Bioeconomy
Introducing a Circular Carbon Economy at Regional Level
Decisions about biomass are already part of regional infrastructure — from agricultural residues and green waste to forestry by-products and organic municipal waste. These materials are central to the bioeconomy, yet the way they are used often determines whether carbon is retained in the region or released quickly back into the atmosphere.
The bioeconomy broadly aims to replace fossil resources with biological ones. However, not all bio-based pathways deliver the same climate benefits. Many still lead to rapid carbon release, for example through short-lived products or energy use. This learning module therefore approaches the bioeconomy through a more specific lens: the Circular Carbon Economy.
A Circular Carbon Economy focuses explicitly on carbon management. It asks not only which biological resources are used, but how carbon flows through regional value chains — and how long it remains in productive use. The goal is to retain, stabilise and reuse carbon as part of coordinated regional systems, rather than allowing it to escape quickly as CO₂.
This perspective represents a clear shift:
- from linear biomass use to circular carbon value chains,
- from carbon as a problem to carbon as a measurable and manageable resource, and
- from isolated bio-based projects to integrated regional strategies.
For regional stakeholders — including agriculture, construction, horticulture, waste management and municipalities — this approach creates concrete opportunities. Residual biomass can be converted into long-lasting carbon-based products, such as biochar applications in construction materials, soils, landscaping or technical systems. In doing so, regions can reduce emissions, create durable carbon sinks and strengthen local economies at the same time.
Introducing a Circular Carbon Economy requires collaboration across sectors and shared tools for decision-making. Stakeholders need a common basis to assess carbon impacts, compare options and develop solutions that make sense under real regional conditions.
Building on the previous modules, this learning unit guides you step by step from understanding regional carbon potential to developing a concrete bioeconomy project — turning climate objectives into practical, region-specific action.
Biomass and Carbon Potential Analysis
Understanding the Carbon Sink Potential of Your Region
Before project ideas can be developed, technologies selected or partnerships formed, one fundamental question must be answered:
How much carbon can be stabilised and stored within the region through the use of biochar?
This potential is defined not only by the upstream availability of residual biomass, but also by the downstream capacity of the region to use biochar in meaningful and long-lasting applications. A Circular Carbon Economy project can therefore start from two complementary perspectives: upstream and downstream.
From an upstream perspective, residual biomass represents a source of carbon that is often underused or lost through disposal or combustion. Understanding which biomass streams exist, in what quantities and under what conditions, is essential for assessing how much carbon could realistically be captured and stabilised as biochar.
From a downstream perspective, biochar only creates impact if it can be absorbed by regional applications. Construction, horticulture, agriculture, landscaping or technical uses each have different requirements and volumes. Analysing how much biochar could realistically be used in the short, medium and long term is therefore just as important as knowing how much biomass is available.
Together, upstream biomass potential and downstream application potential determine how much carbon can be retained, circulated and put to productive use within a region. Focusing on only one side risks creating projects that either lack feedstock or lack viable applications.
A systematic analysis helps to clarify:
- which residual biomass sources exist upstream,
- how much biomass could be recovered and how much biochar produced,
- which downstream biochar applications are feasible, and
- how upstream and downstream potentials can be aligned.
In the following task, this analysis will be approached from one of these two entry points, depending on your role or perspective. Combined, they form the foundation for carbon assessment with CCMS, stakeholder mapping and realistic project development.
By starting with both upstream and downstream perspectives, a balanced and region-specific basis is created for Circular Carbon Economy projects that can move from idea to implementation.
Task 1: Analyse Carbon Potential in Your Region
Circular Carbon Economy projects can be approached from different starting points. Choose the option that best fits your role or perspective.
a) Biomass-Driven Perspective (for stakeholders close to biomass supply, recovery or processing)
Analyse the residual biomass flows in your region to identify biomass streams that are underused or lead to rapid carbon release. Use available data and local knowledge to understand their origin, quantities, seasonality and current use.
Document the results in the Biomass Factsheet, including:
- Type of residual biomass
- Approximate quantities and seasonality
- Origin and current use
- Key constraints
b) Application-Driven Perspective (for stakeholders close to construction, horticulture or other end uses)
Starting from a specific product, process or application, estimate how much biochar could realistically be used:
- in the short term (pilot or initial use),
- in the medium term (scaling within current operations),
- in the long term (full potential or broader adoption).
Document these estimates, along with any assumptions, requirements or constraints.
Estimates are sufficient. The gathered data provides the basis for carbon assessment with CCMS and further project development.
Generate Biochar Project Ideas from Different Entry Points
Choose the task that best fits your role or perspective — or complete both if relevant.
a) Biomass-Driven Perspective (for stakeholders closer to biomass supply, recovery or processing)
Based on the biomass analysis, identify residual biomass streams in your region that are currently underused or could be used more effectively for biochar production.
Brainstorm and briefly describe 2 biochar-related project ideas, focusing on how these biomass streams could be converted into biochar and used in local or regional applications.
b) Application-Driven Perspective (for stakeholders closer to product development, construction, horticulture or end use)
Starting from your current products, services or applications, identify where biochar could be integrated or could replace less sustainable materials or practices.
