Grootjes, A.J. (author), Kuipers, H. (author), van der Kooij, Y. (author), Wiermans, V. (author), Zwart, R.W.R. (author)The Dutch Water Authorities produce 1.3 million ton sewage sludge per year and the sludge disposal/treatment cost are between 115 – 250 M€ per year. There are opportunities under development to produce more renewable energy and raw materials from the sludges, lowering the sludge disposal/treatment cost. By doing so, the water authorities want to...report 2019

Grootjes, A.J. (author), Liakakou, E.T. (author), Boymans, E.H. (author), Zwart, R.W.R. (author)Biomass is a renewable feedstock that will contribute to the renewable energy goals of governments. Biomass is costly and therefore it should be used efficiently, creating maximum value, thus cascading is important, where besides energy products (electricity, heat, renewable gas and bio fuels) high value products like chemicals are produced. In...report 2019

Grootjes, A.J. (author), Vreugdenhil, B.J. (author), Zwart, R.W.R. (author), Energieonderzoek Centrum Nederland (author)Gasification is a thermochemical process which converts solid fuels into a gas with a useful heating value that can be further processed into a variety of products (heat, power, fuels and chemicals), thus creating smart market opportunities for the valorization of low-value solid feedstock. The feedstock composition and the gasification...conference paper 2016

(author), Rosillo-Calle, F. (author), Hensen, A. (author), Verheggen, B. (author)The report presents the results of the technical, economic and sustainability assessment of the import of torrefied bamboo pellets from Colombia to the Netherlands as a biomass supply chain for electricity production. The specific case assessment is for the bamboo species Guadua angustifolia. Additionally to guadua, alternative species (Guadua...report 2013

(author), Khodayari, R. (author)In this report the handling and storage facilities at several existing coal-fired power plants are described and critical logistic steps are identified when switching from coal to torrefied biomass. This information forms deliverable 6.1 of the project. For this deliverable input from EON, RWE and Vattenfall is mandatory.other 2012

Zwart, R.W.R. (author), Jungmeier, G. (author), Pucker, J. (author)In this paper, the greenhouse gas and energy balances of the production and use for space heating of substitute natural gas from biomass (bio-SNG) for space heat are analysed. These balances are compared to the use of natural gas and solid biomass as wood chips to provide the same service. The reduction of the greenhouse gas emissions (CO2-eq.)...article 2012
