“…Supply and Use tables (SUTs), and the Input-Output tables (IOTs) that are derived from them, provide decision-makers with detailed information about the workings of the economy . This is not only used for economic planning but also to understand pollution (Druckman et al, 2008), sustainability (Dietrich et al, 2012;den Boer et al, 2014) and much more. The more detailed this information is, the better it is for decision making (Wood, 2011).…”

This paper investigates the benefits of using a boundary tightening algorithm to improve the quality of the data used in Supply and Use Table (SUTs) Balancing, building on similarities with certain approaches to Statistical Disclosure Control. Boundary tightening was shown to significantly improve the quality of the finally balanced SUTs well beyond that of existing techniques. Most notably, improvements occurred when boundary tightening was applied prior to the balancing processshowing that it can be used as a valuable preliminary to other approaches. It also multiplied the improvement in SUTs quality when more accurate updated information was added to the SUTs. The findings of this paper strongly suggest that this boundary tightening algorithm will improve the quality of the output of the balancing process and it is equally likely to be useful when applied to other processes that handle uncertain data.

“…The circular economy (CE) has been identified with a system, in which the growth of the economy is decoupled from resource consumption, through material recovery and recirculation [1,2]. In order for the CE to be implemented, it is necessary to move from a linear (take-make-dispose) model, in which a large amount of waste is generated, to a circular system, where resources are preserved throughout the production cycles [3,4]. In the shift towards the CE, consolidated efforts need to be taken in virtually all business sectors.…”

Energy Recovery from Waste—Closing the Municipal Loop

Municipal waste management in the EU has been challenged to a thorough transformation towards a Circular Economy. It is addressed by a number of quantitative policy targets, including a restriction on municipal waste landfilling to 10% in 2035. This paper presents the data on municipal waste composition in a large Polish city, based on thorough waste sorting analyses. On average, 374 kg of municipal waste is collected per capita in Wroclaw, of which 41% are separately collected fractions. The approach to implement the EU recycling targets until 2035 is presented, including an increase of sorting and recycling efficiency and a significant share of recyclables being retrieved from the residual waste fraction. Notwithstanding the recycling targets, an important stream of residual waste remains, amounting to 200 k ton in 2020 and approx. 130 k ton in 2035, which is available for energy recovery. The respective LHV values range from 8.5 to 7.6 MJ/kg. The results indicate that the residual waste stream, after satisfying the recycling targets, is still suitable for energy recovery through the whole period until 2035. Moreover, it is a necessary step towards closing the materials cycling in the municipal sector and the only option so far to reduce landfilling sufficiently.

Wasted materials represent valuable resources that we can no longer afford to discard. The concept of 'zero waste' is a challenge to old ways of thinking, calling for waste to be viewed as a potential resource with value to be realised, rather than as a problem to be dealt with, usually by burial in landfill sites or incineration without energy recovery. Examples of industrial symbiosis -the theoretical rationale and methods for sharing information and resources across different industriesare starting to be found worldwide. In this themed issue, we focus on technological issues. A short overview of the themes that are discussed in detail in the individual papers is given below. The key concepts of the Zerowin vision (outlined in the briefing by den Boer et al. (2014)) formed the foundation of the demonstration case studies presented in this journal.One of the methods deemed promising for the zero waste strategies is the holistic design for recycling, repair, refurbishment and reuse (D4R). Two of the Zerowin case studies apply this methodology for high-tech products: a laptop and a photovoltaic (PV) system. The D4R laptop case study (Hickey et al., 2014) has demonstrated an industrial network established by a laptop manufacturer MicroPro with end-of-life IT asset management firms, IT refurbishers, component manufacturers and local industries. The innovative idea was to develop a laptop design that allows the creation of a new life for the used IT components, thus turning wastes into products. MicroPro has successfully been able to manufacture a universal shell that is capable of accepting new primary system components and also has the ability to integrate various parts and components (and parts and components of different specifications).The focus of the second case study is a D4R PV system (Arranz et al., 2014). Here, a Zerowin industrial network allowing higher resource efficiency was developed around the PV system prototype, which, at the same time, was designed to operate more efficiently. The demonstration of the PV system case study was carried out in two phases: the first phase concerned the redesign of the power conditioning equipment according to the D4R strategies. The second phase was the demonstration of the D4R design of: (a) a gridconnected PV system at the energy provision company and (b) a stand-alone system installed at the recycling company, both in Spain. The development of the prototype focused on the improvement of the overall PV system efficiency (performance ratio (PR)), the increase of the operational lifetime, the improvement of the overall PV system condition monitoring and the increase of the reliability of the equipment. Improving the PR and the operational lifetime of the different components will enable the reduction of the use of batteries and PV modules -the main contributors of the PV system environmental impacts.The first and second case studies are directly linked to the thirdReUse network (Dietrich et al., 2014). The ReUse network is a value-conservation network that focuses on...
