Waste Management 2030+

This is an article I prepared for the magazine Waste Management World. It is based on my key-note lecture at ISWA´s conference in Lisbon, October 2009.

The purpose of the article is to outline the major trends and challenges that will shape the future of waste management for the next few decades. Although in our complex and unpredictable world ‘prediction is very difficult, especially about the future’ (Niels Bohr), there are certain trends and facts that more or less create the ‘bigger picture’ in which the waste management industry will evolve. Interestingly, discussion of these trends has not up till now directly linked them with waste management – at least not according to the author’s knowledge.

Putting these trends together and considering the consequences they will have for waste management, it is clear that new challenges are emerging, and the current situation must be seen in a different way. Our waste management systems and our market conditions, even at their best, are incapable of handling the growing amounts of waste globally. So unless a new paradigm of global cooperation and governance is adopted, a tsunami of uncontrolled dumpsites will be the prevailing waste management method, especially in Asia.

ABRELPE is getting recognized as a key-stakeholder in Brazil

With great pleasure I visited Brazil once more, as an invited key-note speaker for ABRELPE´s seminar on waste management technologies.

Every time I come to Brazil I feel a vibrating country, people with great expectations and hopes, a booming market and a growing waste management sector. The last is certainly reflected to the great participation and publicity ABRELPE´s events have gained, with new records achieved year by year.

This time, the event organized was dedicated to the new waste management policy, a real revolutionary approach and one of the most progressive waste management laws worldwide. Reverse logistics, shared responsibility during the product life cycle, a waste hierarchy approach and integrated waste management plans countrywide are just some of the key - points that have already started to be discussed in Brazil.

The event was a big success and ABRELPE utilize it in order to present the unique publication PANORAMA 2010, which includes a detailed presentation of waste management activities in brazil and their benchmarking year by year. It also includes a summary in English and Spanish, so it is pretty useful for anyone who is interesting in Brazilian situaton regarding waste management. The whole publication can be found at:


PANORAMA 2010 and the whole event were covered with great publicity. frankly, it seems that Carlos Silva Filho, ABRELPE´s managing director has gone a long way forward and now ABRELPE is not just a well placed stakeholder within waste management community - it is becoming the key-stakeholder and the main reference for waste management activities in the country. Congratulations Carlos and I wish ISWA to have more members like ABRELPE.

Needless to say that the Brazilian hospitality was as always great, which makes me again waiting for the next opportunity to visit Brazil.


Sustainable landfill concepts from a practicioner's view

Megacities and waste management: A challenge for 21st century

This is a paper presented at th recent ISWA Conference in Hamburg, November 2010.

Its purpose is to present the challenge of waste management for the emerging megacities of the developing world and transition countries and to outline major issues that have to be further elaborated in order to create sustainable patterns in waste management.

Megacities face tremendous environmental challenges and threats for human health. In this framework the role of waste management is becoming more and more crucial both for the daily life as well as for the long to medium term sustainability of megacities. The challenge of a successful waste management in megacities is one of the most demanding for public authorities and the waste management industry.

This paper outlines some of the major characteristics of megacities that substantially affect waste management activities like their rapid growth, the symbiosis of wealth and poverty, the role informal economy, governmental and institutional issues and their major role in the globalization process.

Then it focuses on how the characteristics of megacities create certain conditions and implications for waste management depending on the megacity growth profile.
Special importance is given to the role of the informal sector and the experiences related its integration to waste management systems. While there is no certain way for a successful waste management approach, there are things that must be avoided and they are presented in a Failure Receipt. Also, some generic suggestions are made on how to increase the possibilities of a successful approach.

Finally, it is proposed a view and certain questions that must be answered in order to understand how sustainable waste management can be created within the triangle megacities – globalization – waste management.
