Corn silage 2016 -Resolve viscosity problems professionally with MethaPlus®


Corn silage yields with highly varied quality have been reported by the farming sector for the 2016
harvest. A large number of farmers missed the optimum harvesting time last autumn due to poor
weather conditions (including a dry and hot late summer). This has led to silage corn stocks that were
sometimes over-matured, with a tobacco-like odour. Dry substance values significantly over 40% and
starch levels that differ greatly were also not uncommon.

The use of these silage types causes problems in biogas production plant. Floating layers form and flow
and pump properties deteriorate. In addition to poor material transport and defective degassing, this
also leads to elevated plant energy consumption and increasing wear and tear on agitator equipment. In
extreme cases, major faults or production outages can occur.

MethaPlus® – A field-proven solution

Attempts to resolve this problem usually rely on water as a dilution agent, or the continuous operation
of the agitator equipment. Both approaches place an extra load on the systems and are not without their
risks (e.g. failure of the agitator) and additional costs. The excess water must be disposed of, and to do
so, the Chamber of Agriculture of North Rhine-Westphalia (LWK NRW) is currently estimating output and
disposal costs of 5 euros/m³.

The enzyme preparation MethaPlus® offers a field-proven and cost-effective method of resolving these
viscosity problems organically. DSM has many years of experience with MethaPlus® in the European
biogas industry and the company’s enzyme product boosts substrate conversion whilst significantly
reducing viscosity in the fermenter. As a result, total productivity rises, plant power consumption falls
and process stability is improved.
