This study delivers the first empirical findings on the relevance of digitisation to improving material efficiency based on the German company survey ‘IW-Zukunftspanel’.

German manufacturing firms have up to now only rarely digitised material efficiency measures to a great extent. If they are - particularly in large companies - they tend to be used for process optimisation. Around two fifths of the companies are at least moderately digitised in relation to the most important industrial efficiency measures, namely process optimisation and the use of new techniques, but there is still more than a third that is not at all. Companies have most frequently digitised cross-company materials cycles, but this instrument is only applied by two fifths of industrial companies. There is still potential for more digitisation of measures relating to product design, materials cycle management and new business models.

At least every other manufacturing company reuses residue and waste materials via internal circulation systems. Nevertheless, for two fifths of these companies digital networks do not play any part and in the case of a further two fifths, the part they play is minor. Only one in ten companies is heavily digitised. More than half of industrial companies use resource-saving measures that begin at the product design stage. To date, almost half of these companies are not digitally networked, or if they are, it is only to a small extent. One third of the industrial companies up to now have considered new business models as an efficiency-raising way. Of these, three out of ten have not been digitised yet with a further two fifths having only a minor level of digitisation.

Companies that have already embedded digitisation in their strategy are frontrunners for greater material efficiency, since they more frequently use material efficiency measures intensively, are more likely to recognise further potential savings and their efficiency-saving approaches are also clearly more often highly digitised.

Mountain areas face specific natural conditions, such as slope, climate, and soil types, that make the exploitation of mountain resources difficult.

Other challenges associated with connectivity and transport make economic activity all the more challenging.

The adoption of the circular economy will be particularly important in mountain areas which contain exceptional primary resources such as forests, water, and minerals, and provide ecosystems services such as carbon sequestration, clean water, landscapes, and recreation. Maximizing the value of extracted resources and managing them sustainably is particularly important for maintaining a high quality of life in mountain territories.The circular economy can create new economic opportunities that will provide much needed employment and economic growth in mountain areas.

The development of the circular economy in mountain areas will allow inhabitants to benefit from resources and services available in the mountains. It will also drive the development of new approaches, for example in governance, technology, or in the building of novel tools, in so doing providing new opportunities for jobs and growth in mountain regions.

This study focuses on the forest sector as the sector is particularly adapted to a circular approach in mountainous areas in Europe.

Since 2000, the “Slovenian Entrepreneurship Observatory” publishes a report annually providing analysis of the situation of Slovenian companies and insight into Slovenian entrepreneurship. In 2018 this report had a thematic focus on the circular economy (CE), with the authors centring in on the drivers and barriers to SMEs integrating CE into business practice.

This report first provides a theoretical framework for the CE, which aims to raise awareness and facilitate information exchange between companies and individuals looking to spread circular innovation. Simultaneously this report also provides an overview of the barriers companies face in transitioning towards circularity, which include a lack of comparable indicators to benchmark and track progress; cost of eco-design; administrative burden; access to finance and a lack of awareness about the concept itself: in 2017, a survey of businesses indicated only 32% had some understanding of what a circular economy is. This survey also revealed businesses perceive economic, environmental and regulatory opportunities as the main drivers towards circularity.

The report concludes with practical aspects of CE implementation at the level of enterprises, presenting a case study which highlights the situation and the possible use of eco-design in Slovenian SMEs operating in the construction sector and conclusions with recommended steps to overcome the barriers identified.

The built environment, consuming almost half of the world's resources extracted every year and responsible for a massive environmental footprint, is a fundamental sector in the circular transition.The circular economy has great potential to help meet global sustainability targets and the Paris Agreement's goals in particular.
Moving towards a circular built environment involves a shift in roles and business models for stakeholders active in this sector. However, barriers related to culture, regulations, market, technology and education are slowing down the transition.

