BioFest 2016:

Vegetation’s Value in the Biosolids

Investment Equation


Today’s Trip to the Bank

Can green do more?

• What is biosolids value?

• Can the vegetation investment recover

cost?

• Core business vs. vertical integration

• What the Alberta willow demonstrations are

teaching

• What does the next step in cost recovery

look like?


The Almighty Dollar

Estimating the material value of biosolids

• Urea $260/T; DAP $360/T

• N (2-6%); P (0.5-1%); K (0.1%); Micros

• Organic Matter

• Biosolids Value $35-$70/Tonne.

But true value is what the

market will pay.


Potential…

Biosolids

• Nutrients and organic matter

• Improves soil tilth

• Reclaims productivity in marginal soils

• A true environmental superhero

• Everyone will see this

• Everyone will want some

• Demand will outstrip supply

• Biosolids will generate revenue.


…Unfulfilled

Value recovery is rare

• Production, transport, application

• Markets, demand immature, competition

• Supply oustrips demand

• Managed at a cost.

Benefits universally realized…

…are we too diverse?


(sub)Vert the Process

Find a new value proposition

• Vegetation that meets a need

• Value that must already be realized?

• Vertical integration

• Highest and best end use for generations

One that is:

• financially palatable

• financially profitable?


Alberta Vegetative Value

What is its value?

To achieve

• Feedstock for compost

• Soil improvement

• Carbon sequestration

We will use

• Biosolids

• Marginal farmland (brown chernozems)

• Short Rotation Willow


Green Investment - Willow


Value – Environmental Services

Productive fallow for marginal soil

• Agricultural rest

• Biosolids and willow roots - OM

• Litter - OM

• Diversification – visual,

environmental

• Windbreak

• Improve marginal soils

• Improve long term arability


Value - Carbon

Biosolids produces high-C feedstock

Verification in process!!!


Municipal Compost Feedstock

The willow has internal value

• Feedstock for new composter

• stable, consistent, reliable

• Biomass to compost biosolids

• Be financially profitable

• Achieve highest and best end

use

• Be relevant to as many people in

as many places as possible.


Repeat


Feedstock Value Challenge

Other highest best use?

• Livestock bedding for CAFO’s?

• Chips for biomass energy?

• Biocoal?

• Biochar? activated carbon?


Anecdotal Value

Compost Feedstock

• Up to $30/tonne; Potential 10 year agreement

Bulk Livestock Bedding

• $60-$150 per tonne ($2/cuft); Light drying/storage required.

Biomass Energy and Biocoal Feedstock

• $30-$100/tonne; Drying required (torrefaction for Biocoal).

Biochar (reclamation and amendment)

• Up to $450/tonne; Pyrolysis required


Achieve Max Value

…but without the wrinkles?


A Need Identified

Excess lagooned biosolids targeted for use


A Need Addresses a Need

Enhance Alberta’s prairie coal mine reclamation

with biosolids.


The Green Investment


Multiple End Uses

Harvest the Willow at 3-year intervals for:

• Planting stock

• Soil carbon amendment

• Energy feedstock (biocoal)


REPEAT.
