Let’s not our


THE SITUATION – ORGANIC WASTE

• 9,000,000 tonnes of organic waste generated in Ontario annually

• 25% to 40% of all food is wasted

• 1/3 of our total waste stream is organic

• Majority of waste currently is landfilled

• Organic waste management is an environmental challenge


THE SOLUTION:• Renewable energy through Anaerobic Digestion

• Seacliff Energy processes 30,000 tonnes of organics annually

Electricity production powers ~1200 homes

Thermal power to heat 6.5 acres of greenhouses

By product of nutrients is fertilizer for 2,000 acres of corn

• Ontario could host 300 ADs,

electricity for 360,000 homes,

nutrients for over 500,000 acres of corn,

heat for 1,600 acres of greenhouses

What is Anaerobic Digestion

Anaerobic digestion is a series of processes in which micro-organisms break down organics materials in the absence of

oxygen. It is used for industrial or domestic purposes to manage waste and / or to

release energy .

ANAEROBIC DIGESTION• Biogas was used for heating bath water in 10th century BC in

Assyria

• Pasteur proposed utilization of biogas

• Biogas was used to light lamps in UK in 1890s

• Seacliff uses a 2 stage digester that splits fermentation biology

• First 2 stages of fermentation are hydrolysis & acidogenesis

• Last 2 stages of fermentation are acetogenesis & methanogenesis


THE PROJECT • Began in 2005 as a solution for alternative energy for greenhouse

• RESOP in 2008 enabled AD viability

• Site preparation in 2009

• Project delayed due to moving target of permit

• Construction resumed in 2010 – tornado setback

• First KwH produced January, 2011

• Separation equipment installed in January, 2012

June 2, 2010 – 4 days before Tornado

Structural damage at Seacliff Energy - aftermath of June 6/10 tornado

June 6/10 – Tornado touches down in Leamington area - severe damage at both Pelee Hydroponics and Seacliff Energy

THE PROCESS• Incoming organics unloaded in enclosed building

• Solids on the floor, liquids in sealed storage tanks

• Grocery waste and slurries in receiving pit

• 80 tonnes of waste introduced daily into pre-treatment tank

• After 24 hrs of pre-treatment tank is pumped into one of 2 holding tanks

• From pre-treatment tanks, slurry is fed to both fermenters every 15 minutes

• All tanks stirred at preset intervals

• Fermenters are kept at a constant fill level – 24,000 gals of nutrient rich

digestate is removed


INPUTS:

• Liquid & solid organics – everything from food processing waste

to grocery store organics

• Most organics are contaminated with plastics, wood, glass, etc.

• Seacliff has installed state of the art separation equipment to

remove contaminants

• Landfill reduction of 90% - 95% for grocery store organics

Acceptable Waste Products for Digester

Liquid Products Solid Products * Syrups * Organics * Daf Sludge’s * Vegetables * Carbonated drinks * Fruits * Chocolate * Meats * Cooking greases * Flowers


METHANE PRODUCTION• 750 cubic meters of biogas generated hourly

• Enough gas to produce 1600 KwH of electricity

1KwH of electricity = 1 KwH of thermal power produced by engine

• Heat is recovered from stack & engine oil cooling through heat exchangers

• Heat is stored as hot water in 2 million litre tank

• Heat is directed to digester process or greenhouse as required


SOCIO ECONOMIC BENEFITS OF AD• Reflects Green Energy Act mandate

• Organic waste management through renewable energy production

• Jobs – 5 fulltime jobs created - 15 additional direct jobs

• Sustainable base-load power

• Produce power where needed & avoid high transportation losses

• Infrastructure benefit to consumers

• GHG reduction

• Fossil fuel reduction

• Landfill reduction – groundwater protection

• Biogas plants cost 75% less than indoor composting

BARRIERS TO BIOGAS IN ONTARIO/CANADA• NO national/provincial biogas strategy

• Access to grid restricted

• Price

• NIMBYism

• Landfill costs still inexpensive

Respect for the interdependence of all existence of which we are a part.

What can you do?• Google www.biogasassociation for more information

• Write your MP, MPP, Municipal Councilors

• Continue to reduce, reuse, recycle

What does the future hold?• Status of biogas in Europe

• Opportunity for Ontario

• Seacliff’s role in promoting biogas

• Biogas is a stepping stone to an

evolving,

sustainable,

renewable

• energy solution to the replacement of fossils fuels