The private and public sector need to create a level playing field in order for circular materials, products and services to become the new normal in the built environment. This requires bold leadership from both companies and policy-makers who have to transform the market (e.g. by introducing new valuation methods) and implement long-term policies that encourage the scaling of circular solutions (e.g. through circular procurement). Standardization, new forms of collaboration and co-creation processes are essential elements in the transition. Digital innovation, education and information sharing can further drive the change in mindset and culture that is needed to turn the circular built environment into reality.

Within the discussion on possible instruments that policy-makers can use to achieve waste collection targets and implement the 2015 Circular Economy Action Plan, deposit-refund systems (DRS) are often cited as a promising & useful policy tool. Such DRS ask consumers to pay an additional visible amount of money – a “deposit” – on top of the product price and then refund this money back if the consumer brings back the product (or its empty packaging) to an approved collection point.

In this report, ACR+ explored DRS experiences across ten European countries: Croatia, Denmark, Estonia, Finland, Germany, Iceland, Lithuania, the Netherlands, Norway and Sweden. Relying on available facts and data, the report presents an informative overview of existing examples and approaches in Europe for one-way beverage packaging. This analysis concludes that the launch timing in relation to other waste management systems and the positive participation of producers are both decisive in determining the success of the system.

Within the European project INCOVER, an experimental plant uses low-energy photobioreactors to cultivate micro-algae and transform wastewater into bioproducts.

This article describes this new experimental plant and the start-up stage, starting from the new design of three semi-closed horizontal photobioreactors with low energy requirements, for microalgae cultivation (30 m3 total), using agricultural runoff and urban wastewater as feedstock.

The inflow nutrients concentration is adjusted to select cyanobacteria, microalgae able to accumulate polyhydroxybutyrates, which can be used for bioplastics production. Part of the harvested biomass is used as substrate for anaerobic co-digestion (AcoD) with secondary sludge to obtain biogas. This biogas is then cleaned in an absorption column to reach methane concentration up to 99%. The digestate from the AcoD is further processed in sludge wetlands for stabilization and biofertilizer production.

On the other hand, treated water undergoes ultrafiltration and disinfection through a solar-driven process, then it is pumped through absorption materials to recover nutrients, and eventually applied in an agricultural field to grow energy crops by means of a smart irrigation system. This plant presents a sustainable approach for wastewater management, which can be seen as a resource recovery process, more than a waste treatment.

With an average of 79.5% recycled across Europe in 2016, steel for packaging is already the most recycled packaging material in Europe.

This report compiles examples of good practices from countries across the EU showcasing the varied projects, systems and processes by which steel for packaging is recycled, bringing significant reduction in emissions, resource and energy use.

Steel, a permanent material that can be infinitely recycled to make high quality products, can be easily sorted from the waste stream owing to its magnetic properties which make it the most economical packaging material to collect, sort and recycle over and over again.

Good practices in separate collection, sorting and recycling of steel for packaging contribute to improving its recycling rate, but can also serve as a guide for any stakeholder interested in improving these essential steps in a circular perspective.

The report provides a simple, yet rich overview of the barriers and enablers of circular economy business models as identifed by stakeholders, drawing upon a range of interviews, workshops and events, and a survey conducted with representatives of the European business sector.

Within businesses, stakeholders have identified high-level commitment accompanied by long-term perspectives, the personal drive and attitudes of staff, as well as the promise of enhanced competitiveness as key in supporting the transition towards circularity. Yet, from an internal company perspective, a number of factors were highlighted as getting in the way of the transition. Difficulties in financing new business models, taxation systems, resistance to change and the perceived lack of consumer demand are key examples of obstacles that hamper the circular transformation.

Importantly, stakeholders have provided interesting insights into possible solutions and recommendations able to overcome the challenges posed by circular economy barriers: tax incentives, the development of wealth-measurement systems other than GDP, material passports and quality standards, to name a few. Future solutions should also focus on ensuring safe areas for innovation out of tendering calls, green public procurement and increased financial support.
