3 Pillar Strategy

Hydrothermal Carbonisation - HTC

Biomass (DMC 20-30%)

Carbonisation

Hydrolysis

HTC Biocoal (DMC 70-95%)

Polymerisation

HHV of 12-32 MJ/Kg


Some examples of well suited biomass (cellulose, hemi-cellulose, protein) Spent grains from breweries

Wet cake from bio ethanol production

Empty fruit bunches (EFB) from palm oil industry

Manure

Digestate from Biogas University Hohenheim

Why Focus on Waste Water Sewage Sludge?


Wir werden die Klärschlammausbringung zu Düngezwecken beenden und Phosphor und andere Nährstoffe zurückgewinnen. Koalitionsvertrag zwischen CDU, CSU und SPD 18. Legislaturperiode

Das Bundesumweltministerium will Regelungen zur Phosphor-rückgewinnung zügig voranbringen. „Der Koalitionsvertrag sieht vor, dass Phosphor und andere Nährstoffe zurückgewonnen werden sollen. Dies werden wir so schnell wie möglich umsetzen“, Parlamentarischer Staatssekretär im BMBU Florian Pronold (SPD), Zweiten Europäischen Konferenz zur Phosphorbewirtschaftung in Berlin.

Nach einer Übergangsfrist soll der Phosphor in phosphorreichen Abfällen wie Klärschlamm, Tier- und Knochenmehl ab 2016 nach dem Stand der Technik zurückgewonnen werden. Die Pflicht zur Phosphor-Rückgewinnung soll 5 Jahre nach Inkrafttreten der Verordnung gelten. Revision TVA, Schweiz

Die Europäische Kommission hat Phosphatgestein auf die Liste der kritischen Rohstoffe aufgenommen. Europäische Kommission Pressemitteilung 26.5.2014


Waste Water Sewage Sludge is a problem in Europe and is available in large quantities (12 Mio. tons dry matter)

Clear trend from land fill and agriculture application towards thermal use (due to ecological and cost reasons)

HTC saves over 50% on thermal and electrical energy compared to existing thermal drying technologies (ZHAW Study)

HTC has best life cycle analysis results compared to other technologies (ZHAW Study)

HTC is less capital intensive than mono incineration and therefore helps save money for the communities

Due to the phosphorous recovery process “AVA cleanphos” HTC Coal from waste water sewage sludge can in the future still be used in co-firing and therefore reduce CO2-emissions

Efficient phosphorous recovery with “AVA cleanphos”

8 Lessons learned

1. Technical capability does not automatically mean commercial success

2. Current EU-Waste hierarchy does not support the most efficient or commercially interesting technologies and prevents efficient biomass for energy solutions to be implemented

3. End of Waste can play an important role in biomass to energy projects

4. Size does matter – economies of scale play an important role for biomass to energy technologies

5. Co-location is a critical aspect for HTC

6. Regional biomass development strategies are critical for an efficient biomass use

7. Clear government regulations are a must. Uncertainty scare away private investors

8. And finally: New technologies (such as HTC) need financial government support for the implementation of first flagship projects.
