Ad Lansink received two honorable invitations for visits and presentations outside the Netherlands, respectively from IMWSA (South Africa) and from ISWA, in relation to the ISWA World Congress 2018 at Kuala Lumpur. In both cases, the recent publication of his book Challenging Changes – Connecting Waste Hierarchy and Circular Economy is the actual reason for the invitation.

Johannesburg  (South Africa) 15 – 19 October 2018
The Institute of Waste Management of Southern Africa invited Ad Lansink taking part on the 24th WasteCon™ flagship Conference and Exhibition on 15-19 October 2018. The theme of the conference will be ‘Implementing the Waste Hierarchy. This showcase of best practice African waste management solutions will take place at Emperor’s Palace in Johannesburg. Waste management in South Africa is guided by the internationally accepted waste management hierarchy, which is implemented through the National Environmental Management Waste Act (2008). During the plenary session on 16 October 2018, Ad Lansink will held the keynote adress about Challenging Changes – Connecting Waste Hierarchy and Circular Economy. The waste management hierarchy aims to extract the maximum practical benefits from products and to generate the minimum amount of waste. Proper application of the waste hierarchy has several benefits, helping prevent emissions of greenhouse gases, reducing pollutants, saving energy, conserving resources, creating jobs and stimulating development of green technologies. During the conference and the exhibition, Ad Lansink will be present to speak with delegates. Signed copies of Challenging Changes will be available for delegates, who are interested in the implementation of the waste hierarchy and the transition to circular economy.
