Food waste

An increasing focus for biogas plants are treatment of food waste for biological treatment. 
 
Alternative treatment solutions such as landfill or incineration are not very feasible solutions anymore. Waste is being diverted from landfills all over the world, due to the environmental impact and the long-term cost for handling landfills. For incineration plants wet biomasses such as food waste reduce the burn value and are better handled by biogas plants.
 
Treatment of source separated food waste by anaerobic treatment in a biogas plant is the more sensible solution from an environmental and economical point of view.
 

Sources of food waste

Food is being wasted at very large volumes today.
 
FAO United Nations estimate that globally one third of the food produced is not consumed, but ends up as food waste. Every year there are 1.3 billion tons of food waste. Read more here: http://www.fao.org/food-loss-and-food-waste/en/
 
There is food waste in every stage from farm to table.
 
Our plants receive biomasses sush as household waste, supermarket waste, waste from catering, restaurants, vegetable markets and other food waste. Read more about Xergi biogas plants in references.
 

High energy content

Source separated household waste is a high energy biomass for a biogas plant, and considered a very good source of biomass by Xergi. This makes will enable us to design a very compact and highly efficient biogas plant with a large production of renewable green energy to the electricity grid or to be used as biomethane.
 

Circular economy

Processing food waste in a biogas plant is the perfect example of a circular economy.
 
Food is produced by the agricultural industry. This is used by consumers, but some of it ends up as food waste, an Xergi biogas plant will process the food waste and produce digestate, which is an excellent fertilizer. The fertilizer will be returned to the agricultural industry for production of new food. Perfect!
 
This is a way of recycling food waste and the nutrients back to the soil. In addition, don’t forget in the recycling this organic waste, we produce a renewable energy.

Xergi biogas systems help to achieve local targets for the environment, climate and economy

Xergi biogas plants primarily treat local resources like animal manure, waste and other organic materials, converting them into green energy and sustainable fertiliser products.

In this way we help public authorities to create better and greener ways of using resources from the local community, and similarly, we help to promote local investments and workplaces.

Better utilisation of local resources

Xergi biogas plants help to utilise local resources for production of

• Green electricity
• Green heating in public offices, businesses and private households
• Biogas for use in urban buses, home-care service cars and in the private transport sector
• Biogas for use in industrial production
• Green fertiliser products for local farms and market gardens

Climate targets, environment and economy

Xergi biogas systems solve several problems in one go.

The plants help to achieve several of society's targets for the climate and environment and economy, for example:

• Reductions in the emission of greenhouse gases, from energy production, agriculture and waste disposal
• Better exploitation and recirculation of nutrients
• Less impact from nutrients on the water environment
• Less imported fertiliser
• Promoting local investments and workplaces in the energy sector, logistics and green industry

High quality biogas systems

Xergi has more than 25 years' experience of designing and building high quality biogas systems. We have developed plant designs that ensure great flexibility, high energy output and stable operation.

Getting started

We will be happy to invite you to an introductory meeting to discuss your potential project. Among other things, we can assist with calculating the gas potential in the feedstock you have available. The gas potential is used to calculate the size of the biogas plant. We can then assist with moving the process forward.

Xergi works with biogas projects throughout the entire process: Project development, project design, permits, construction, commissioning and operations.

New opportunities from green energy production

Xergi biogas plants treat organic material, which is converted into green energy and fertiliser.

We help you to set up new sustainable energy production, which can help you to develop your business as an energy supplier.

Xergi biogas plants can utilise the biogas for energy production in a CHP (combined heat and power) plant, but the gas can also be upgraded to natural gas quality and injected into a gas grid.

High energy production and stable operation

Xergi has more than 25 years' experience of designing and building high quality biogas plants. We have developed plant designs that ensure great flexibility, high energy output and stable operation.

Our biogas systems are designed to handle many different types of biomass. Thus it is possible to regulate and optimise gas production and reduce dependency on one particular type of biomass to a minimum.A chance to develop your market position.

With Xergi's biogas systems you can enhance your position on the market by:

• Positioning yourselves on one of the important energy platforms of the future
• Increasing green gas production to replace fossil natural gas
• Reducing dependency on fossil fuel prices
• Obtaining a greater spread of risk through greater diversity in energy production

Strengthen your green profile!

When animal manure, waste and other organic materials are converted into energy, you will be able to strengthen the company's green profile.

You can do that for instance through

• Reduced emission of greenhouse gases
• Recycling waste and residual products
• Increased recirculation of nutrients
• Lower quantities of nutrients discharged to the water environment
