The Benefits of Anaerobic Digestion Solutions

Published Apr 11, 2024

As our global community faces the pressing challenges of climate change, resource depletion, and environmental degradation, there's increasing focus on renewable energy sources and sustainable waste management practices. One natural biological process is anaerobic digestion, which breaks down organic materials without oxygen. The end result is biogas and digestate — two valuable products that can be used for renewable energy and fertilization. With an anaerobic digestion solution, you can decompose organic matter, such as food waste, agricultural residues, and wastewater sludge without having to send it to the landfill, where it contributes to greenhouse emissions.

The process begins with collecting and preparing organic feedstock, which is your waste. It’s then fed into a digester, where the material is crushed and macerated to make it easier for the microbes to do their job. The decomposition process produces methane that gets captured and converted to Biogas. The biogas will be used as a renewable energy source, while the remaining material — called digestate — becomes a nutrient-rich liquid fertilizer.

This sustainable waste management process reduces greenhouse gas emissions. Your waste is turned into renewable energy instead of contributing to climate change. Renewable energy provides constant income.

Environmental Benefits

Normally, waste is sent to landfills where it decomposes and releases the greenhouse gas methane into the atmosphere. An anaerobic digestion system keeps methane out of the atmosphere and uses it to produce a renewable energy source. This is a huge environmental win since it also reduces your reliance on fossil fuels.

Biogas is primarily methane and carbon dioxide. Together, these two gasses account for 91% of global emissions. Although methane only makes up 11.5% of emissions, it’s much more effective at trapping heat in the atmosphere. Methane has been responsible for 30% of total warming since the Industrial Revolution.

Through anaerobic digestion solutions, biogas can be purified to natural gas standards. You can use it for electricity, heating, and even as a fuel for vehicles. While biogas isn’t commonly used for vehicles, it can be a viable option if you have a vehicle that’s been modified to run on natural gas. Transforming harmful waste into energy is a sustainable approach to managing organic waste because it’s a closed-loop system. You can benefit the environment and your bottom line.

Through anaerobic digestion, you reduce the amount of waste that has to go to landfills and minimize the harmful environmental issues associated with landfilling, such as leachate — a contaminated liquid that collects at solid waste sites.

Not only does anaerobic digestion keep harmful waste from ending up in a landfill, but it also produces a natural fertilizer that reduces the demand for synthetic fertilizers. This reduces the waste associated with producing fertilizer and improves your soil.

Economic Advantages

Many of the environmental advantages of anaerobic digestion translate into economic advantages as well. You can save money because you won’t need to pay to dispose of waste and you’ll produce free energy from biogas. By processing organic waste on-site, businesses and municipalities can eliminate many costs associated with waste transportation and disposal fees.

Biogas is a renewable energy source that can be converted into electricity, heat, or fuel. In addition to saving money on waste disposal, you’ll save money on utilities. You can use the generated energy for your operations to reduce or eliminate the need for external energy.  If you produce surplus energy, you may be able to sell it back to the grid or to third parties, creating an additional revenue stream. Investing in anaerobic digestion and other sustainable practices may also qualify for government incentives, grants, and tax benefits, which are designed to encourage renewable energy production and sustainable waste management.

Companies that adopt these practices can also strengthen their market position and brand image by appealing to environmentally conscious consumers and stakeholders. According to one study, 78% of consumers state that a sustainable lifestyle is important to them.

Implementation Strategies

To get the most out of an anaerobic digestion solution, start by conducting a thorough waste audit to understand the quantity and composition of the organic waste you generate. This will help determine the appropriate size and capacity of the anaerobic digestion system needed to effectively process the waste.

Once the waste audit is complete, explore different anaerobic digestion technologies to find one that matches your specific needs. Factors such as the available space, the type of organic waste, and desired end-products, such as electricity, heat, or vehicle fuel, factor into selecting the right system. Small-scale systems might be suitable for individual businesses or farms, while larger facilities may require more complex, high-capacity solutions.

We recommend that you consider the financial implications, including potential savings on waste disposal, revenue from biogas production, and any available government incentives or subsidies, when you’re calculating the cost. In addition to the up-front costs, factor in the long-term maintenance and operation of the system to ensure its sustainability and efficiency.
