The paper presents the problem of wood wastes and wood management in Poland. The overview of obligatory European directive and Polish law acts dedicated to wood wastes was presented. The special attention was focused on the actual problems concerned with the introduction of the circular economy and Life Cycle Assessment. The current Polish classification of wood wastes was shown. Moreover, the present sustainable management of wood wastes and raddled wood was analysed.

Stocks And Flows

More sustainable management of phosphorus requires comprehensive understanding of phosphorus stocks and flows. With the purpose of shedding light on the possibilities for an increased level of recirculation of phosphorus in Sweden, phosphorus flows entering and exiting biomass production sectors were quantified along with waste flows, that is, flows that are not currently utilized in biomass production. Relevant waste flows were also characterized in terms of phosphorus concentration, plant availability, contamination and geo-spatial distribution. The theoretical recirculation potential of phosphorus in Sweden was then estimated. The results indicate that there is a large potential for making phosphorus management more circular, especially regarding the utilization of phosphorus in sewage sludge as well as wood ashes from the forestry sector. Moreover, there is a large amount of phosphorus in mining waste that could potentially be used for fertilizer production. It is concluded that the amount of phosphorus in flows fit for recirculation in forestry could more or less balance today’s output. In agriculture, however, recirculation can only sufficiently replace imported mineral phosphorus at current demand if the phosphorus in mining waste is utilized. Thus, if the goal is to replace all of the mineral phosphorus, the agricultural sector also has to become much more efficient in its phosphorus usage.

Legislative Framework

<p>The circular economy approach represents a strategy to optimize product lifecycles, thus improving the sustainability of consumption patterns. In the European Union a recent legislative proposal has addressed this concept by promoting waste prevention and re-use as well as extensive recovery of materials. Such approach is particularly interesting for the management of Waste Electrical and Electronic Equipment (WEEE), that is regarded as an urban stock of different metals, and in particular of both precious metals and rare earth elements. The recovery of metals is the main focus of WEEE management strategies and, more recently, it has been receiving a great deal of attention, especially due to the continuously increasing production of this waste stream. However, great room for improvements can still be recognised to ensure the overall sustainability of WEEE management. The present work discusses both the current needs and the main challenges regarding WEEE management in a circular economy perspective. To this end, WEEE generation trend and composition is provided and the legislative framework for its handling is overviewed, in order to point out future perspectives to develop a more sustainable management approach of this waste.</p>

The production of Solid Recovered Fuel (SRF) and related energy recovery in the European cement industry represents the state of the art in waste management, having evolved into a highly important part of a sustainable and circular economy. This paper describes the production and quality of eight Solid Recovered Fuels (SRF) of PREMIUM quality that are produced from Municipal (Mixed) and selected Commercial Wastes (i.e. Bulky and Lightweight Fraction from Plastic Sorting Plants) in three types of treatment plants located in four European countries, namely Austria, Croatia, Slovenia and Slovakia. The investigated SRF PREMIUM Quality was produced in three different Plant Types applying various process technologies. All three types have been investigated and are described in detail (i.e. flow sheet). Eight SRF PREMIUM Qualities have been comprehensively investigated by sorting, sieving, and physical-chemical analyses. Analyses performed are in accordance with (inter)national standards (i.e. Austrian “ÖNORM”, European “EN” standards and CEN TC 343 guidelines). The results gained show that all investigated SRF fulfil the Austrian quality requirements for heavy metals before co-incineration in the cement industry and it can be confirmed that SRF produced in the investigated plants in Austria, Croatia, Slovenia and Slovakia in fact may be declared as “SRF PREMIUM Quality” that can be used for energy recovery on the European SRF market and utilized in the European cement industry.

Abstract This article explores the regulation of transboundary movement of e-waste into Nigeria. The country has had an unsavoury history with the transboundary movement of hazardous wastes, and this has likely influenced its strict legislative response to such imports, including the decision to ban the transboundary movement of e-waste. However, the effectiveness of the ban is doubtful, as the importation of non-functional electrical and electronic equipment (EEE) or near-end-of-life EEE (which is classified as e-waste in Nigeria), is still thriving. The failure of the ban in curbing the transboundary movement of e-waste into Nigeria obliges policy makers to come up with new and innovative means to address this issue. It posits that the ban does not show an appreciation of the socio-economic realities and the generally weak regulatory climate in the country. The article thus argues for a shift in policy from outright ban of e-waste imports into Nigeria to more effective regulation and sustainable management.

Dominant Designs

To facilitate the adoption of the circular economy (CE) in the architecture, engineering and construction (AEC) sector, some authors have demonstrated the potential of recent designs that take into account the sustainable management of an asset’s end-of-life (EOL), providing an alternative to the dominant designs that end with demolition. However, there is no review of the literature that encompasses a large range of sustainable designs in the current CE context. This paper provides a critical review of journal papers that deal with the barriers to implementing sustainable designs and approaches to the EOL management of assets that have the potential to fulfil the principles of the CE. Eighteen approaches related to prefabrication, design for change, design for deconstruction, reverse logistics, waste management and closed-loop systems were found. Through an analysis of the barriers that are common among these 18 approaches, we classified them into six different categories (organisational, economical, technical, social, political and environmental). Two Sankey diagrams illustrate the interrelation between the barriers, their categories and the 18 approaches. The diagrams clearly show that most of the barriers are common to multiple approaches and that most of the barriers relate to organisational concerns. The study gives a detailed map of the barriers that would help stakeholders from the AEC sector develop strategies to overcome the current obstacles in the shift to a CE.
