Last years have seen a surge of Industrial Symbiosis (IS) development in association with ad-hoc widespread policies to encourage more circular and sustainable practices in the manufacturing sector. Developments in Europe, despite having attracted less attention in the literature, have been significant, driven both by public and private initiative. This paper provides an updated overview of IS activity in Europe, with a mapping of key networks, and a study of prevailing typologies of networks, size, geographical distribution and main streams/ resources traded. The analysis is based on a combination of desk research, gathering of primary data from case studies, a survey to IS network facilitators (n=22) and in-depth interviews and focus groups (3) with IS practitioners, policy officers and industry representatives (n=25). The analysis identified pockets of IS activity across all Europe, although varying in nature, resources exchanged and scale and scope of the initiatives. The average size of the mapped networks is approx. 473 members, but the median is approx. 100 members, which indicates high variability of sizes. The geographical scope of the synergies also seems to be dependent upon the following factors: 1) the type of waste stream/by-product; 2) transport costs and 3) market value of secondary materials. Types of waste streams exchanged common to most networks, are chemicals (e.g. chemical base products), biomass and agriculture by-products, wood and wood pellets, plastics, reusable construction materials, equipment, inert waste and water (different qualities including industrial water), residual heat and steam. The paper also discusses key obstacles facing IS development in Europe highlighting: 1) weakness of economic incentives given the low margin of IS projects associated to undeveloped secondary markets; 2) geographical variation of incentives and drivers, given differences in policy frameworks and support mechanisms (e.g. landfill tax levels) and 3) legislative issues that make transport over geographic boundaries extremely complex and administratively burdensome. Finally, the paper concludes with a general discussion of the potential of IS to contribute to the transition to the circular economy (CE) in Europe and identifies some key areas of future research.

The Clean Development Mechanism (CDM) is one of the three greenhouse gas emission reduction and trading instruments of the Kyoto Protocol (KP). The CDM allows governments and business entities from developed countries to offset their emissions liabilities by reducing or avoiding emissions in developing countries, where it is often cheaper to do so. Examples of CDM projects include the installation of various renewable energy producing facilities, cutting the GHG emissions in industry and waste management, or projects focused on improving energy efficiency. From the sustainable development perspectives CDM has been alleged as a new channel of transfer and diffusion of climate friendly technologies (CFT) in developing countries. However we are evidencing that the majority of the CDM projects deploy local sources of technology, which challenges the NorthSouth technology transfer paradigm established under the sustainable development agenda of the KP. This paper is an attempt to explain technology sourcing patterns in CDM projects through employment of knowledge base determinants. On the basis of an empirical analysis we conclude that in countries with a stronger knowledge base in CFT, CDM project implementers tend to go for local and combined technologies and less for foreign technologies.

Technology transfer in Clean Development Mechanism (CDM) projects of the Kyoto Protocol has become one of the important issues addressed both in policy agenda and by academic scholars. In many CDM project host countries, technology transfer is among the key provisions of sustainable development objectives of the CDM projects. This study is an effort to investigate CDM projects' related technology transfer process from the organizational learning perspective. The prerequisite for successful technology transfer and organizational technological learning is to foster technological capabilities (TC) of an organization. In this study we used data from our survey of the CDM project host organizations in four largest CDM host countries India, Brazil, Mexico and China. We assessed TC building progress and studied various characteristics of the organizations. The present paper focuses on absorptive capacity related determinants of technological capability building in the CDM projects. Absorptive capacity is a multidimensional concept thus we investigated the effect of the dimensions such as prior knowledge, personnel qualification, and training efforts. A strong positive association was established between prior knowledge and TC building; and less for qualification variable. Besides we proved a curvilinear relationship between prior knowledge and TC building outcomes. *Corresponding author , Technopolis Consulting Group Belgium Sprl, 12, av. de Tervuren, 1040, Brussels, Belgium, E-Mail: asel.doranova@technopolis-group.com **United Nations University -MERIT, Keizer Karelplein 19, 6211TC, Maastricht, the Netherlands, E-mail: ionara.da.costa@gmail.com ***Eindhoven University of Technology and Tilburg University, Brabant Center of Entrepreneurship, P.O.