Brainstorm and briefly describe 2 biochar-related project ideas, focusing on potential uses, benefits and performance requirements from a user perspective.
The aim is to explore different entry points into biochar value chains and to make visible where supply and demand perspectives can connect in the next steps of the module.
Introducing the Circular Carbon Management System (CCMS)
The carbon potential analysis has provided a clearer understanding of the regional situation — both upstream, in terms of available biomass, and downstream, in terms of possible biochar applications. The next step is to move from collected data to structured project development.
While the Circular Carbon Economy offers an overarching framework, regions need a practical tool to work systematically with carbon when designing projects, comparing options and making decisions across sectors. Measuring emissions alone is not sufficient. What is needed is a way to make carbon flows visible, comparable and actionable at regional level.
The Circular Carbon Management System (CCMS) was developed to meet this need. It is grounded in the Carbon Handprint philosophy, which shifts the focus from avoiding emissions to actively creating positive impact — by keeping carbon in use rather than allowing it to escape immediately as CO₂.
CCMS treats carbon as a measurable unit of value, comparable to the role money plays in a local economy. Just as a Euro can generate greater benefit when it circulates within a region, carbon can deliver higher climate, economic and social value when it remains within regional value chains. CCMS helps analyse how different choices influence this circulation.
In many conventional biomass pathways, carbon leaves the system quickly through combustion, decomposition or short-lived uses. CCMS systematically evaluates alternative pathways, making it transparent where carbon is lost, where it is retained, and how it can be stabilised and multiplied through circular use.
CCMS was specifically designed to accompany the biochar value chain. Biochar provides a concrete and robust way to work with carbon flows, because it converts carbon captured by plants via photosynthesis into a stable, solid form that can be integrated into long-lasting products and applications. CCMS quantifies how much carbon is retained through biochar production, where it is stored along the value chain, and how upstream biomass choices and downstream applications interact at regional level.
In this learning unit, CCMS is applied as a hands-on working tool. Using real or realistic data from your region, the previously gathered information is analysed step by step to:
- map biomass sources and value chains,
- analyse carbon flows and losses,
- compare alternative utilisation pathways, and
- identify opportunities to improve carbon retention and local value creation.
By expressing impacts in a common unit — carbon — CCMS creates a shared analytical basis for dialogue between agriculture, construction, horticulture, municipalities and other sectors. It supports informed decision-making and helps translate climate goals into concrete, region-specific project concepts.
In this way, CCMS enables stakeholders not only to assess what happens, but to actively shape outcomes — leaving a clear and intentional Carbon Handprint that others along the value chain can recognise and build upon.
Apply the Carbon Management Tool to Your Bioeconomy Project
In this task, you will apply the Circular Carbon Management System (CCMS) to your bioeconomy project idea.
Using the results from your biomass and/or carbon potential analysis, enter the relevant information into the tool to map and assess carbon flows along your value chain.
Focus on:
- Defining the scope of your project
- Identifying where carbon is retained or lost
- Comparing different biomass utilisation options
Estimates and assumptions are sufficient. The aim is to use CCMS to understand the carbon potential of your project and create a solid basis for the next steps.
Getting the Right People on Board
Regional bioeconomy projects are not successful solely on the basis of technology and sound calculations. They succeed because the right people are involved at the right time.
Whether a project focuses on biochar, residual biomass or circular carbon value chains, its success depends on cooperation across many sectors. Biomass availability, processing, product development, certification, marketing and final use are usually spread across different organisations, professions and interests. If even one key group is missing or involved too late, promising projects can stall or fail.
Stakeholder analysis is therefore one of the most important early steps in any regional bioeconomy initiative. It helps to answer practical questions such as:
- Who controls or provides the biomass?
- Who is responsible for collection, recovery and logistics?
- Who operates or could operate conversion technologies such as pyrolysis?
- Who develops, certifies, sells or uses the final products?
- Who provides expertise, research, advice or quality assurance?
- Who needs to approve, support or regulate the process?
In a Circular Carbon Economy, stakeholders are connected along a value chain, not working in isolation. Understanding these connections makes it easier to identify cooperation opportunities, anticipate challenges and build trust between partners.
In the following learning unit, you will apply this approach to your own regional scenario. You will be guided to map relevant stakeholders along the value chain, including:
- Biomass suppliers
- Recovery and logistics actors
- Conversion and processing (e.g. pyrolysis)
- Retailers and market actors
- Auditors and laboratories
- Advisors and service providers
- Research and development organisations
- Users of biochar-based products
- Public authorities and municipalities (where relevant)
By filling in the stakeholder scheme with real names of people, businesses and organisations, you will begin to turn an abstract project idea into a real, workable regional network.
This step lays the foundation for everything that follows — from pilot implementation to scaling up and achieving long-term impact.
Identify and map relevant stakeholders
Identify the key stakeholders relevant to the bioeconomy project and enter them into the stakeholder diagram provided.
Think about all organisations, businesses and institutions that are relevant along your project’s value chain — from biomass supply to final use.
Enter the names of real people, companies or organisations where possible, or the type of actor if specific names are not yet known.
The goal is to create a realistic overview of who needs to be involved to make your project work, and to identify where cooperation or new connections may be required.
