Abstract [en]

Symbiotic linkages in industry clusters in the form of interconnected materials, energy and information flows, and close proximity provide unique opportunities to develop efficient environmental strategies. The purpose of our study is to examine the practical potential of applying a life cycle approach in strategy evaluations, as the environmental impact caused by industrial symbiosis systems outside the company gates has been scarcely addressed. This is done by evaluating two strategies for an industry cluster in Sweden: (1) to replace a share of the fossil feedstock used in the industry cluster with forest-based feedstock and (2) to improve energy efficiency through thermal energy integration. The environmental impact reduction potential of the strategies is evaluated using life cycle assessment. The ratio between investment cost and reduced global warming potential is used as an indicator to evaluate the cost-effectiveness of the strategies. Results demonstrate the importance of applying a life cycle perspective as the assessment outcome depends heavily on whether only on-site consequences are assessed or if upstream and downstream processes are also included. 20% of the greenhouse gas emission reduction of the energy integration strategy occurs off-site, whereas the forest strategy has the largest reduction potential off-site, >80%.

Abstract [en]

A variety of climate mitigation strategies is available to mitigate climate impacts of buildings. Several studies evaluating the effectiveness of these strategies have been performed at the building stock level, but do not consider the technological change in building material manufacturing. The objective of this study is to evaluate the climate mitigation effects of increasing the use of biobased materials in the construction of new residential dwellings in Sweden under future scenarios related to technological change. A model to estimate the climate impact from Swedish new dwellings has been proposed combining official statistics and life cycle assessment data of seven different dwelling typologies. Eight future scenarios for increased use of harvested wood products are explored under different pathways for changes in the market share of typologies and in energy generation. The results show that an increased use of harvested wood products results in lower climate impacts in all scenarios evaluated, but reductions decrease if the use of low-impact concrete expands more rapidly or under optimistic energy scenarios. Results are highly sensitive to the choice of climate impact metric. The Swedish construction sector can only reach maximum climate change mitigation scenarios if the low-impact building typologies are implemented together and rapidly.

Abstract [en]

In Sweden, the current dominant valorization of food waste is the production of biogas. However, as current production has low profitability, other options are sought to find more valuable uses of food waste, e.g. as the feedstock for bio-based chemicals. One example is the use of food waste in the production of bio-based succinic acid. In this paper, a LCA study is presented in order to highlight whether biogas production or the production of succinic acid has the lowest environmental impact as valorization option for mixed food waste, and if mixed food waste could be an environmentally preferable feedstock to succinic acid production. The LCA study shows that the environmental results depend on the perspective. From a valorization perspective, food waste has the lowest environmental impact the biogas production. From a feedstock perspective, mixed food waste is an environmentally preferable feedstock to succinic acid production. Although many uncertainties exist because production processes are still being developed, it can be concluded that mixed food waste seems to be a promising feedstock for bio-based chemicals from an environmental point of view, and is of interest to be included in future assessments of bio-based chemicals for the emerging bio-economy. © 2018

Abstract [en]

Bioplastics are gaining attention as a means of reducing fossil resource dependence. Most bioplastics differ from fossil-based plastics in molecular structure, and therefore in terms of properties and durability. Still, the life cycle environmental performance of bioplastics has attracted limited attention in research. The purpose of this study is therefore to examine the importance of applying a life cycle perspective and identify key considerations in the environmental evaluation of bioplastics and bioplastic products under development.

The climate impact of the life cycle of an engine component storage box currently made of the fossil-based plastic acrylonitrile butadiene styrene (ABS) is compared to a hypothetical case study, based on laboratory observations, of the same box produced from a blend of polycarbonate and the bioplastic polylactic acid (PC/PLA) and a box made of biopolyamide (PA1010). The comparison is conducted with a cradle-to-grave attributional life cycle assessment. The functional unit of the study is five years of service life, which reflects the required function of the storage box.

Whereas the climate impact of the production of the different plastic materials differ only slightly, the PC/PLA engine component storage box was found to have a significantly higher climate impact that the ABS and PA1010 boxes when the whole life cycle is taken into account. The dominant contributor to climate impact is premature material deterioration due to humidity and heat during service life, which prevents the product from fulfilling the required function. Two other influential aspects are the possibility of material reuse and the share of fossil or biogenic carbon in the product. Production of plastic materials and boxes, and transport distances, are of less importance.

Results demonstrate the high significance of including service life and potential material deterioration when bioplastics and fossil-based plastics are compared. Our findings underline the importance of applying a life cycle perspective and taking into account the intended application and function of bioplastics as part of their development and environmental assessment.

Abstract [en]

Within the current political and industrial transition to a bio-based

economy, food waste can be an alternative resource for biobased chemicals. This

chapter describes a case study that evaluates the prospect for Swedish production of

biobased chemicals such as succinic acid from food waste. The evaluation is

addressed from multiple systems perspectives. From a technical and resource

system perspective, the results of the case study show that production seems possible.

