Indonesia is one of the active exporters of logs and sawn wood, so the waste generated is very large. One of the applicable technologies developed for the utilization of wood saw waste is to process it into liquid smoke through the pyrolysis process. The application of liquid smoke to plants can affect plant’s growth and production processes due to the presence of acetic acid and methanol. The purpose of this research was to find out about the properties of Surian sawn waste liquid smoke and how it could be used as a biofertilizer an Arabica coffee seeds. …The effectiveness of liquid smoke from sawn wood waste for the increase in height, stem diameter, and the highest number of leaves of coffee seeds was obtained at a concentration of 2.5%.

“We want our towers to be pleasant to look at, and wood can help us to do that,” says Jean-Claude Geha, chief technology officer at Vantage Towers. Today the company has 84,600 towers to its name, with most of these structures made from traditional materials such as steel. However, Vantage has sought to break from the norm and try a different approach with some of its newer tower structures. This is where wood comes in. Although a very small number – 12, to be precise – of Vantage’s tower portfolio are made from timber. …Founded in 2020 by Vodafone, Vantage Towers operates across 10 European countries. …At present, Vantage has deployed its wooden structures in Hungary and Germany, where, in October 2023, the company announced it was building North Rhine-Westphalia’s first sustainable wooden-structured telecommunication mast in the town of Neunkirchen, Siegerland. The 40-meter high Ecopol tower is set to be erected early this year.

Wood, a traditional and sustainable structural material, has long been used in construction and furniture due to its availability and mechanical properties. However, natural wood’s strength is often insufficient for advanced engineering applications. Now, researchers from Nanjing University have developed a novel self-densification strategy to create super-strong wood that could replace metals and alloys. The team used a combination of partial delignification and a LiCl/DMAc swelling process to release and reorganize wood fibers. This method allows the fibers to move inward and fill the cell lumen, followed by air-drying to achieve self-densification. Unlike traditional compressed wood, which relies on unidirectional compression, this self-densified wood exhibits uniform shrinkage in the transverse area, maintaining its longitudinal dimension.

The headquarters of the construction company Blumer Lehmann in Gossau, Switzerland, illustrate the possibilities of contemporary timber architecture. The collaboration between the Stuttgart-based team at ICD and timber construction specialist Blumer Lehmann builds upon extensive research into curved timber structures. In contrast to the orthogonal grid of the overall building, the tapering surfaces of the atrium articulate two distinct spatial expressions. Convex outward-facing walls offer a textile-like softness, while concave intersections generate sweeping ridges that extend vertically through the structure, modulating light and perspective. These elements simultaneously act as a spatial enclosure and a load-bearing system, transferring forces across five floors with a slender 130-millimeter-wall thickness. The stairway of the atrium is integrated within this timber composition, guiding movement while creating balconies and alcoves.

This study investigates the influence of nanocellulose fibre (CF) derived from wood pulp on the hydration, mechanical, shrinkage, and pore properties of ordinary Portland cement (OPC) mortar. The CF was incorporated into mortar mixes at varying dosages (0.15–1.5% by weight of mortar) to evaluate its effect on physical, mechanical, and microstructure properties. …The results suggest that an optimal CF dosage of 0.45% provides a balance between workability, mechanical properties, and durability, making it an effective additive for enhancing the performance of OPC mortars in sustainable construction applications. The study promotes the use of recycled cellulose fibres in mortars, which helps reduce the reliance on non-renewable resources. By carefully managing CF content, it is possible to achieve an acceptable balance between workability, mechanical strength, and durability. 

The Australian Forest Products Association (AFPA) has launched a candid new video that demonstrates the importance of the essential and sustainable products our sector creates, Chief Executive Officer of AFPA, Diana Hallam said today. “This video Try living without Aussie timber and paper is the latest development in AFPA’s 2025 Federal Election Campaign following the launch of our policy Platform Australian Timber.

Unlike traditional engineered timber, which relies on subtractive processes such as cutting and laminating, Woodflow builds material only where it is needed, says Daniel Ortiz del Río, architect and a chief technology officer at strong by form, a company that creates lightweight structural solutions combining the sustainability of wood with high performance and productivity. …”By combining materials science, digital fabrication, and computational design, we create ultra-lightweight yet structurally strong components that outperform conventional materials in sustainability, weight, and mechanical performance,” he added. …Del Río emphasizes that using Woodflow technology reduces wood consumption by up to 75 percent, significantly lowering carbon emissions compared to natural wood. …”A key advantage of our process is that we maximize the efficiency of forest resources by using veneer in the form of flakes, allowing us to utilize a much larger portion of the tree for structural applications,” Del Río explained.

UK — The Measuring Mass Timber project presents research led by architecture practice dRMM, conducted in collaboration with Edinburgh Napier University and the Quality of Life Foundation. The methodology was developed with a goal to assess the quality of life and whole-life carbon impacts of five case study projects across different sectors. These are UK buildings for education, infrastructure, worship, residential and commercial uses. According to the report, mass timber is a readily available option to help achieve embodied carbon targets, while the quality of life assessment of the case study buildings show benefits healthwise. Each building was subject to detailed lifecycle analysis, internal environment monitoring and user consultation over the two-year study. dRMM believes this could be seen as a first step in building an evidence-driven case for timber construction using whole-life carbon and wellbeing metrics.

