​Ener-t is currently involved in providing economic and ecological waste-to-energy solutions for agriculture– livestock and crop waste.

​

Ener-t is active in the promotion and development of Biogas Projects.

​

The biogas is converted to green electricity or heat for the grid, or used as gas, CNG, LNG for industrial or private use.

 

What is Biogas?

​

Biogas is generated from organic waste by a process known as anaerobic digestion (AD).

 

Specialized bacteria digest the waste, generating methane-rich gas (biogas). This gas is then used in a gas engine to produce renewable electricity and heat.

 

The solids and liquids left after biogas production is known as digestate, and is a nutrient-rich fertilizer beneficial for agriculture, similar or preferred to compost.

Biogas is generated by anaerobic digestion of waste and is used to generate renewable heat and electricity via a gas engine. Therefore, using gas from waste as a form of energy is a great way to combat global warming.

How Does Anaerobic Digestion Work?

Anaerobic digestion is a process through which bacteria break down organic matter—such as animal manure, wastewater biosolids, and food wastes—in the absence of oxygen. Anaerobic digestion for biogas production takes place in a sealed vessel called a reactor, which is designed and constructed in various shapes and sizes specific to the site and feedstock conditions. These reactors contain complex microbial communities that break down (or digest) the waste and produce resultant biogas and digestate (the solid and liquid material end-products of the AD process) which is discharged from the digester.

Multiple organic materials can be combined in one digester, a practice called co-digestion. Co-digested materials include manure; food waste (i.e., processing, distribution and consumer generated materials); energy crops; crop residues; and fats, oils, and greases (FOG) from restaurant grease traps, and many other sources. Co-digestion can increase biogas production from low-yielding or difficult-to-digest organic waste.

​

Several biogas systems with combined heat and power (CHP) generation are currently under development/construction by Ener-t.

​

Why Anaerobic Digestion?

​

•Reaction takes place in a fully closed system, sealed digester vessel, with no gases or odors escaping to the environment. Closed system also prevents contamination of the digestate by, e.g., vermin or pathogens

​

•All methane produced is captured and used to generate carbon-neutral electricity (and revenue!), instead of being released as a greenhouse gas (and costing money!)

​

•Estimated savings in cost of greenhouse gases is USD 1.2 million per year compared to aerobic compost open/sealed compost plant

​

•All CO2 emissions are generated at a point source, i.e., the CHP generator stack, and are catalyzed and cleaned per emissions standards prior to release

​

•Time- and temperature-controlled process engineered to provide predictable output and denature pathogens present in feedstock

​

•Heat from the CHP can be utilized by the process to speed up processing times and sanitize the output products

•Pathogenic problem of agricultural crop is solved in our AD process

​

•Moisture content of output can be mechanically controlled. Water is not lost in the process and can be recycled in the digester. Process is engineered to produce little to no water effluent, and no water shall be spread on fields. What little effluent may be generated shall be treated to meet standards for acceptance by the local treatment facility.

​

•Unlike with compost, process is sealed and no odors are released to the environment

​

•End product, anaerobic digestate, can be used as agricultural fertilizer with no further treatment
