Did you know? Around 600 years ago, workers built parts of the Great Wall during the Ming dynasty using a paste of sticky rice flour and slaked lime. The sticky rice mortar held the bricks together so securely that weeds were unable to grow in several areas. This sticky rice-lime mortar has more stable physical qualities, better mechanical storage, and is more compatible, making it an ideal restoration mortar for ancient masonry. Using sticky rice as a construction material was one of the Ming dynasty's most significant innovations, allowing their structures (including tombs and pagodas) to withstand earthquakes and other elements. In modern times, rice straw can be utilized as a sustainable building material in a variety of applications. One method involves treating rice straw fibers with various chemicals to improve their qualities, such as tensile strength, flexural strength, and thermal stability, and then combining them into composite materials for structural uses in furniture and interiors. Another way rice straw can be utilized is in brick manufacturing, where it has been shown to have lower environmental implications than other brick types such as baked clay and cement, making it a more sustainable option. It can also be coupled with waste plastic film to form straw-reinforced composites with increased physical and mechanical qualities such as tensile strength, bending strength, impact strength, and water resistance, thereby minimizing pollution and maximizing waste material utilization. #FridayFacts with #CECO #sustainability #sustainableconstruction #greatwallofchina

The value chain of ACACIA TREE in VietNam, the main raw material for plywood 1. As the first value chain, acacia wood used as a raw material for the paper industry, it is the market with the highest consumption of acacia wood in Vietnam. To make paper, they can also use many different types of wood. After harvesting the acacia trees, they will peel it and sell it to wood chip factories and then export it to other countries. The main importing countries from Vietnam are China, Japan, and Korea. In 2022, Vietnam exports 16 million tons of wood chips to other countries with a value of 2.7 USD The reason why Vietnamese wood chips have to be exported to other countries is because they own pulp processing technology that has little impact on the environment that vietnamese companies do not have. Acacia wood sold in chip form has a low price, about 50 - 60 USD/ton. It only needs to be planted for 5 years or more to be able to exploit it. Each hectare can harvest 80,000 - 100,000 tons 2. The second value chain of acacia wood is core veneer production. Core veneer is the main material for making plywood. Vietnam is one of the 5 countries that produce and export the most plywood including: China, indonesia, Russia and brazil. In Vietnam, there are two main materials for making plywood including: acacia and Eucalyptus. Plywood made from these materials has the same quality but from acacia wood will be about 15-25$/cbm cheaper because acacia wood is more abundant than eucalyptus wood. and one more thing is if you want to import plywood from Vietnam, You should only enter one of these two types because Other types of wood will not be available much and the quality will be uneven. The type of wood used to peel veneer has a diameter of 13 cm or more, with a lifespan of 7 to 10 years, possibly older. Producers usually buy it at a price of 65-80$/ton 3. The third value chain of acacia trees is for , they used sawn timber for pallet production,finger joint board production, interior exterior like sofa, bed, door production, and export. advantage of acacia wood with another wood is It can naturally resist mold and termites without chemicals. This type of production wood is larger than other types, grown for 10 - 15 years, maybe 20, 30 years and it very hard because them grown from the acacia tree specializes in timber. This type of wood has the highest price, they can buy it by the ton or cbm, the price is from $70 - $120/ton maybe higher.Price depends on size and lifespan. Large, straight trees with long lifespans have higher prices 4. The fourth value chain of acacia wood is pellet production. Vietnam is the second  largest exporter of wood pellets in the world, so this is also a market that consumes a lot of acacia wood. However, producers often use wood industry waste or leftover parts of trees such as branches and small trees. They buy it with very low price, just under 50$ per ton.

Did you know linoleum, vinyl, carpet, and ceramic flooring are a detriment to the environment? Here’s why: Harmful Chemicals Energy-Intensive Manufacturing Excessive Natural Resource Use Disposal in Landfills Carbon Emissions During Transportation On the other hand, concrete doesn’t rely on toxic adhesives or finishes, and it reduces energy consumption by absorbing heat slowly.

HOW TO USE PRONATURE OIL FINISHES? "If there is one single area in woodworking that could be prone to becoming a minefield it would be finishes. Opinions vary about the best products out there and if you happen to have a dozen or so woodworkers in the room and ask them about their preferred finish, you would likely get 12 different answers and I dare say possibly more opinions than the number of people in the room!"

Even though we have a limited space in the urban area, we can start make lots of compost in the following way. Vertical Stackable Compost Bins Structure: Stack multiple bins or trays vertically, each with holes for aeration and drainage. Materials Needed: Durable plastic or metal bins. A sturdy rack or shelving unit. Mesh or perforated plates for separation. Design Steps: Base Layer: Use a large bin or tray to collect excess liquid ("compost tea") from the upper layers. Stack Layers: Place smaller bins/trays with perforated bottoms on top of the base layer. Aeration and Drainage: Add small holes in the sides and bottom of each bin for airflow and drainage. Lids: Use breathable lids or cover each bin with mesh to keep pests out while allowing airflow. Usage: Add food scraps and green/brown material layer by layer, starting from the top bin. When one bin is full, rotate it to the bottom.

For our recycling process, it is essential to separate glass from mineral stone wool. 💎🪨 Can you tell the difference? Both materials share similarities in shape, colour, upholstery, fibre, and structure, making it tricky to differentiate at first glance. In the following weeks we will test your knowledge. And show you how to spot the differences between stone and glass wool. Today's question is about shape: which wool is largely used for flat roofs? 🅰️ stone mineral wool 🅱️ glass mineral wool Spoiler alert! 🛎️ The correct answer is ... stone mineral wool. It is mainly used for high-temperature insulation, fire protection and flat roofs.
