• Drivers for growth are strengthening, especially relating to climate change and public accountability

Continuing trend for increasing regulation in high-hazard industries,

especially public service providers

Drives requirements for interpretation and response, business

integration,

performance improvement, cost-effective design of risk controls

Regulation

Increasing societal expectations on governance, accountability,

transparency, safety/environmental/social performance

Drives requirements for improvements in systems, processes,

organisations and culture

•One of the main aspect of sustainable development •= renewable energies.

•Renewable energies = renewed naturally, indefinitively, •et inexhaustbles at the temporal scale of our civilization

•Origines of renewable energies : Internal heat of the earth: geothermy Tide energy = interaction Earth - Moon Sun: photosynthesis: CO2 Biomass Biogas Energy + CO2

•Biomethanization Process •Natural phenomena = Degradation of organic matter by micro-organisms biogas containing methane 4 successive transformations : Hydrolysis Acidogenesis Acetogenesis Methanogenesis

1.Climat change

2.Oil reserves are

exhaustibles




- Anaerobic degradation of organic matter by micro-organisms

- 4 successive bioconversions steps :

1. Hydrolysis 2. Acidogenesis 3. Acétogenesis 4. Methanogenesis

- Hydrolysis & Acidogenesis = pH

- Methanogenesis : Optimal conditions

pH around 7 If pH < 6,5 : no CH4 T° between 35°C &40°C No oxygen No inhibitors

1 digester =

Completely stirred

Several dedicated digesters

= Multi stage technology




•Biomethanization – Natural phenomenon – Volta (1776) « Marsh gas is inflammable »

– Lavoisier (1787) « Hydrogenium carbonatum »

– Paddy field:100g methane / kg rice

– Animals (including ruminants): 110 millions tons methane /year

Biomethanization is one of the most promizing renewable energy offering a conversion rate of 4 to 5 TEP/ (year x ha) – (Source: Verstraet 2009)

Technology is now mature, after lots of efforts (complexity, legal environment, non captive use vs Bioethanol & Biodiesel)

– 40’ : biomethanization domestication and energy production by manure digestion

– Since 70’, 1st oil crisis & solution for manure issues

– 4200 plants in Germany + Integrated cases in Sweeden (Classical process)

– To Day: strong development (political will + economical and environment context)


Which substrates?

Biogas

1 Ton moist by-product

200 Kg Dried Matter

350 kg COD

230 Nm³ Biogaz

140 Nm³ CH4

140 Liters fuel = 1400 kWh

520 kWhé + 650 kWhth






The classical technology known as "completely stirred process” or CSTR: Digestion in a single tank organic material mixed with a fixed proportion of manure

required for the proper functioning of the plant Allows a maximum loads of 3 kg of organic matter / m³ / day

It works, but request manure and/or equivalent Risk of acidosis that stop the whole system for months Quite high operating costs Technology extremely sensible towards substrate changes


The GreenWatt technology combines : 1. Multi-stage technology: the liquefaction of solid waste (acid stage), the methanogenesis (pH neutral stage) and the post-digestion take place in separate dedicated digesters, which provides robustness, reliability, flexibility of use and optimum efficiency. 2. The HYFAD (High Yield Flushing Anaerobic Digestor): Unique high yield fixed bed methane digester design, integrating an automatized anti clogging system and biofilm renewal. 180m² /m³ of digester: 40 m3 = surface of 2 football pitches enable >30 kg COD conversion/m³.day

Which technology ?


Liquéfaction

acidogenesis





Stage 1 Liquefaction:

Transformation of by-products through the action of bacteria into a liquid rich in fatty acids: “acidic liquor”. Liquefaction requires a volume related to the type of input

Stage 2 Methanization HYFAD:

Production of methane gas by the action of methanogenic bacteria, by transforming the free fatty acids of the liquor coming from the liquefaction tank.

Optimal physico-chemical parameters are pH neutral & temperature around 38°C

Stage 3 post-digestion & gas storage :

Post-digestion and Biogas storage




The HYFAD is based on two tanks assembled on a metal structure before being installed on a concrete slab (Figure 1). The two tanks contain a kind of honeycomb on which the biofilm growth (Figure 2). The two tanks are connected with a set of valves that allows reaching high speeds of the liquid and proceed to the rinse of excess bacteria, therefore solving the problem of clogging (Figure 3). The system recreates, artificially and with low power consumption, the phenomenon of waves cleaning the coast and developing an optimal thickness of the bio-film The advantages of HYFAD are key : 1. Fully automated with low energy consumption 2. No risk of clogging the fixed bed digester 3. Optimal regulation of biofilm thickness and its exchange capacity that guaranty high yield and an extreme compacity




Key advantages of the multistage technology: 1.Possibility of treating organic substrates, without the use of livestock manure, allowing for use in

food industry sites 2.Sturdy self-regulating process that can cope with large variations in the quantity and quality of

substrate input without acidification of the digester. 3. Ergonomic and compact plant with reduced running costs. Can be decentralized and placed easily

on the waste production with short cycle not requesting any transport 4. Optimal regulation of the pH of methanogenesis reducing the duration of the process and allowing

for a quicker start-up time should the process be interrupted. 5. The HYFAD methanogenesis fixed bed digester renews the biofilm avoiding all clogging problems,

and guaranteeing optimal efficiency. 6. Improved biogas production yield through the optimisation of each stage of the bioconversion

process. 7. Flexibility of use, ability to adjust the gas production depending on the supply constrains

(availability of source materials) and the energy requirements. 8. Optimal digestate quality – 100% traceable origins. used or sell as a high quality fertilizer




For the treatment of sewage - liquid effluent with COD levels min 5.000mg/l, HYFAD technology or UASB

1. Smaller size of the plant and low operating cost allowing to be placed easily on the waste production site

2. HYFAD technology, allow optimal regulation of biofilm thickness and its exchange capacity, that guaranty high yield with no risk of clogging the fixed bed digester

3. Reduced time of the methanization process and faster recovery in case of an emergency stop

4. Flexibility of use; it is possible to regulate gas production according to the client specific needs
