Bio-filters 3

▪ Methane extraction system

▪ Landfills need more than 350,000 tonnes of waste in place (tWIP) to create enough methane to be economic

▪ Vertical wells that inject air and moisture to create an aerobic environment for rapid decomposition

▪ Landfills need more than 250,000 tWIP to have enough carbon offset revenue to be economic

▪ A filter that covers emission “hot spots” and converts

the methane to carbon dioxide

▪ Smaller landfills can make use of this relatively inexpensive technology to generate offsets

Landfill Gas A landfill is an a anaerobic digester releasing methane

gas over time from decomposing organics.

Landfill gas comprised of methane, carbon dioxide and trace gases. Methane concentrations in landfill gas 50% - 60%.

Methane is a GHG and has 21x the global warming potential of carbon dioxide.

28

Salmon Arm Landfill Properties Phase I closure conducted in 2010- 2011

2007 Gas Utilization Opportunities Assessment Preferred Option LFG to pipeline quality biomethane

2008 Phase I Closure Plan and Phase II Upgrade Closure design

Self Managed Project: employed over 20 local contractors on project and created ongoing employment maintenance and upkeep.

Geomembrane cap to maximize gas collection efficiencies. 3Ha closure of 350,000 tonnes of waste.

Gas collection efficiencies designed to exceed 75%. Leachate re-circulation from phase 2 development. Phytoremediation of leachate using hybrid poplar. Total Budget Estimate 3.85 M Active Gas Collection to Flare component 1.O M

29

Landfill Gas Collection

Horizontal collection Vertical Collection Under Vacuum to a Flare

31

Phase II Leachate / Gas Collection Phase II engineered with basal liner to collect and

treat leachate to be injected into phase I waste.

Phase II will re-circulate leachate as a bio-reactor to speed up anaerobic breakdown which increases gas flows.

Excess leachate used to spray irrigate hybrid poplar plantation.

32

Hybrid Poplar Plantation

33

Economic & Environmental Considerations Landfill Closure System $2.85 Million

Reserve Account Contribution – no tax implications LFG Collection system $1 million Annual operations $60,000 No funding mechanism

Approached Terasen Gas to determine interest in landfill gas upgrade project.

Resulting 15 year agreement. Terasen to fund all upgrades needed. Subject to BCUC approval.

Terasen to compensate the CSRD through purchase of raw gas. Funding anticipated to cover operating costs only, not return on capital. CSRD to retain available carbon credits.

Carbon credit funding required for economic viability.

34

Landfill Gas Regulation Landfill Gas Regulation - January 2010

All landfills accepting 10,000 tonnes per year or with 100,000 tonnes in place are regulated

If regulated a generation assessment is to be performed (every 5 years). First year of assessment 2011.

When assessment shows methane gas production of 1000 tonnes per year or greater, an active gas collection system is required in 5 years from assessment date.

Salmon Arm landfill expected to exceed threshold in about 2020. Expected to be picked up in 2021 assessment.

Active system required in 2026.

With project commission in 2011: 15 years of credit acquisition opportunity before regulated.

35

Pacific Carbon Trust CSRD approached PCT through expression of interest

call.

PCT workshops/discussions on process, steps/stages required.

Negotiated agreement for the sale of offset credits.

2 year agreement with optional renewals to 2020 (or when regulated).

36

Points of Note on Project NPV (15 years) of $0 (based on moderate organic

diversion)

Factored in operations and capital

Revenue from sale of raw gas to Terasen: $300,000

Revenue from GHG sales (2011 – 2026): $1,500,000

Remove over 110,000 tonnes of CO2e

37

Other Opportunities at Rural Sites

Biofilter & Biocover

Methanotrophic bacteria oxidize methane that fugitively passes through landfill soil cover.

Biofilter/biocover media technology ensures fabricated soil is optimized for methanotrophic bacteria optimization.

Pilot projects have been initiated in a few areas in B.C.: TNRD, CSRD, and EKRD.

CSRD initiative reallocates passive methane vents into bunkers containing biofilter.

Currently no protocol exists, but with enough interest and data – a protocol could be developed.

38

Skimikin Landfill Biofilter • In 2005 the CSRD closed and capped this landfill installed passive vents. • In 2011 the passive vents were re-routed into a biofilter. University of Calgary post

graduates contribute to monitoring program. • Measurements of gas flow and composition into the biofilter. Measurements of

Biofilter temperature, moisture content and methane flux. • Considerations of other methane oxidation techniques such as carbon isotope

measurements

Methodology - Measurements

• Thermocouple sensors used to measure temperature

• Gas samples were collected using tubing and analyzed for O2,

N2, CO2 and CH4

• Time Domain Reflectometry (TDR) sensors used to measure

moisture

• LFG surface emissions measured using a static flux chamber

method

• Monthly monitoring events over 15 months

TNRD Plans

• Active landfills being closed by the TNRD – 2012 to 2013 –

Methane oxidation beds (MOBs) size and number based on

surface scans done by AITF at the sites in 2011:

– Barriere landfill – will use three 20mX20m MOBs, Landfill area

= 2.7 ha

– Clearwater landfill – will use five 20mX20m MOBs, Total

landfill area = 1.5 ha

– Chase landfill – will use three 20mX20m beds, Total landfill

area = 3.1 ha

• At each landfill 2 MOBs will be instrumented to provide critical

data on MOB methane attenuation efficiency for use in

establishing a protocol for GHG reduction and potentially carbon

credits through PCT

64

TNRD Plans

• In addition the TNRD has about 30 previously closed

landfills that will be scanned for methane production

and MOBs will be installed at site where warranted. So

far the closed landfills at Clinton, Logan Lake and

Lytton have been scanned by AITF and it is likely that

MOB installation will be recommended for the Logan

Lake landfill

• With the assistance and training of AITF, the TNRD

intends to use its own staff to continue with the surface

scans, MOB installation and monitoring of

instrumented sites and provide data for analysis by

AITF

65

Limitations of Methane

Oxidation Technology

• LFG generation is high enough to sustain

collection, flaring, or utilization

• Remaining LFG emissions are very low -

low methane generation potential in waste

• Compost and/or biosolids supply is limited

to use for biological active methane

oxidation layers

66

Opportunities for Using Methane

Oxidation in Canadian Landfills

• Landfills where LFG utilization is not

economically sound – low LFG

generation rates

• Small Landfills where LFG collection and

utilization is not economically viable

Discussion/Questions

69

Are you now aware of carbon reduction

opportunities in your community?

Does your community have a landfill methane

management plan?

Does your community have any organic diversion

projects in place?
