Anaerobic Digestion / Biogas

OMNI Heat & Power are dedicated to the highest standards of equipment and installation.

As manufacturers of waste to energy plants and heat and power solutions with our own in-house experts of engineers, designers, and consultants, we have a comprehensive understanding of customers’ requirements for reducing operating costs, creating value from waste, reducing costs of waste and operational convenience from waste to energy plants and heat and power solutions.

Benefits of Anaerobic Digestion / Biogas

  1. Waste into Energy – anaerobic digestion is a method of turning your waste products into clean, green and usable energy. Any business in the agricultural field, in sewage, and even in food processing, produces waste that can become energy. It makes sense, and we can help you do it!
  1. Green and Clean – all energy created by anaerobic digestion process is as ecologically friendly as it gets. By recycling your waste by-products in this way you are using everything as efficiently as possible, and doing your bit to help the country meet its renewable energy aims.
  1. Cost-Effective – the cost savings gained by using waste products to create the energy you use will be notable very quickly. Any anaerobic digestion produced energy is a saving, and it will help you cut back on your energy costs immediately you begin the process.
  1. Not Just Heat – if you take things a step further you can use the anaerobic digestion system to remove the majority of carbon dioxide from the biogas – this being the product of the process that is used to provide electricity and heat. This results in biomethane, which is suitable for powering vehicles and other uses, and the by-product is also suitable as organic fertilizer.
  1. Reduce Landfill – most of the waste you currently send to landfill sites can be used for anaerobic digestion to produce biogas. So, rather than leaving your waste materials to rot and emit methane and carbon dioxide, you are going even further in advancing your green credentials by recycling your waste by-products into energy.

The above are just some of the benefits of using our anaerobic digestion systems to convert your waste products into energy, and there are many more.

Why choose OMNI Heat & Power?

Being an engineering and design company, we have the knowledge and expertise to design a complete Anaerobic Digestion process tailored for your specific needs. 

From the point at which the feedstock enters our system, we have complete control of the process design.

Typical design variations include tank sizes, pumping and mixing requirements and feedstock pre-processing to name a few.

We design the processes required to get the most from your waste stream, complete with the sensors and automation required to keep it running smoothly with minimal intervention.

Anaerobic Digestion plants have no one size fits all solution.

With this in mind; OMNI Heat & Power are the perfect partners for any business looking to process a waste stream into useful energy.

Biogas from OMNI Heat & Power

OMNI Heat & Power is a Waste to Energy engineering and design company. 

Founded in 2015, the company has extensive experience in the design and manufacture of different Anaerobic Digestion (AD) design processes and feedstocks. 

Having built over 10 waste to energy plants from 30kW to 1.2mW we have an unrivalled experience in this sector.

On Farm Anaerobic Digestion

Small Scale

Designed to compliment an existing dairy business. With solutions from 40kW – 500kW we can provide a solution to any farm with a herd from 150 cows or larger.

Automatic

The operation of the biogas plant is fully automated, allowing you to carry on farming. Using Siemens automation technology with remote access and control.

Popular

OMNI Heat & Power have built over 10 new biogas plants since 2016. Over 1000+ new on farm anaerobic digestion plants are expected to be built across Europe by 2025.

Calculate what size biogas plant you could have

You can never know exactly what size anaerobic digestion biogas plant is suitable for you without taking samples of your potential feedstocks, and analysing the potential volumes available.

However, below is a guide using industry standards for estimating what size plant is suitable for you. 

First how much biogas can you produce per tonne of potential feedstock. 

To find this out a sample is taken and sent off to a lab for a BMP test, (bio methane potential test). 

This test tells us how much biogas or methane is available per tonne of sample feedstock.

This is the important part, because it tells us exactly how much fuel you have available per tonne of material.It is important not to confuse biogas and methane (CH4) as biogas typically only contains around 60% methane (CH4).

The methane content is what we are more interested in as this is what we can use as fuel in a combined heat and power engine. 

Second step is to analyse how much feedstock you have available to use in an anaerobic digestion plant. 

Some farms may have information on the amount of slurry produced a year.

Alternatively we can make an estimate from the milk yield of the cows, using standard industry figures.

Final and third step is to know the efficiency of the proposed combined heat and power engine. 

OMNI Heat & Power use engines from Cummins, alternators from Stamford, Exhaust Heat Exchanger from EJBowman and Engine Controllers from Deep Sea. 

All widely recognized and available components which together form a Combined Heat & Power Engine (CHP).

Electrical efficiency for any combined heat and power engine is usually around 35%, the exact efficiency can vary depending on load factor and also engine size.

Now we have all these three variables, we can use this to calculate what size plant is suitable for your farm.
