Sustainable technology to recover toilet paper cellulose from sewage wins Aquatech Innovation Award 2017
‘Perfect example of the circular economy’ with practical use secures expert jury vote
The overall winner of the Aquatech Innovation Award 2017 was announced to a water sector audience on 30 October, with the top spot going to a Dutch technology that can recover toilet paper cellulose fibres at sewage treatment plants and produce a marketable cellulose product suitable for use in applications such as road construction.
“This is a very good example of resource recovery and is a perfect example of the circular economy in action,” commented Award jury chairman Prof. Cees Buisman, Scientific Director of Wetsus, a European centre of excellence for sustainable water technology.
A record number of entries
A record 78 entries were received for this year’s award across five categories. These had been narrowed down to 14 nominees by the independent expert jury for the overall prize. The winning entry, from company CirTec B.V., was then placed first in the category ‘Waste water treatment’ by the jury and secured the overall prize ahead of the winners of the other four categories.
The award was presented on the evening of 30 October at the opening ceremony for the Amsterdam International Water Week and Aquatech Amsterdam exhibition. This featured a keynote speech by Laura Tuck, Vice President for Sustainable Development at the World Bank, and a message from Mark Rutte, Prime Minister of the Netherlands.
Prime Minister Rutte highlighted the challenges the world faces if it is to meet the 2030 deadline of the UN Sustainable Development Goals. He pointed to the contribution made so far by the High Level Panel on Water. The road ahead, as he described it, is like trying to solve the Rubik’s Cube, and he underlined the Netherlands’ commitment both to the blue part and to solving the whole puzzle.
Environmental benefits and a usable product from the winning entry
The winning technology, named ‘Cellvation’, was developed in partnership with KNN Cellulose. The benefits cited include a reduction in energy and chemical costs for sewage treatment, along with a reduction in the amount of sludge that is produced. Cellulose is used as a technical product in applications such as road construction, offering an outlet for the marketable product derived from the Cellvation process. ‘It also means you have to cut down fewer trees, and the enormous amount of energy and chemicals that are used to convert a tree into cellulose can also all be saved,’ says Buisman.
Entries to the Aquatech Innovation Award are assessed against three criteria: innovation, feasibility, and sustainability. Cellvation scored highly against all three. In terms of feasibility, Buisman notes that two full-scale plants are in operation, and that use of the final product in road building has been demonstrated. ‘The whole chain has been shown, so we believe it is completely feasible,’ he says. ‘The innovation is that they have connected all these steps together, and not only taken the cellulose out of sewage, but processed it so it can be reused.’
