Wood waste in Sweden

Today, about 2 million tons of wood waste is generated per year in Sweden

Globally, nearly 30–40% of total solid waste are from construction and demolition waste. Wood waste is the second largest fraction after concrete and contributes 20–30% of the total construction and demolition waste. It is estimated that around 10–15% of the timber used in new construction goes to the waste stream.

Wood resources are utilized in various industries due to their versatility, durability, and natural aesthetic appeal. Here are some examples of how wood resources are used in different industries:

  • Construction and Building
  • Furniture and Cabinetry
  • Packaging and Pallets
  • Paper and Pulp
  • Woodworking and Crafts
  • Flooring and Interior Design
  • Energy Production
  • Outdoor and Landscape

These examples demonstrate the diverse applications of wood resources across various industries. Sustainable forest management and responsible sourcing practices are crucial to ensure the long-term availability of wood resources and minimize environmental impact. However, wood waste is a significant environmental concern. Here are numbers about wood waste from construction and demolition:

Sustainable practices can help address this issue effectively and some sustainability practices related to wood waste include:

Reduce and Minimize Wood Waste. One of the primary approaches to managing wood waste sustainably is to focus on waste reduction and prevention. This involves optimizing cutting and manufacturing processes to minimize waste generation, using efficient machinery and techniques, and training workers to ensure accurate measurements and cuts. By reducing waste at the source, less wood ends up as waste in the first place.

Reuse and Recycling. Reusing and recycling wood waste is an effective way to minimize its environmental impact. Wood waste can be repurposed for various applications, such as construction materials, furniture, crafts, and biomass energy production. By finding alternative uses for wood waste, valuable resources are conserved, and the demand for virgin wood is reduced.

Composting. Certain types of wood waste, such as sawdust and wood chips, can be composted. Wood waste can contribute to organic matter in composting systems, which can then be used as nutrient-rich soil amendments in landscaping, gardening, and agricultural applications. Composting wood waste helps divert it from landfills and supports soil health and fertility.

Energy Recovery. Wood waste can be utilized as a renewable energy source through processes like biomass combustion or gasification. This involves converting wood waste into heat or electricity, which can be used for industrial purposes or distributed through power grids. Energy recovery from wood waste reduces the reliance on fossil fuels and minimizes greenhouse gas emissions.

Responsible Disposal. If wood waste cannot be effectively reused, recycled, or recovered for energy, responsible disposal methods should be implemented. Properly managing wood waste disposal involves complying with local regulations, ensuring it is not illegally dumped or incinerated, and considering environmentally friendly options such as using designated waste management facilities.

Sustainable Forest Management. Implementing sustainable forest management practices can help reduce overall wood waste generation. This includes responsible harvesting techniques, selective logging, and reforestation efforts. Sustainable forest management ensures the long-term health and productivity of forests, reduces deforestation, and promotes a continuous supply of wood resources while minimizing waste.

Education and Awareness. Promoting awareness and educating stakeholders about the importance of wood waste management is crucial for sustainable practices. Training employees, contractors, and consumers about waste reduction, recycling options, and responsible disposal methods can help foster a culture of sustainability within the wood industry.

It is important for businesses, governments, and individuals to collaborate in implementing these sustainable practices related to wood waste. By adopting waste reduction strategies, promoting recycling and repurposing, and integrating responsible disposal methods, the environmental impact of wood waste can be minimized, contributing to a more sustainable and circular economy.

Product Category Rules

The interest for Environmental Product Declarations continues to grow, however, it can happen that companies offer products for which EPD does not yet exist.

In this case, new Product Category Rules (PCR) need to be developed. 📗

PCR refer to a set of rules according to which EPDs are made. Each program operator is responsible for overseeing the development of PCRs and ensuring that they meet the requirements of the relevant standards and their own General Program Instructions.
