Book Description
This study extends existing life cycle assessment (LCA) literature by assessing seven environmental burdens and an overall monetized environmental score for eight recycle, bury, or burn options to manage clean wood wastes generated at construction and demolition activity sites. The study assesses direct environmental impacts along with substitution effects from displacing fossil fuels and managed forest wood sourcing activities. Follow-on effects on forest carbon stocks, land use, and fuel markets are not assessed. Sensitivity analysis addresses landfill carbon storage and biodegradation rates, atmospheric emissions controls, displaced fuel types, and two alternative carbon accounting methods commonly used for waste management LCAs. Base-case carbon accounting considers emissions and uptakes of all biogenic and fossil carbon compounds, including biogenic carbon dioxide. Base-case results show that recycling options (recycling into reconstituted wood products or into wood pulp for papermaking) rank better than all burning or burying options for overall monetized score as well as for climate impacts, except that wood substitution for coal in industrial boilers is slightly better than recycling for the climate. Wood substitution for natural gas boiler fuel has the highest environmental impacts. Sensitivity analysis shows the overall monetized score rankings for recycling options to be robust except for the carbon accounting method, for which all options are highly sensitive. Under one of the alternative methods, wood substitution for coal boiler fuel and landfill options with high methane capture efficiency are the best for the overall score; recycling options are next to the worst. Under the other accounting alternative, wood substitution for coal and waste-to-energy are the best, followed by recycling options.

The role of wood residues in the transition to sustainable bioenergy
Author: Food and Agriculture Organization of the United Nations
Publisher: Food & Agriculture Org.
ISBN: 9251375038
Category : Technology & Engineering
Languages : en
Pages : 87
Book Description
This report provides an overview of the potential use of wood residues as feedstock for bioenergy production as part of the transition towards a sustainable and circular forest bioeconomy. While data and examples are abundant from developed countries, a specific focus will be put on the role and potential of wood residue-based energy in developing countries. The study is structured around the following four main objectives, each corresponding to a chapter:- define key terms and concepts related to wood residues and bioenergy value chains (Chapter 2);- characterize the status and trends in renewable energy, modern bioenergy and the forest-based bioeconomy and evaluate the theoretical potential of wood residues for energy (Chapter 3);- determine general success factors, common lessons learned and constraints on the utilization of wood residues for energy (Chapter 4); and- formulate recommendations (Chapter 5).The overall aim is to inform new policies and programmes through the identification of optimal conditions whereby the use of wood residues for energy can offer a competitive alternative to other fuels in developing countries and contribute towards reaching the UN SDGs.

Recycling of Biomass Ashes
Author: Heribert Insam
Publisher: Springer Science & Business Media
ISBN: 3642193544
Category : Science
Languages : en
Pages : 171
Book Description
The use of renewable bioenergy is increasing, and so is the production of associated wastes: biomass ashes. This book presents eleven chapters on the options for recycling such biomass ashes, ranging from their use as fertilizer in agriculture and forestry to their application as a supplement for the production of cement-based materials or bricks. The book also examines the pros and cons for each of the different uses of biomass ashes.

Book Description
This report addresses the role of forest products in replacing fossil-based and GHG-intensive products. The overarching objective is to provide recommendations to strengthen the contribution of substitution by forest products to sustainable development. To that end, this report firstly provides an overview of the understanding of the bioeconomy and the role of forest products across the world. Secondly, we present examples of conventional and innovative forest products and describe their role in the bioeconomy. Thirdly, we present a review of the quantitative and qualitative understanding of the environmental impacts and benefits of substituting fossil fuel-based or -intensive products with forest-based products, and of the contribution of substitution to SDGs. Fourthly, we outline the current understanding of the future global demand and supply dynamics of forest products and the potential impact that increased substitution may have on these dynamics. Fifthly, we identify gaps in the global forest product value chain. Finally, it provides recommendations and conclusions, respectively.