However, from a social system perspective succinic acid production currently

lacks institutional support and actor commitment and alignment for realizing

development in Sweden. From an environmental and life cycle perspective, the

scoping of the analysis is decisive for the results. The study shows that multiple

perspectives complement each other when seeking a nuanced evaluation of technical

innovation and give insights for the intended value chain.

Abstract [en]

Life cycle assessment and life cycle cost analysis are suitable tools in trying to minimize environmental impact and cost. To get reliable results it is crucial to set up correct system boundaries for the investigation, but it is often difficult to understand a complex products system because of the cascade effects of consequences that can be induced even by small changes. In this paper the effects and consequences evaluation (ECE) method is introduced to systematically identify and organize the effects and consequences for a design change of parts of a complex system. The method is applied in a case study of external wall insulation for a new building to investigate the importance of correct system boundaries. Using the methodical approach in identifying all significant consequences showed that unexpected unit processes can be important when deciding on the relevant system boundary. We also conclude that such processes can have a significant impact on the final results by calculating the change in global warming potential and life cycle cost for the processes affected by the design option.

Abstract [en]

The relative environmental impact from the building construction phase is increasing compared to the operation phase for new buildings. Therefore, it is important to consider the complete environmental life cycle of energy improvement measures. Many advanced optimization methods have been developed in recent years to assess building life cycle impact. However, these previous studies have not fully addressed the secondary effects, in other words, indirect effects outside the actual design option. This may lead to conclusions of optimization studies based on misleading calculation results. The main purpose this study was to highlight the relevance of including secondary effects in optimization of building design with respect to global warming potential and cost. This was done by conducting a parameter study of the building envelope insulation thickness with regard to global warming potential and life cycle costs, while considering secondary effects induced by the different design options. Findings from this study show that secondary effects influence the system boundary, algorithm architecture, results and the final conclusions of optimal building design. Omitting secondary effects can thus lead to incorrect decision on optimal solutions with regard to global warming potential and life cycle cost. Therefore, it is therefore important to take them into consideration when performing optimization studies of building design options.

Abstract [en]

In a sustainable society, the use of resources and climate issues needs to be reduced, and the introduction of services seems to be the solution in the new “service” economy. Similar to products, services are designed to fulfill costumer needs. However, customers are seldom involved in the design of products, while they are in the process of service design. Here we look at the leisure service sector to find method concepts for sustainable analysis (Berlin & Brunklaus 2016).

So far, a literature study and LCA studies on services (Brunklaus 2016) like the opera and theatre (Algehed et al 2010), tourist (Brunklaus et al 2015), and film (Brunklaus et al 2015) has been performed using a producer and consumer perspective, which led to discussion about the reuse of scenes at the opera, and discussion about tourist packages and discussion about film production design. To get this even further, we have looked into the area of service design.

The purpose of this project is to further develop the various LCA based methods (E-LCA, S-LCA, LCC) in order to integrate user into the design process. The questions are: What can the life cycle methodology learn from service design? What are the similarities and differences?

The service design includes several parts: Prepare and define the problem, capture the service and user through ethograpichly oriented research tools, Understand the employee and the user, Improve the working process, and Renew the user function (SP service LABs 2016). The life cycle methodology includes also several parts: Goal and scope including the problem and the system of study, the Inventory includes the technical system and environmental or social or economic data, the Impact Assessment includes indicators, and the Interpretation includes technical solutions and hot spot analysis of various kinds (Bauman and Tillman 2004).

The results show that the service design is developed close to the customer, including study visits and observation, which the life cycle methodology seems to lack. On the other hand the life cycle methodology gains in the well-structured goal and scope. In order to develop the life cycle methodology further we therefore recommend integrating the user more and focusing on the implementation and visualization, similar to Service design.

Abstract [en]

As life cycle assessments are often conducted to provide decision support, it is important that impact assessment methodology is consistent with the intended decision context. The currently most used climate impact assessment metric, the global warming potential, and how it is applied in life cycle assessments, has for example been criticised for insufficiently accounting for carbon sequestration, carbon stored in long-lived products and timing of emission. The aim of this study is to evaluate how practitioners assess the climate impact of forest products and the implications of method choice for results and decision-making. To identify current common practices, we reviewed climate impact assessment practices in 101 life cycle assessments of forest products. We then applied identified common practices in case studies comparing the climate impact of a forest-based and a non-forest-based fuel and building, respectively, and compared the outcomes with outcomes of applying alternative, non-established practices. Results indicate that current common practices exclude most of the dynamic features of carbon uptake and storage as well as the climate impact from indirect land use change, aerosols and changed albedo. The case studies demonstrate that the inclusion of such aspects could influence results considerably, both positively and negatively. Ignoring aspects could thus have important implications for the decision support. The product life cycle stages with greatest climate impact reduction potential might not be identified, product comparisons might favour the less preferable product and policy instruments might support the development and use of inefficient climate impact reduction strategies.
