Project partners

This project is a collaboration of three parties.

Hoogheemraadschap Hollands Noorderkwartier

logo_hhnk.jpgThe Hoogheemraadschap Hollands Noorderkwartier (HHNK) is responsible for dikes, water and roads in an area that covers most of the Noord-Holland province.

HHNK's core business consists of:

  • Dikes: protecting people from floods;
  • Water: to ensure adequate and clean surface;
  • Roads: the management and maintenance of rural roads.

One of our main tasks is purification of wastewater. We do this with the help of 15 wastewater treatment plants (WWTPs), which together treat more than 100 million m3 of wastewater every year. This huge amount of wastewater is partly derived from households and businesses connected to the sewerage system. The other part consists of rainwater that enters the sewer system. The treated water flows back to the surface water.

Attero is one of the market leaders in the Netherlands when it comes to the treatment of household waste. The starting point is the recovery of raw materials and the production of renewable energy from waste. As an innovative company Attero wants to expand its activities with i.a. the processing of organic streams to high-quality raw materials, with the aim to create maximum value from waste in general and in this case specifically from organic waste following the Biobased Value Pyramid.

Attero carries out many innovative projects developping bio-based technologies and products (production of PHA bioplastics and proteins from organic waste and fly larvae; construction materials from cellulosic streams; green chemicals from organic waste; bio-LNG from organic waste; high quality fertilizers and compost from organic waste products). Specifically, a lot of experience with the production of plastics from a self-developed two-stage fermentation process in Venlo.

The experience, knowledge and expertise in the field of waste management and the knowledge gained from the innovative biobased projects listed Attero make the perfect partner in this project. The contribution of Attero to this project is focused on the research and development of the enzymatic degradation of cellulose and PLA production from the point that the suspended solids are separated from the influent. Additionally Attero wants to further investigate the marketing of sugar water and PLA. As there will be also a product that must be demanded by the market has developed.
