“…As the thinned log is a by-product from the forestry industry, allocation is required. In this study, economic allocation was used following May et al (2012). In economic allocation, impacts were distributed among co-products according to their market value.…”

Hardwood plantations are slow to mature with low financial returns in the early stage. Veneer Based Composite (VBC) products from mid-rotation plantation thinned trees are currently being developed at Griffith University in partnership with the Salisbury Research Centre, Queensland Government, which may offer an opportunity to improve the industry's profitability and win new markets. Due to shortage in utility solid hardwood poles, VBC poles are proposed as a potential alternative. In this study, greenhouse gas emissions of alkaline copper quaternary (ACQ) preservative-treated VBC pole was assessed using 'cradle to grave' life cycle assessment methodology. ACQ preservative was used to extend the service life of wood poles due to wood products are commonly to be degraded in wet environments subject to microbial or insect attack. The manufacturing process considered in this study is based on the current technologies in Salisbury Research Centre. Two (2) end-of-life scenarios were considered: landfilling and incineration with energy recovery. The function unit was a 1-metrelength pole with 115mm internal-diameter and 15mm wall-thickness. Global warming potential (GWP100) was calculated using the IPCC 2007 method. Results indicated disposal stage contributed the most impact. Incineration with energy recovery had the lowest GWP impact (0.337kg-CO 2 -Eq) followed by landfilling. Transportation distance was identified as a significant parameter affecting the result. Sensitivity analysis indicated that increasing the transportation distance by 100 km would increase the GWP100 by 21% in the incineration option.

“…In addition, plantations could contribute to the mitigation and adaptation of climate change and the impacts on food production by stabilising soils, climate and water flows and enabling pollination (FAO, 2016). Also, as highlighted by May, England, Raison and Paul (2012), forest products from plantations have low embodied energy and, when used as a source of bioenergy have a strong potential for greenhouse gas (GHG) reduction. Regarding the specific contribution of monoculture plantations to the 2030 Agenda, the literature is scarce; however, a report by the Forestry Stewardship Council (FSC), argues that certified forests, including monocultures, have a positive role to play in 11 of the SDGs (FSC, 2016).…”

The forestry sector will play a key role in the achievement of the 2030 Agenda for Sustainable Development. The forestry sector is a pillar of many countries’ economies, including Chile. Despite the many economic benefits of the sector for the country, its contribution to the achievement of the Sustainable Development Goals (SDGs) is not clear, especially for rural communities that co-exist with the sector. This study therefore aimed to identify the impacts of the sector on the sustainable development of rural communities in a Chilean commune, Cabrero, and link these impacts to the SDGs. Based on a mixed-method approach that considers key stakeholders perspectives, the paper finds that the forestry sector has multiple and complex impacts on sustainable development, with both positive and negatives outcomes for rural communities, generating synergies and trade-offs with all of the 17 SDGs. It concludes that while companies play a key role in delivering the 2030 Agenda, the achievement of the SDGs will require collaboration amongst people, government and the private sector to understand and support the delivery of a forestry sector that contributes to the sustainable development of communities in Cabrero and, more generally, in Chile.

“…For example, the cultivation water footprints for many biomass feedstocks were compiled by Mekonnen and Hoekstra (2011) [47], and May et al [48] analyzed water requirements for softwood plantations. These studies and the present one assume that each biomass crop is grown in arable land with typical amounts of rainfall.…”

Abstract:The water footprint of energy systems must be considered, as future water scarcity has been identified as a major concern. This work presents a general life cycle network modeling and optimization framework for energy-based products and processes using a functional unit of liters of water consumed in the processing pathway. We analyze and optimize the water-energy nexus over the objectives of water footprint minimization, maximization of economic output per liter of water consumed (economic efficiency of water), and maximization of energy output per liter of water consumed (energy efficiency of water). A mixed integer, multiobjective nonlinear fractional programming (MINLFP) model is formulated. A mixed integer linear programing (MILP)-based branch and refine algorithm that incorporates both the parametric algorithm and nonlinear programming (NLP) subproblems is developed to boost solving efficiency. A case study in bioenergy is presented, and the water footprint is considered from biomass cultivation to biofuel production, providing a novel perspective into the consumption of water throughout the value chain. The case study, optimized successively over the three aforementioned objectives, utilizes a variety of candidate biomass feedstocks to meet primary fuel products demand (ethanol, diesel, and gasoline). A minimum water footprint of 55.1 ML/year was found, economic efficiencies of water range from −$1.31/L to $0.76/L, and energy efficiencies of water ranged from 15.32 MJ/L to 27.98 MJ/L. These results show optimization provides avenues for process improvement, as reported values for the energy efficiency of bioethanol range from 0.62 MJ/L to 3.18 MJ/L. Furthermore, the proposed solution approach was shown to OPEN ACCESSProcesses 2015, 3 515 be an order of magnitude more efficient than directly solving the original MINLFP problem with general purpose solvers.
