MetGen’s enzymatic solutions – marketed under registered trademark MetZyme® - provide large industry sectors with a wide range of environmental benefits.

While fulfilling customers’ (otherwise unmet) performance requirements, at cost points in-line with more established enzyme peers, MetGen’s solutions provide a broad range of sustainability and operational benefits, in particular, energy savings, higher yields, improved product and less waste.

In pulp and paper, MetZyme® boosts profitability and sustainability by reducing energy and chemical consumption as well as improving end-product quality. At the same time, the impact in carbon footprint is significant. Enzymatic technologies are a natural way to reduce dependence on harsh chemicals or over – processing while improving the process – economically, technologically, and environmentally.
MetGen’s enzymes contribute to the development of affordable sugars and renewable biochemicals from cellulosic feedstock. On its part, MetGen paves the way towards affordable 2nd generation biofuels and bio-based chemicals, hence enabling a paradigm shift in the chemical industry to move away from petroleum and change over to renewable biomass.

Lignocellulosic biomass – a variety of non-edible, woody materials – is the largest renewable reservoir of fermentable carbohydrates, aromatic compounds, and other chemical building blocks. It is composed of cellulose and hemicellulose embedded in lignin. The MetGen technology platform enables further improvements in the bioconversion of all parts of lignocellulosic biomass into value-added chemicals, including biofuels.
We at MetGen thrive to minimize the environmental footprint and reduce our customers’ dependence on fossil fuels by increasing production yields with reduced costs and energy consumption – making more out of less.

MetZyme® is a label of Quality & Sustainability.

Life Cycle Analysis (LCA)

LCA and KPIs for enzyme production (PDF report)

As a solution provider, MetGen is an enabler of improved sustainability across its served value chains, and fully embraces this role. In November 2016 MetGen had a cradle-to-gate life cycle analysis (LCA) review completed by Gaia Consulting, based on ISO-14040 & 14044. This effort reflects MetGen’s ambitions to improve and facilitate environmental impact assessments and decision-making for companies using their enzymes. Gaia conducted the analysis on two customer cases:

Example 1: Thermomechanical pulping

  • Energy intensity of TMP primary refining was reduced by 12.5% when refining to a constant target freshness in a mill trial using MetGen enzymes.
  • As such, the CO2 emission intensity dropped 84kg/ton refined. This means an annual CO2 emissions reduction of 25,000 tons for a mill with a yearly production of 300,000 tons.
  • In addition, relevant favorable fibre properties were also analyzed.

Example 2: Tissue production

  • Production efficiency was increased by 8% due to an increase in the speed of the paper machine as well as lower break time, without any increase in drying temperatures.
  • As such, the lower specific energy consumption, per MT produced, allows a reduction in CO2 emissions in the same proportion.
