Coomtech Limited - Business Update

➢ Coomtech Limited is continuing development of all three of its drying technologies: ❑ SMR - now at market - continuing development ❑ TMR – in development (circa 18 months) ❑ IMR - in development (circa 36 months) ➢ We are raising funding in an A-Round for growth and are in the– expecting to close in Q2. ➢ Since last presenting at the UKQAA we are building commercial momentum: ❑ Plant 1: in ash processing for the cementitious industry in and around Greater

London and proposed for Thamesport on the Medway in Kent

❑ Plant 2: coal treatment plant in Australia – Latrobe Valley ❑ Plant 3: an ash plant in the USA

Coomtech Market Position

➢ Clarification of position – Coomtech is a technology provider - NOT ash sellers ➢ Building a plant at Thamesport however we will NOT own that plant ➢ Presently two financial institutions capable of “project funding” operating - vying for the build ➢ However it is of course our industrial demonstration plant and accessible to Coomtech:

❑ We want to be able to show SMR in operation ❑ We will be continuing to develop and of course overcome operational issues inevitably arising

➢ We are about facilitating partnerships for:

❑ In the Supply chain to clients ❑ For Off-take from clients ❑ Through cooperation's in engineering and process integration for clients

➢

Currently Fairport EPC guarantee the capability of a plant for throughput and aspects of operation

➢

Fairport are currently testing ashes utilised at Thamesport

➢

Recognising variances occurring from source to source, in moisture, particle distribution, characteristics and drying.

➢

Completion expected in May -19

Addition of moisture removal to the EPC wrap

Cement Plant Ash Handling

Coomtech SMR Process Status Summary

➢ Patent – International cover including Europe, USA, Canada, Australasia, India, Indonesia ➢ Market Readiness – plant approaching final designs for Thamesport mid year ➢ Trials – Fairport’s system is embarking on a series of longer runs at 50-300 tonnes on their design ➢ Scale – increasing capacity is a case of increasing modules of lines NOT increasing pipe size (Yet) ➢ Throughput – currently 1-1.5mtpa – subject to materials and moisture content ➢ Sizing – always targeting to process at <5mm for optimal performance ➢ Moisture removal – achievable down to 3% for blocks etc and below 0.5% for cement needs ➢ Manufacture – 80%+ of the plant is off the shelf

❑ Drying cartridges - have two UK manufacturing sources under Coomtech control

➢ Ongoing Development - for Thamesport and after for:

❑ Ash market ❑ Coal market ❑ Construction products

Post Processing Handling & Dispatch

➢ Energy – to create independent stand alone plant:

❑ Energy source LNG – supplier Molgas – provide full plant and service for contract life ❑ CHP Engine - supplied by Gruppo AB – Ecomax Engines ❑ Requirement – power to drive plant, adequate heat

production to maintain 800C in the process air at all times

Pre-processing Raw Materials & Stockpiling

➢ Target Sizing = <5mm ➢ On client/supplier site: ▪

Screened & Crushed to achieve <5mm by for transport wet by road, rail or ship - removing major hard conglomerates and foreign bodies

▪

Recognising wet ash responds to handling and transport – compacting / agglomerating

▪

Delivery to Coomtech site via tipper / sea vessel + clamshell grab & conveyors/ Samson style loader etc.

➢ Target Moisture = (Band to be agreed with client) 15-

20% at processing

➢ On Coomtech SMR site: ▪

Bulk stockpile (e.g. up to 40,000 at Thamesport)

▪

Magnetic detection

▪

Pre-processing storage at plant

▪

Final screen to <5mm

Feed Steps:

➢ Objective To Optimise 1 to1.5tph at material

specification

▪ Feed table supporting feed belts moving across lines ▪ Sweep the table in to lines via linked steep sided

hopper

▪ Above a rotary valve feeding product in to a air stream ▪ Objective for the air stream is to suspend the product ▪ Lean phase in the suspension section of each line ▪ At appropriate rate for line performance relative to

specification

▪ Air volume and air temperature ▪ Ready to enter the SMR Drying section

Drying Cartridge

(Uninsulated)

