HCM City (VNA) – Despite daunting challenges, Vietnam’s exports of wood and wooden furniture have shown signs of recovery since the end of 2023, Director of the Vietnam Chamber of Commerce and Industry (VCCI)’s Ho Chi Minh City Branch Tran Ngoc Liem said on February 26. At the opening ceremony of the Vietnam International Furniture & Home Accessories Fair 2024 in HCM City, Liem said that shipment of the products in December 2023 rose 10.3% month-on-month to 1.6 billion USD while that in January grew 10.2% from the previous month to nearly 1.8 billion USD. He said this was the only product in the field of agriculture with export value exceeding 1 billion USD within a month, and 32 out of 45 key export markets seeing growth. However, Liem said that the wood industry is facing several problems that affect its sustainability, including risks related to imported timber materials, the EU’s deforestation regulations and requirements for wooden products to have low carbon footprints.

Henkel and Covestro are cooperating to promote the sustainability of adhesives in timber construction. Covestro provides polyurethane-based materials based on bio-attributed raw materials, which are used by Henkel for high-performance adhesive solutions. The German chemical companies Henkel and Covestro are joining forces to promote the sustainability of adhesives in load-bearing timber construction. Such elements, such as cross-laminated timber or glulam, can be found in a variety of interior and exterior building applications, from stairs to facades and load-bearing components. For this purpose, Covestro Henkel provides polyurethane-based materials. These are based on bio-attributed raw materials that are assigned using mass balancing. Henkel then uses these for high-performance adhesive solutions.

While many people have an affinity for wood furniture and interior spaces, few of us realize the extent to which wood can tangibly affect our mental health and wellbeing. But according to a scientific study in the International Journal of Environmental Research and Public Health, this effect is measurable and significant. Fifty volunteers were observed in the wooden waiting room at the National Oncology Institute in Bratislava, Slovakia before and after their stays in the waiting room, via heart rate, respiration activity, and blood pressure. According to the study, the effects of spending time in the wooden waiting room were overwhelmingly positive. “The usage of wooden materials verifies their regenerative and positive impact on the nervous system, through the appealing aesthetics (color, texture, and structures), high contact comfort, pleasant smell, possibility to regulate air humidity, volatile organic compound emissions, and acoustic well-being in the space”.

Wood may be viewed as a more old-fashioned type of building material, but wood skyscrapers may actually be the buildings of the future. And now, one renowned Japanese construction company has recently completed a fully wood-framed tower near Tokyo, as Bloomberg reported. Obayashi Corp. completed Port Plus, a training and education facility in Yokohama using a technique called mass-timber construction, which uses thick, compressed layers of wood that create strong, structural load-bearing elements that rival materials like steel and concrete, according to the information platform naturally:wood. Unlike steel and concrete, though, wood is a much more planet-friendly building material. Per Bloomberg, Obayashi estimates that building Port Plus generated the equivalent of about 2,500 metric tons (more than 2,750 tons) of carbon dioxide, whereas making the same building out of steel would have resulted in 4,200 tons of carbon dioxide equivalent. The same building made out of concrete would have generated 8,600 tons.

BRAZIL — Mass timber is an innovative construction solution that is gaining prominence worldwide due to its sustainability and technological benefits. In 2020, the opening of the first Dengo concept store, located in São Paulo, marked the debut of the brand’s first interactive factory and the pioneering use of CLT in a high-rise building in Brazil. Developed by architecture firm Matheus Farah and Manoel Maia, the project faced several challenges precisely because of its use of this new technology, which was just beginning to emerge in the construction sector. The choice of CLT as the project’s main building material reflects a commitment to sustainability and to reducing its environmental impact, as it helps mitigate carbon in the atmosphere. In addition, its use allows for cleaner, lighter, and faster construction compared to traditional building methods. 

