Bio-organic catalyst (BOC) dosing unit live in Northern Ireland

Alps Ecoscience is pleased to announce installation of another bio organic catalyst (BOC) dosing unit at an Anaerobic Digester plant in Northern Ireland. This is one of a number of new relationships developed by Clinty Chemicals, Alps Ecoscience’s BOC distribution partner across Ireland. Clinty is Ireland’s longest serving water treatment chemical manufacturer. They manufacture and distribute best in class water remediation products, and provide waste management solutions to the industrial and municipal markets.

Bio-organic catalyst in Anaerobic Digestion (AD)

A high lignocellulosic feedstock such as maize or crop residues can be difficult to fully digest during the AD process. Resulting in sub-optimal digester performance; lower gas yield, longer HRT and lower digestate quality. The fibrous structure of most lignocellulosic feedstock requires a combination of technical solutions; both mechanical and biochemical to access their sugar and starch. Even then enzymatic hydrolysis can be a limiting step to full degradation with these complex feedstock. The key to unlocking their potential and maximing energy release is increased enzyme efficiency. The bio-organic catalyst is an enabler here, with its unique ability to catalyse and solubilise.

  • Catalysation: Reduces the amount of energy required for biological or chemical reactions to occur, then participates repeatedly in these reactions while reducing the time and rate required for turnover (accelerates nature’s degradation process 100-fold faster).
  • Solubilisation: BOC solubilises the cellular structure of organic waste, thereby increasing gas transfer rates, and making it easier for naturally occurring bacteria to digest organic substances and oxidising agents to work.

Practical and cost effective deployment

Adoption of bio-organic catalysts is increasing amongst AD plant operators because of the flexibility it provides when managing feedstock. It simplifies the processing of high lignocellulosic feedstocks and enables a greater variety of mixed organic waste. This has proven commercially attractive during the pandemic as feedstock availability and cost has fluctuated. The added advantage of bio-organic catalysts is their ease of application. They are simply pumped directly from an IBC at a bespoke flow rate into the appropriate stage in the AD process. This can be into pre-treatment tanks, digester chambers, recirculation pipes or digestate storage tanks depending upon the issue the BOC is tackling.

In this instance, the BOC dosing unit, seen in the foreground of the main picture (above) is sitting directly above the pre-mixing chamber which is below ground. The installation involved drilling into the concrete cover and installing a flow pipe from the BOC doing unit into the mixing tank. The installation was preceded by a series of lab tests to analyse the digester performance and establish benchmark indicators. Typically the catalytic effect begins to take effect within 24 hours and starts to yield output benefits with 7 days.

Early site reports on the BOC dosing are positive, with visible changes in biological activity being observed in the pre-mixing tank. The temperature in the tank has increased to 24.3C with no external heat source and the video below shows the increased fermentation activity.
