vinasse

Effects of two beet vinasse forms on soil physical properties and soil loss.

The final byproduct, vinasse, is used as fertilizer or growth substrate for yeast cultures.

One use of vinasse is in thermophilic digesters.

Furthermore, vinasse is sometimes mishandled in storage and transport in mills.

For each unit of volume of ethanol, about eight units of vinasse are produced.

Before evaporation, the juice is filtered once again, producing vinasse, a fluid rich in organic compounds.

After the removal of the desired product (alcohol, ascorbic acid, etc.) the remaining material is called vinasse.

In Brazil, this kind of biodigester is used to process vinasse as a cheap source of methane.

Molasses-based distilleries all over the world generate large amount of effluent termed as spent wash or vinasse.

The alcohol passes into the distillate area where it begins preparation, through columns whose primary function is to purify vinasse.

Despite this ban, some small sugarcane mills still discharge vinasse into streams and rivers due to a lack of transportation and application resources.

In Brazil thermophilic digester is a source of biogas using pure and hot vinasse as the source of production of methane.

Commercially offered vinasse comes either from sugar cane and is called cane-vinasse or from sugar beet and is called beet-vinasse.

Legislation has banned the direct discharge of vinasse onto surface waters, leading it to be mixed with waste water from the sugarcane washing process to be reused as organic fertilizer on sugarcane fields.

The two greatest sources of water pollution from ethanol production come from mills in the form of waste water from washing sugarcane stems prior to passing through mills, and vinasse, produced in distillation.

In the past, vinasse was a problem in production of ethanol, but vinasse is also a good fertilizer (at least for some time) and a source of methane that can be used to generate heat or electricity.

Given IMSA's strict adherence to a sound environmental policy, Manuelita's ethanol production process is geared to produce as little vinasse as possible (2 liters of vinasse per liter of ethanol vs. 12-20 liters of vinasse per liter of ethanol in standard plants).
