The Drivers – The Need & the Opportunity
In the face of the related global agendas of:
–
Climate change;
–
Resource depletion, and the need to establish
–
Sustainable economic systems;
a definitive conclusion is the need to limit the use of
fossil fuel resources and so to reduce Greenhouse Gas
accumulation in the atmosphere.
–
The only logical source of supply for carbon based
molecules in a resource depleted and carbon
constrained future.
–
The original source of the “solar powered”
conversion of atmospheric carbon(CO
2
) into
vegetative biomass – the original source of fossil
fuels – that we are being discouraged to use.
–
“Waste” biomass – no longer the “ugly ducking”.
Biomass Comes of Age
Essential Biobased Products
Modern complex economies cannot operate without the carbon
based molecules currently supplied by fossil resources, for the
full range of uses and “drop in” alternatives, including:
–
The complete range of chemicals and products from the
integrated petrochemical sector;
–
Coke/coal/reductant materials that are essential for the
metals manufacturing/smelting sector;
–
The agricultural fertilizer/soil productivity sector; and
–
Specialised and liquid transport fuels sector, with special
focus on aviation fuels.
NB
: More than just compost or firewood. Bioenergy as an
important
by-product
.
Biomass currently presents as 5 generic sources (defined by commercial
circumstances at point of presentation):
1.
Forestry and Agricultural
harvest
residues
– Characteristics: seasonal
or campaign availability but homogeneous by-product of core activity.
2.
Forestry and Agricultural
processing
residues
– Characteristics:
regularly available, homogenous and geographically concentrated but
a supply pushed by-product.
3.
Urban waste streams
– Characteristics: end of (first) life arisings to be
recovered as reliable, but heterogeneous flows via
streaming/cascading systems.
4.
Land Management & Development Arisings
– Characteristics: one off
or irregular arisings of potentially high value homogeneous biomass.
5.
Specially grown or generated biomass
– Characteristics: highest
quality, reliably available but most expensive as primary production
costs to be recovered in sale of materials. Needs cost effective outlet
for by-products.

over time
Highest Net Resource Application of Available Biomass
Table 1: Comparison of benefits and properties of non fossil sources
Whilst <100yrs biomass can be converted to fulfil all the roles currently provided by fossil
resources – there is nowhere near enough – so should be applied to highest and best uses –
bioenergy as a by-product.
Biomass comes in 5 Distinct Types
NB: Integration and collaboration across all the biomass sources necessary to achieve cost
effectiveness of final products.
A “scrap yard” for
waste
or
surplus
biomass
A receiver of last resort
A “rail head silo” for specifically grown biomass
A first point of receival
The first point of assessment, value adding and/or
pretreatment for whatever materials is
presented
.
What is a BioHub?
The Main Features of a BioHub
Making finished/tailored products from the full range of
available materials to ensure customer satisfaction:
•
Fertilizers
•
Metallurgical charcoals
•
Bioenergy
•
Supply to high capital processors up the supply chain
Servicing local communities – as part of an integrated network
•
Some too much supply – not enough local markets
•
Some too much product demand – no biomass supply
•
Very few “Goldilocks” opportunities – hence network and
collaboration

Lessons learned for biomass fraction:
–
Paper/cardboard
–
Glass
–
Metals
Two stage process:
–
Waste sector – Fee-for-Service – collect and pretreat
–
Product manufacturing
•
Consumer facing
•
Based originally on virgin supplies
•
Lives and dies on product quality
Success requires recovering resources from urban waste streams such that
they can beneficially supplement/replace virgin resources in established
product manufacturing.
Making “Real” Products from Waste
(
Creating the market pull for recovered resources back into the
productive economy)
What an Integrated “Streaming/Cascading” System
Could Look Like for New England
Projected Benefits for Councils
–
> 90% diversion
–
Cap on waste management charges immediately:
Then CPI certainty
Then downward pressure on costs and charges
–
No need to take process and market risk
–
Opportunity to “invest” in profitable resource recovery
operations
–
Encourage and facilitate growth and employment
Ultimately financed from the recovered value from
the materials under management
Only Collaboration Can Achieve these Results
–
No single industry sector can achieve optimum results on
their own
–
No council can achieve optimum results on their own
–
It requires:
Regional collaboration
Multi council based strategies
Multi product flexibility
Technology as servants not masters
Governments (x3) to support initial scoping, planning
and feasibility studies
Greatly Simplified MSW/AWT
Green/Garden Waste Management
for Best Quality and Value
Advancements in biomass utilization through BioHubs offer a sustainable solution to address global agendas like climate change and resource depletion. Biomass serves as a crucial alternative to fossil fuels, providing a renewable source for essential carbon-based molecules. Various biomass sources, such as forestry residues and urban waste streams, offer diverse opportunities for creating valuable biobased products. The development of specialized BioHubs can enable efficient utilization of surplus biomass, benefitting both the environment and the economy.