Ms Zimmi Forest, a basket weaver in northern New South Wales, has tapped into the desire to do death differently, and her workshops have been booked solid since they started 18 months ago… Ms Forest said the idea of weaving coffins came to her after she was invited to make baskets at a property where a Landcare group was working to remove invasive Cat’s Claw vine. The Brazilian vine is perfect for weaving; once it is stripped from the trees and pruned back, it forms long, flexible strands. “The great thing about a woven coffin is it’s permeable, all the microorganisms in the soil can get in and its breaks down so much quicker. “For cremation, why would you burn solid timber?” The process to make a woven coffin took about 150 hours, and Ms Forest said she had made about 15 coffins at the workshops and on her own as commissioned projects.

NEW ZEALAND — Signing of a ‘letter of intent’ on forestry co-operation between New Zealand and India as part of the Prime Minister’s delegation visit to India this week is welcomed by the Wood Processors and Manufacturers Association of Newzeald (WPMA). The ‘letter of intent’ is between the Ministry for Primary Industries and our nearest counterpart Indian agency, the Ministry of Environment Forestry and Climate Change. The key subject areas, reflecting MOEFCC’s and MPI’s respective mandates and scope, includes sustainable forest management; research and innovation; education and capacity building; and utlilisation and certification. …India is the most populous nation in the world yet for our forestry exports India currently ranks 11th (down from 5th in 2019). …With a recent ruling from the Indian government stipulating that federal housing schemes include ‘a greater mix’ of wood, there are new opportunities opening, for example, in the Indian residential market for our sustainable wood products.

Amid growing interest in sustainable construction, CHYBIK + KRISTOF is advancing the position of timber architecture in Central Europe. Titled Forestry in the Forest, the project will serve as the new headquarters for the Czech National Forestry in Hradec Králové and become the Czech Republic‘s largest wooden structure in an effort to shift industry norms and position timber as a viable material for large-scale development. The complex is envisioned as a cluster of five elongated timber volumes … connected through a central hall. …Forestry in the Forest’s structure then makes use of a combination of timber construction methods … to demonstrate wood’s capacity to deliver efficient, durable, and engaging design solutions. …‘The walls are constructed in the two-by-four system; the ceilings, horizontal slabs, built-in subcenters and railings are made of CLT panels; and for the large-span structures wooden glued trusses are used,’ says CHYBIK + KRISTOF.

LONDON – Ambitious new plans to increase the use of timber in construction were announced by Environment Minister Mary Creagh at the Timber in Construction Summit in London. The new Timber in Construction (TiC) Roadmap is being introduced to help get Britain building using timber – creating economic growth, rural jobs and helping meet housebuilding targets in a sustainable way. The TiC Roadmap was first published at the end of 2023. This new and improved version goes even further, highlighting the Government’s ambition to boost the domestic timber industry and kickstart the construction sector without compromising on quality, safety or carbon emissions. …Alex Goodfellow, Chair of the Confederation of Timber Industries, and CEO of Donaldson Offsite, represented the timber industry when he said: “The Minister’s support for the Timber in Construction Roadmap shows the Government’s firm commitment to a growth agenda: growth for forestry, for housing, for low-carbon skills and for the economy.

A new study led by dRMM in collaboration with Edinburgh Napier University and the Quality of Life Foundation has highlighted the low-carbon and wellbeing benefits of five mass timber buildings in the UK. The study demonstrates that mass timber buildings not only significantly reduce carbon emissions but also provide healthier and more comfortable environments for occupants, its authors claim. The research, titled Measuring Mass Timber, found that these structures produce, on average, 50 per cent less embodied and operational carbon than conventional buildings. Additionally, they foster a strong sense of comfort and connection to nature among users. The findings were released as Government plans to increase the use of timber in construction were announced yesterday by Environment Minister Mary Creagh at the Timber in Construction Summit, coinciding with the launch of an updated Timber in Construction Roadmap.

A Hawke’s Bay trial to convert leftover forestry wood into roading material for logging trucks to travel over is showing promising results. Managing woody debris left after harvesting is a common challenge in forestry. …Transporting it out of the forest is costly, while leaving it piled on landings poses environmental risks during severe weather events. With funding from Forest Growers Research (FGR), Pan Pac and FGR have been trialling a promising solution – using it as roading material. …Compared to metal roads, shredded wood roads offer the environmental advantage of repurposing waste wood while reducing traditional roading material transport distances, thereby lowering the carbon footprint. …The results so far indicate that shred wood roads could be a viable alternative to metal roads, where the grade is not too steep in wet conditions.

Humans have been building with wood for thousands of years, but the last few decades have seen a renaissance in timber construction with the rise of mass timber. Products like cross-laminated timber (CLT) and glue-laminated timber (GLT) have exploded in popularity recently with ever larger and more elaborate buildings completed. Australia has been punching above its weight on a global stage with several landmark examples attracting worldwide acclaim… Many projects delivered so far have been relatively “purist” buildings with most components made from mass timber but products are becoming normalised to a point where we can pick the right material for the right job. Timber is an incredibly capable material, but can be limited in some applications, so often a hybrid approach is a better way to get timber into more projects.

Researchers at Stockholm University have developed a fully biobased hair conditioner using lignin gel emulsions, offering a sustainable and environmentally friendly alternative to conventional haircare products. Hair conditioners typically contain 20–30 ingredients, many derived from petroleum and oleochemicals, raising concerns about sustainability and environmental impact. A new study published in Science Advances, demonstrates that micellar lignin gels can effectively stabilize emulsions with natural oils, reducing the need for synthetic surfactants and complex stabilizers commonly used in commercial formulations. The research team, led by Mika Sipponen at Stockholm University, sought to explore lignin, a common and renewable component in wood biomass, as a multifunctional component for hair conditioning. “By using wood-derived lignin directly without any chemical modification, we not only simplify the ingredient list but also eliminate the need for organic solvents, making the process more eco-friendly,” said Sipponen.
