Jones Engineering Bio Energy Division

Jones Celtic BioEnergy provides a complete solution for the generation of renewable energy from biodegradable sources, such as municipal waste, food waste, agricultural waste and biomass. This is achieved through use of anaerobic digestion combined with composting processes to generate renewable energy, in the form of renewable gas, electricity and heat, according to customer and market demands.

BioEnergy Division Overview

We offer unparalleled delivery of a range of BioEnergy technologies which are modelled and tailored to the specific requirements of our clients. Our range of services includes: –

  • Thermo–Pressure Hydrolysis
  • Dry anaerobic digestion
  • Wet anaerobic digestion
  • In-Vessel composting
  • Biogas upgrading

How we do it!

Thermo-Pressure Hydrolysis

Revolutionary pre-treatment process to convert most biogenic materials into a fully hydrolysed, pumpable fluid with maximum biogas potential.

Dry Anaerobic Digestion

Dry fermentation involves the anaerobic decomposition of “dry” non-pumpable biological material in the absence of oxygen. The process involves the loading of “anaerobic” tunnels with material using loading shovels. The process is particularly suited to bio-waste and mixed waste applications. The system promotes efficient biogas production with very low parasitic energy demands.

Wet Anaerobic Digestion

Wet fermentation involves the anaerobic decomposition of “wet” pumpable biological material in the absence of oxygen. The process involves the loading of “anaerobic” stirred tanks to promote biogas production. These systems are best suited to the digestion of liquid material and silage.

In-Vessel Composting

Composting is the aerobic transformation of biological material in the presence of oxygen and can be engineered in a number of ways. Jones Celtic BioEnergy deliver projects involving Tunnel Composting, Container Composting and Aerated Pile Composting technologies.

Biogas Upgrading

We operate with a number of different upgrading technologies and can tailor our solution to the needs of individual clients and specific waste streams. This system can be adjusted to meet the strict requirements of gas injection to the grid and of compressed biomethane as a vehicular fuel.

A Next Generation Biogas Plant

Thermo-Pressure Hydrolysis (TPH)

In partnership with Aerothermal we are now offering a next generation biogas plant through the utilisation of our patented TPH technology. The TPH technology allows a much wider range of bio-wastes to be utilised in the wet digestion process while generating maximum biogas productivity. For example, cardboard and biodegradable packaging is effectively hydrolysed. This technology will change the face of the biogas industry. The system can also process a much larger range of materials compared with existing thermal hydrolysis processes.

Construction on the Huntstown AD project was split into 4 no. discreet areas:

Reception Building – Material handling and hydrolysis that includes an Odour abatement system, Thermal drier for sludge, Plant Rooms, Transformers X 2 , ESB sub-station,  MV & LV Rooms, MCC Room,  Welfare and Administration facility for Operational staff.

Anaerobic Digestion (AD) Facility – consisting of Screening, Grit Removal and Cooling systems. 2no. Buffer Tanks (circa 1000m3 each), 4no. Primary Anaerobic Digesters (4000m3), 2no.  Secondary Digesters (4000m3), and 3no Pump rooms.

Energy Centre – Gas Storage, Steam Boiler, Flare, LTHW Distribution, CHP Engines x 2, Heat recovery Boiler.

Waste Water Treatment Plant – Treatment of redundant substrate, dewatering, aeration, scrubbing so that the substrate can be introduced back into the foul waste stream . (image on front page).

 

Quality

Northampton Biomethane Plant

Our approach to quality assurance is project specific and customer orientated underpinning our reputation as a leading International Engineering Contracting Group of companies. Don’t take our word for it; this is evidenced by 80% of our work being repeat business with existing clients as well as our Quality Management system being certified to internationally recognised ISO 9001:2015 standard.

 

Environment

We believe sustainable goals can serve as a catalyst for a continuous cycle of improvement which is why we take our role in environmental planning so seriously. We recognise that we have an important part to play in protecting and enhancing the environment for future generations and to help ensure the long term sustainability of the Construction Industry. There has been a global realisation that current development models are unsustainable and we are committed to embedding sustainability into the core of our activities.

We are accredited to internationally recognised ISO 14001 Environment Management System (EMS), a systematic framework to manage the immediate and long term environment impacts of an organisation’s products, services and processes. Of course, we don’t stop there. We work together at all levels to develop the correct attitude, practise and work habits, to ensure that we are continually improving our Environmental performance.
