Session 8: Biogas as a Business

Session 8: Biogas as a Business#

Learning Objectives#

By the end of this session, you will be able to:

Identify the different ways biogas and bio-slurry can generate income.
Understand the basics of costing and pricing a biogas installation service.
Recognise the wider community impact a single trained technician can have.

Testimony: Biogas as a Career#

Sanile shares her experience as a biogas technician and course participant.

Case Study: Benefits of Biogas — Reduced Costs#

Mr Musugu on the financial benefits of biogas: reduced wood, reduced charcoal, and cash savings.

The Business Opportunity#

Biogas as a business — closing the loop, value at every stage, business basics, and cost-generating vs income-generating view — Fig. 32 Biogas creates value at every stage of the cycle — from fuel savings to bio-slurry sales — and shifts the household from a cost-generating to an income-generating model.#

Biogas creates income in three main ways:

1. Cost Savings (for the digester owner)#

Saving	Typical impact
Cooking fuel (firewood / charcoal / LPG)	Eliminated or greatly reduced
Chemical fertiliser	Replaced by bio-slurry
Labour (collecting firewood)	Saved — often hours per day, especially for women
Health costs	Reduced respiratory illness from cooking smoke

2. Productive Use Income (covered in Session 6)#

Brooding services
Fodder chopping
Food drying and processing
Lighting for evening businesses

3. Building and Maintaining Digesters as a Service#

Trained technicians can offer:

Service	Revenue model
Digester construction	One-off fee per installation
Annual maintenance checks	Annual service contract
Pipe repairs and valve replacement	Call-out fee
Training local farmers	Workshop fee or donor-funded

Real Costs and Savings: Example from the Field#

Case: A Typical 5-Cow Household Digester#

Item	Before biogas	After biogas
Firewood cost (per month)	$15–25	~$0
Fertiliser cost (per season)	$40–60	~$0–20 (supplemented by bio-slurry)
Time collecting firewood	1–2 hours/day	0
Cooking smoke exposure	Daily	Eliminated

Annual savings: approximately $200–350 USD — often comparable to the installation cost within the first year.

The Community Multiplier Effect#

One trained biogas technician in a community can:

Install 10–20 digesters per year
Train other community members in operation and maintenance
Build a reputation that generates referrals
Develop an ongoing maintenance income stream

The broader effects:

Reduced deforestation (fewer trees cut for firewood)
Improved soil health (bio-slurry applied across multiple farms)
Reduced indoor air pollution across the community

Testimony: Benefits, Time, and Wellbeing#

Mrs Linguina on the personal impact of biogas: time saved, soot eliminated, and quality of life.

Testimony: Friends with Nature — Sandy#

Building a Biogas Business#

Biogas offers multiple services to people: clean, modern and free energy, effective waste management, and quality organic fertiliser. To bring these benefits to more people, we cannot rely on charitable giving alone. Business is the most effective means to expand the benefits of biogas in a financially sustainable way.

To start a successful biogas business you need three things:

A product or service — a valuable offering that meets customer needs.
A market — a group of people willing to pay for it.
A revenue model — a sustainable way to generate income and keep the business running.

The business can only work if there are enough paying customers to provide income. Keep the customer at the forefront of your mind and build your business around their unmet needs.

Types of Biogas Business#

There are three main models:

Model	Description
Product-based	Construct and install biogas systems for households, schools, or institutions. May also include service and maintenance contracts.
Gas service-based	Build a large plant and supply biogas to nearby customers — works well with consistent waste supply (zero-grazed animals, community toilets).
Productive-use based	Use biogas to produce another product or service — roasting coffee, cooking food, running a small manufacturing process.

Before You Start#

Consideration	Questions to ask
Knowledge and expertise	Do you have the technical skills to build and maintain systems?
Market demand	Who are your potential customers? What are their needs?
Regulatory requirements	Are there local safety or legal regulations that apply?
Financial planning	How will you fund the business and ensure profitability?

Finding a Founding Team#

Starting a business is easier and more successful with a team. A strong founding team should cover:

Technical skills — biogas construction and maintenance expertise
Financial management — budgeting, pricing, and accounting
Marketing and sales — ability to attract and retain customers

Creating a Market#

Building a market requires understanding your customers. Key steps:

Market research — Identify who benefits from biogas and what challenges they face.
Demonstration projects — Show potential customers how biogas works and the benefits it provides.
Customer education — Provide training and support so people feel confident using biogas.

Business Operations and Procurement#

Efficient operations are essential. Consider:

Supply chain management — Ensure a steady supply of construction materials.
Equipment sourcing — Find reliable suppliers for system components.
Service delivery — Set up processes for installation, maintenance, and troubleshooting.

Seed Funding#

Every business needs initial capital. Possible sources:

Source	Notes
Personal savings	Investing your own money reduces dependence on others
Grants and competitions	Organisations that support renewable energy initiatives
Loans and microfinance	Banks or microfinance institutions
Partnerships	NGOs, government agencies, or investors who share your vision

Marketing and Sales#

Effective strategies for attracting customers:

Word-of-mouth — Encourage satisfied customers to share their experiences.
Community engagement — Host workshops or demonstrations to raise awareness.
Online presence — Social media and websites reach a broader audience.
Partnerships — Work with local businesses or organisations to promote biogas.

The Business Model Shift: From Cost-Saving to Income-Generating#

Traditionally, biogas has been positioned as a cost-saving technology:

“Save money on LPG or charcoal” · “Reduce your fuel expenses”

This positioning has limitations. If a family already spends little on fuel, the savings may not justify the digester investment (UGX 2.5 million for a typical 9 m³ system — a 12-year payback).

Productive use changes this equation fundamentally. It transforms biogas from a cost-saving technology into an income-generating asset:

Framing	Annual value	Payback period
Cost saving (“save on cooking fuel”)	UGX 200,000/year	12 years
Income-generating (“brooding services + briquette sales”)	UGX 3,200,000/year	0.3 years

This reframing is critical for:

Accelerating biogas adoption among farmers who see it as a business investment, not just a household expense.
Justifying larger digesters that can support both household use AND productive applications.
Creating sustainable businesses around biogas services (brooding-as-a-service, food processing, etc.).

Note

Building a biogas business requires commitment, a strong team, and careful planning. A customer-driven approach — always asking “what does this person need?” — is the single most important habit for long-term success.
