10:40 – 10:50

Stimulating innovation in the chemical sector

An Maes, essenscia

10:50 – 11:05

Learning network on water: initial findings

Steven Raes, Sweco

Water is a crucial factor in the production process for the chemical and life sciences sector. That's why essenscia is starting a 'Water Learning Network'. This initiative should help sector companies save and reuse more water. Among other things, practical examples from the sector were presented, as well as the companies' savings potential.

11:05 – 11:15

New subsidy opportunities

Joachim Castelain, Flanders Innovation & Entrepreneurship

Flanders Innovation & Entrepreneurship will give a short presentation about some new subsidy possibilities that will be launched.

11:15 – 11:30

Circular water concept at Dow Terneuzen

Dion van Oirschot (Rietland), Niels Groot (Dow)

Dow Terneuzen intends to go 100% circular for their water consumption and aims for complete independence from the drinking water network and from the intake of surface water. One of the key issues here is the upgrading of treated waste water back to process water for the Dow plant. Rietland provides post-purification in an aerated reed field in the purification train.

11:30 – 11:45

Potential reuse of treated waste water in the chemical industry

Dries De Cock, Epas International

Screening of potential reuse as process water of effluent water from the wastewater treatment plant of a company in the chemical industry by means of lab-scale tests. With this, a distinction was made between the combination 1) MBR/RO, 2) MBR/active carbon/RO, 3) UF/RO installation on the effluent water of the existing biological treatment.

11:45 – 12:00


Parallel session 1: and essenscia

12:00 – 12:15

Eastman: Raising awareness in a company

Karl Gyssels, Eastman

The first step in sustainable water consumption at Eastman Ghent North was to make all employees involved more aware of water consumption. By doing this and by setting up a very simple monitoring system at the same time, a spectacular reduction in water consumption was achieved.

12:15 – 12:30

Janssen Pharmaceutica: drainage water as process water

Dirk Reyntjes, Janssen Pharmaceutica Beerse

During the winter months, the demand for RO water for boiler feed for industrial steam is relatively high. In the past, this feed water was created with softened drinking water. In this case, we have used the "surplus of greywater during winter" to reduce the purchase of potable water and, in addition, to increase the proportion of reuse of rainwater on an annual basis.

12:30 – 12:45

Water saving initiatives from Molymet Belgium: closed cooling water system

Nele Van Roey, Molymet

Initiatives taken by Molymet around the topic of water scarcity (water audit, water integration study for new Purox department,... Learning Network Water essencia)

12:45 – 13:00

Agfa Gevaert: Using rainwater as an alternative to groundwater

Marc Hofman, Agfa Gevaert


Agfa Gevaert is looking at using rainwater instead of groundwater as process water. In doing so, they are appealing to some of their neighbours in a pilot drought project.

13:00 – 14:00

Sandwich lunch at the stand

Parallel session 2: VMx

12:00 – 13:00

Update of legislation and regulations on water in the chemical industry

Evert Vercauteren en Arne Braems, Sertius

Water Expert

An overview is given of important changes in legislation and regulations concerning water in the chemical industry. Relevant BREFs for the chemical industry will be discussed, as well as the new assessment framework for discharges of industrial wastewater. It also looks at the field of tension between water saving on the one hand and standardisation on the other hand in the case of water reuse and/or the use of high-tech purification technology.

13:00 – 14:00

Sandwich lunch at the stand (TNAV) is a Flemish federation of water technology companies. Our organisation creates a platform where Flanders ‘academia‘ and ‘industry‘ meet to broaden their viewpoint on the local and global water industry.

VMx vzw is the professional association for all environmental professionals (environmental coordinators, environmental experts, EIA experts, ...). The core tasks of this member association with nearly 900 members are: advocacy, information provision, continuous training and networking.

essenscia is the Belgian sector federation of the chemical industry and the life sciences. The organization represents the specific interests of companies active in chemistry, plastics, pharmaceuticals and biotech.