Inside Drying Cartridge: Plenum Chamber No Moving Parts Plenum Creates: Managed Turbulent Air Sheers Surface Moisture Off Particles Coomtech’s patented process uses turbulent air to remove moisture from the surface of particle (i.e. air drying of materials). Our patented process is called Surface Moisture Removal (“SMR”). Using air (as opposed to heat) maintains the mineral chemical composition and is lower in energy requirement.

Optimise water carrying capacity of air in process Particle time in process < 1 Second – at 800C = no time to dry

Coomtech SMR Plant Receiving Section

➢ Slow the product down ➢ Maintain separation of the particles and water ➢ Potential to manage particle distribution with cyclone ➢ Manage dry product to storage ➢ Take water vapor, aerosol and droplets to atmosphere ➢ Processed product at up to 5% moisture readily blown: ❑ To silo ❑ To road transport / tanker ❑ To rail transport tanker ❑ Direct to processing plant as feedstock

“Low Energy Low Cost Drying For Bulk Materials”

15

Post Processing Handling & Dispatch

➢ From the filters the ash, when dried to at 0.5

to3% total moisture can be blown to the next phase of handling.

➢ That may be: ❑ Direct to loaders for tanker transport ❑ To storage silo farm ❑ To dry condition storage bunker ❑ To process plant for immediate use ➢ Thamesport facilities are being designed to

hold up to 3 days production and to manage to split load types and therefore specific qualities etc to meet client demand -

➢ Primarily EN450 N targeted.

Capital Plant Costs Guidance

Based upon Thamesport:

➢ To run at 100,000 dry mtpa processing circa 120,000 ➢ Removing circa 15+% Total Moisture for 3% down to 0.5% ➢ Operating 24 hours - 7 days – 48 weeks (8064 hours pa) ➢ Stand-alone energy source CHP + LNG supply contract ➢ Inclusive of Coomtech SMR process plant and associated handling for process

storage £2.75 - £3.25m

➢ Design, procure, build and commission ➢ EPC performance underwritten contract ➢ Operating License and Maintenance support

17

Operating Costs Guidance

➢ Coomtech uses a proprietary model developed with the Wolfson Centre as a guide

for design.

➢ Variables to operate the plant:

• 1. Input moisture level
• 2. The volume of air through the plant
• 3. The maintenance of the air operating temperature to ensure water separation in the

process stream

• 4. External conditions

➢ Power is required to run the blowers & generate enough heat to maintain 800C in

process.

➢ Results depend on the materials but energy costs range from:

25% of the costs of thermal drying with gas To 40% of the cost of thermal drying with gas

➢ That can mean the Cost of operation including capex amortised over a contract life is

equivalent per tonne to the energy cost of thermal gas drying alone

Comparable Like for Like Cost per Tonne

NOTE:

➢ The following table is based upon published material and not specifically upon data for treatment of

Conditioned PFA – prepared 2018.

➢ The inputs include published capital costs, operating temperatures and energy use per wet tonne treated to

achieve a like for like with a common energy cost per KwHr driven by Natural Gas.

➢ The technologies suppliers are not named and the technology description if broad so undoubtedly other

suppliers in the category may provide better or worse results.

During the meeting on 30th April 2019 Coomtech were asked by the UKQAA Technical Committee for comparable data for thermal drying technologies – we have the following table:

Amortised over 5 year minimum contract Energy Costs

Scale & Future Plans

➢ Development will continue on current technology to:

❑ Improve throughout - reduce air volumes ❑ Improve moisture removal capability ❑ Reduce operating costs

➢ Increase in capacity of the individual line:

❑ Relatively small increase in diameter = large volume increase ❑ Relatively small increase in diameter = large increase in air
