technique strengthens the cell walls of trees by introducing an iron compound into their vascular systems. …Other investigations seek to prevent decay before it begins.
