SMART-Plant at the European Waterweek, Leeuwarden, September 22-27, 2018

SMART-Plant is joining the “European Water Tech Week Leeuwarden 2018” and will participate to a symposium on September 26th dedicated to “Recovered cellulose: from used toilet paper to resource for the biobased economy”.

Innovation, technology and policy leaders from companies, universities and governments get together during several inspiring events focused on the question how multidisciplinary cooperation can help to solve societal challenges around water. Issues like water scarcity, water pollution and water and health will be on the agenda, just like the water sector’s contribution to the circular economy.

Resource Recovery – Recovered cellulose: from used toilet paper to resource for the biobased economy

Recovery and reuse of raw materials such as cellulose from sewage has been on the agenda of water authorities, technology companies and end-users for many years. Should we reuse resources from sewage? Are we critical enough in the considerations? If we indeed want to recover resources from sewage, it’s time to change gears and speed up the process.

16.00 Opening and welcome by Coos Wessels, CTO CirTec

16.10 Applicability of cellulose in a circular economy, Prof. Dr. Bruce Jefferson

16.30 Critical comments on raw materials from sewage, to be confirmed

16.50 House of Commons debate, moderated by Prof. Dr. Bruce Jefferson

For this workshop we chose to use this form of debate to elicit a discussion in which all arguments about a predetermined statement will be discussed.

In the room, two rows of chairs are placed opposite each other, in between which the moderator/chairman can move freely. One side is in favour and the opposite side is against a predetermined statement. Who wants to contribute to the discussion has to stand up. Speaking is only allowed when the moderator gives you the floor. Each statement will have a short introduction by the moderator, followed by a discussion of max. 15 minutes.

In this workshop participants are encouraged to openly discuss different points of view. The aim is to create mutual understanding and get all barriers and arguments in the open. The format is as the House of Commons. The statements that will be discussed will be distributed the start of the debate and participants will randomly be asked to argue in favour or against a certain statement. Everyone should therefore be preparing himself or herself as a supporter or as an opponent of the statement. The fact that it doesn’t have to be the participant’s own opinion makes that participants can speak freely and get to think from a different angle.

SMART-Plant scales-up in real environment eco-innovative and energy-efficient solutions to renovate existing wastewater treatment plants and close the circular value chain by applying low-carbon techniques to recover materials that are otherwise lost.

Seven plus two (7+2) pilot systems were optimized for more than two years in real environment in five municipal water treatment plants, including also two post-processing facilities. The systems were automatized with the aim of optimizing wastewater treatment, resource recovery, energy-efficiency and reduction of greenhouse emissions. A comprehensive SMART portfolio comprising biopolymers, cellulose, fertilizers and intermediates were recovered and processed up to the final commercializable end-products.

Dynamic modeling and superstructure framework for decision support was developed and validated to identify the optimum SMART-Plant system integration options for recovered resources and technologies.

The integration of resource recovery assets to system wide asset management programs were evaluated in each site following the resource recovery paradigm for the wastewater treatment plant of the future, enabled through SMART-Plant solutions. The project proved the feasibility of circular management of urban wastewater and environmental sustainability of the systems, through Life Cycle Assessment and Life Cycle Costing approaches as well as the global benefit of the scaled-up water solutions.

Global market deployment was achieved as right fit solution for water utilities and relevant industrial stakeholders, considering the strategic implications of the resource recovery paradigm in case of both public and private water management. New public-private partnership models were also explored connecting the water sector to the chemical industry and its downstream segments such as the construction and agricultural sector, thus generating new opportunities for funding and potential public-private competition.
