How To Integrate Anaerobic Digestion Into Your Business’s Sustainability Strategy

Published Jan 02, 2025

Are your current sustainability solutions not helping you reach your waste management goals? If you’re ready to take a more impactful approach, anaerobic digestion (AD) could be the right choice.

AD is a naturally occurring process that breaks down organic waste without oxygen, producing biogas and digestate. It's a win-win: You reduce your carbon footprint and create new revenue streams for your business.

But how do you harness the power of AD for your business? In this guide, we’ll outline the exact steps.

What Is Anaerobic Digestion?

Anaerobic digestion (AD) is a natural process. It occurs when microorganisms break down organic matter in the absence of oxygen.

First, food scraps, manure, and other organic waste are fed into the digester. Then, microorganisms feed on the waste, producing biogas and digestate.

Biogas is a blend of methane and carbon dioxide that can be cleaned and used as a renewable fuel. This byproduct can be:

  • Converted into electricity through combustion engines or turbines.
  • Upgraded into biomethane – a renewable natural gas substitute for conventional natural gas.
  • Used as a transportation fuel for vehicles or a feedstock for producing other fuels.

Meanwhile, digestate is the solid or liquid residue remaining after biogas production. It’s rich in nutrients such as nitrogen, phosphorus, and potassium. It can be used as a fertilizer to improve soil health and avoid the need for synthetic fertilizers.

The Importance of Sustainability Strategies for Your Business

Sustainability is no longer an optional practice for companies. Consumers, investors, and regulators are demanding more eco-friendly practices from businesses. Besides being good for the environment, sustainability also helps you protect your bottom line.

Here are some of the many ways sustainability can serve your business.

  • Reduced Costs: Sustainable practices can lead to major cost savings. Think energy efficiency, waste reduction, and water conservation.
  • Improved Brand Image: Consumers are turning to brands that align with their environmental values. A strong reputation for sustainability will boost your brand's public appeal.
  • Customer Loyalty: Customers who feel good about the companies they support are more likely to remain loyal. In fact, 44% of Americans say they wouldn’t buy from a company that isn’t eco-friendly.
  • Compliance With Local Regulations: Environmental regulations are becoming stricter. Sustainable operations can help you stay ahead of the curve and avoid costly penalties.

Integrating AD into your business will allow you to reach your long-term sustainability goals. By turning waste into valuable resources, AD helps businesses in several ways.

  • Offsetting your company’s carbon footprint and contributing to a cleaner planet.
  • Creating new revenue streams by selling biogas or digestate.
  • Mitigating risks surrounding climate change and environmental regulations.
  • Showing your commitment to sustainability to customers, investors, and the community.

Benefits of AD for Businesses

AD creates is a mutually beneficial solution for you and your customers. Businesses can cut costs and contribute to a greener earth.

Reducing Waste Disposal Costs

One of the most immediate benefits of AD is reducing waste disposal costs. Landfills are expensive to operate, and the fees associated with dumping waste can add up quickly. AD allows businesses to reduce the amount of waste they send to landfills, creating major cost savings.

Generating Renewable Energy (Biogas)

AD is a natural way to generate renewable energy. The biogas produced during AD can serve as fuel in several ways.

  • On-Site Electricity Generation: Biogas can be burned in generators to produce electricity that can power the AD facility and even be sold back to the grid.
  • Heat Generation: Biogas can produce heat for heating buildings, drying crops, or powering industrial processes.
  • Transportation Fuel: Biogas can be refined into biomethane – a transportation fuel used to power vehicles.

Producing Valuable Byproducts (Digestate)

In addition to biogas, AD also produces a valuable byproduct called digestate. Digestate is a nutrient-rich liquid that can be used as a natural fertilizer for agriculture. It can be applied to crops to improve soil health, avoid synthetic fertilizers, and maximize crop yield.

Steps to Integrate AD Into Your Business

If you’re considering using AD to make your operations more sustainable, here are the steps to implement it.

Step 1: Assess Waste Streams

The first step in integrating AD into your business is to assess your waste streams. Identify the types of organic waste generated in your operations, such as food scraps, manure, or agricultural residues. Also, determine how much waste you generate daily, weekly, monthly, and yearly.

Step 2: Select AD Technology

Once you've identified your waste streams, you can explore AD technology options. The best option for your business will depend on the volume of waste you generate, your available space, and your budget. There are two main types:

  • On-Site AD Systems: These systems are installed directly on your property, and your waste is processed on-site.
  • Off-Site AD Facilities: These facilities are installed off-site and process waste from multiple businesses.

Step 3: Collaborate With Experts

Integrating AD into your business is a complex process. It’s a wise choice to work with experts who can help you design and implement a system that meets your needs. AD consultants can guide you on everything from technology selection to regulatory compliance.

Step 4: Regulatory Compliance

Before investing in AD, you should research the local regulations and incentives related to AD and renewable energy. Many governments offer specific incentives to encourage businesses to adopt sustainable practices.

For example, in the United States, the Federal Investment Tax Credit (ITC) offers a tax break for companies that invest in renewable energy projects like AD systems.

Measuring Impact

Once you've implemented AD, it's time to track its impact to make sure it's meeting your goals. Here are some key metrics to focus on:

  • Waste Reduction: The quantity of waste diverted from landfills and the resulting cost savings.
  • Energy Production: The amount of biogas produced and the electricity or heat generated.
  • Cost Savings: The cost reductions due to reduced waste disposal, energy generation, and fertilizer production.
  • Environmental Impact: Your carbon footprint reduction and contributions to renewable energy goals.

Conclusion

Anaerobic digestion is an effective waste management system that can set your business up for a greener future. It’ll help you reduce your environmental impact, generate clean energy, and boost your bottom line.