WorkStack, located off a busy road in Charlton, is one of a series of innovative timber buildings by dRMM across multiple sectors, exploring different structures at different scales. …The design answers a growing need for industrial capacity while challenging generic steel ‘tin shed’ light industrial architecture. Many London boroughs have reallocated industrial land, which inevitably becomes residential, forcing production away from city centres. …Built to be affordable to rent, operate and maintain, these workshops answer GEB’s brief to provide flexible, practical and inspirational workspace. …It is a cross-laminated timber structure, with limited steel, polycarbonate, glass and rubber introduced where required for functional purposes. Each building element is designed to be as efficient as possible – a legible, direct design without excess.

Henning Larsen has won a competition for the design of a campus building at CERN. Designed in collaboration with local architects Brière Architectes, the timber building and landscape are designed to be “immersed in nature, with biogenic materials and low-carbon design prioritized to generate community, collaboration, and wellbeing.” Located on CERN’s Prévessin Campus on the French side of the France-Switzerland border, the proposed B777 building comprises a circular design with a sheltered courtyard in the center. Inside, the building will contain office, laboratory, and workshop spaces.

The Irish property investor and developer Iput has secured planning permission to deliver an additional 12 units at Nexus Logistics Park. Planning for an initial 800,000 sq ft at Nexus Logistics Park was granted last year. Following the addition of these new units, which are expected to span 1.7 million sq ft, Iput now has permission to build a total of 2.5 million sq ft across 17 buildings at the site. …Each unit can be constructed with a glue-laminated timber frame, while the buildings are expected to have roof-mounted solar panels, LED lighting and rainwater harvesting systems. …“Our ambition is for Nexus to be one of the most sustainable logistics parks in Europe,” Iput’s chief investment officer Michael Clarke said.

Mass timber has the potential to be a critical building component for the cities of the near future given the need for the construction sector to reduce its reliance on concrete and steel to lower its Co2 emissions. However, as this market grows and mass timber buildings evolve to greater heights, the construction risk landscape will also be transformed, bringing risk management challenges for companies, according to the new Emerging Risk Trend Talk report from Allianz Commercial. “The emergence of mass timber as a sustainable construction alternative represents a significant opportunity for the building sector to reduce its carbon footprint while also satisfying a demand for a material that is more cost-efficient but as durable as steel and concrete,” says Michael Bruch, Global Head of Risk Advisory Services at Allianz Commercia. … The main hazards and challenges include fire, natural catastrophes, water damage, manufacturing, supply chain and faulty workmanship issues.”

Researchers discovered a novel method for converting waste heat into power using sustainable Irish wood products. According to the University of Limerick experts, this is a sustainable strategy that reduces expenses and environmental impact. The study shows the effective generation of electricity utilizing “low-grade heat recovered from lignin-derived membranes.” …Low-grade heat is defined as thermal energy generated at temperatures below 200 degrees Celsius. …“Despite its potential, utilizing low-grade thermal energy in energy harvesting applications has been challenging due to the lack of cost-effective technologies,” added Maurice Collins, professor of materials science at UL’s School of Engineering. …Lignin is a commonly neglected residue of wood in paper and pulp manufacture. The researchers found that these membranes may transform waste heat into electricity by harnessing the movement of charged atoms (ions) within the material. …This is said to be the first lignin-based membrane for ionic thermoelectric energy harvesting.

Cannabis sativa – or specifically its non-psychoactive variant, hemp – is being touted for building blocks for housing that may avoid some of the environmental, logistic and economic downsides of concrete. The cement industry is responsible for about 8% of carbon dioxide emissions, alongside problems created by unyielding surfaces and low R-value properties. The search for large-scale alternatives has so far yielded few results, but on a small scale there are intriguing possibilities, including the use of hemp mixed with lime to create low-carbon, more climate healthy building materials. …Recently hemp’s ability to capture more than twice its own weight in carbon – twice as fast as traditional forestry – has come into focus. By some estimates, hemp can capture up to 15 tonnes of CO2 per hectare, through photosynthesis. Hemp cultivation taking up only 25% of the world’s agricultural land used for dairy and livestock would close the UN emissions gap of 23 gigatons of CO2 annually.
