What Is Biogas, Who Should Use It, and How Is su-re.co Using It in Indonesia?
What if kitchen scraps and livestock manure could help provide cooking energy while supporting agricultural production?
For many rural communities, organic waste is a daily challenge. However, with suitable technology, it can also become a valuable resource.
One solution is biogas, a renewable fuel produced through the natural breakdown of organic materials.
In Indonesia, biogas offers opportunities for households, farmers, and communities seeking practical waste management and decentralized energy solutions.
But how does biogas work, who can benefit from it, and where is it most suitable?
This article explains the fundamentals of biogas and how su-re.co connects biogas technology with circular agriculture and community resilience.
What Is Biogas?
Biogas is a combustible gas produced when microorganisms break down organic matter in an environment without oxygen.
This biological process is called anaerobic digestion.
Biogas typically contains methane and carbon dioxide, along with smaller amounts of other gases.
Methane is the component that enables biogas to be used as fuel.
Depending on the system and its specifications, biogas can support applications such as:
Household cooking
Heating
Electricity generation
Certain agricultural and commercial energy needs
For small-scale biogas systems in Indonesia, cooking fuel is often one of the most practical applications.
Unlike conventional fossil fuels, biogas is generated from renewable organic materials.
However, its environmental performance depends on feedstock management, system operation, and preventing methane leakage.
How Does Biogas Work?
Biogas is generally produced inside a sealed system known as a biogas digester or biodigester.
The process can be summarized in four steps.
Organic waste collection: Suitable materials, such as animal manure or food waste, are collected.
Anaerobic digestion: Microorganisms break down the materials without oxygen.
Biogas production: Methane-containing gas is generated and captured.
Resource recovery: Remaining digestate or bioslurry can be managed for agricultural use.
This process creates two potential benefits from the same organic material: renewable energy and nutrient recovery.

Who Should Consider Using Biogas?
Biogas is particularly relevant to people and organizations with a consistent supply of suitable biodegradable materials.
1. Livestock Farmers
Farms producing regular quantities of manure may be suitable for small-scale biogas.
The gas can potentially support household energy needs, while bioslurry provides an opportunity to recover nutrients for crops.
2. Rural Households
Households with available organic feedstock, suitable space, and reliable maintenance capacity may benefit from a decentralized cooking energy system.
Biogas can potentially reduce dependence on purchased cooking fuel or collected firewood.
3. Agricultural Businesses
Certain agricultural operations generate organic byproducts that may be suitable for digestion.
Biogas can become part of a broader resource management strategy when sufficient feedstock and appropriate technical support are available.
4. Hospitality and Food Businesses
Restaurants, hotels, and food-processing businesses may consider biogas where organic waste is consistently available.
However, feasibility depends on waste composition, operational scale, available space, and management requirements.
Where Is Biogas Suitable in Indonesia?
Indonesia's agricultural and livestock sectors provide opportunities for biogas development.
Potential applications include rural farming areas, livestock-producing communities, and locations where organic waste is regularly generated.
For example, su-re.co has worked with farming communities in Bali and Bajawa, Flores, where portable biogas systems have been introduced.
However, biogas is not automatically suitable for every household or location.
Before adopting a biodigester, several conditions should be assessed:
Availability of consistent organic feedstock
Access to sufficient water
Appropriate installation space
Local temperature and operating conditions
Ability to maintain the system
Demand for cooking gas and fertilizer
A location with insufficient feedstock or limited maintenance capacity may require a different waste management solution.
What Are the Benefits of Biogas?
When properly designed and operated, biogas systems can provide several environmental and social benefits.
1. Renewable cooking energy
Captured biogas can replace part of a household's conventional cooking fuel requirements.
2. Organic waste management
Suitable biodegradable waste can be processed in a controlled system rather than left unmanaged.
3. Bioslurry fertilizer
Digestion produces nutrient-containing material that can support agriculture when appropriately treated and applied.
4. Potential household savings
Where biogas replaces purchased fuel or fertilizer, it may reduce certain recurring expenses.
5. Circular resource use
Biogas connects waste recovery with energy generation and agricultural production.
These outcomes depend on consistent operation and local conditions rather than installation alone.
How su-re.co Uses Biogas in Indonesia
At su-re.co, biogas is not treated simply as a waste-to-energy technology.
Instead, it forms part of a wider system connecting renewable energy, agricultural practices, and farmer resilience.
Through its Do-Tank programs, su-re.co develops portable biodigesters using locally sourced components.
Its lightweight, foldable design is intended to make installation and deployment more practical, including in certain remote communities.
The system converts suitable organic waste into cooking gas and bioslurry fertilizer.
But the approach extends beyond the equipment itself.
su-re.co also connects biogas activities with climate education, farmer partnerships, and sustainable agricultural practices.
This integration helps communities consider waste, energy, soil health, and livelihoods as connected issues.
When Should You Consider Installing a Biogas Digester?
A biogas digester may be worth exploring when organic waste is consistently available and there is a clear need for cooking energy or nutrient recovery.
Before proceeding, assess the feedstock, site conditions, expected energy demand, maintenance requirements, and economic feasibility.
Working with an experienced provider can help determine whether biogas is appropriate.
From Organic Waste to Community Resilience
Biogas demonstrates how everyday organic materials can support more circular resource management.
Its potential value goes beyond producing renewable fuel. When integrated with agriculture, biogas can connect waste recovery, soil nutrients, local energy needs, and community livelihoods.
That is the broader approach su-re.co is developing through its farmer-centered initiatives in Indonesia.
