The pellet of olive oil marc, a biomass still very little known to the public.

 

From October to December, the olive oil production season takes place in the oil producing countries, but during this time a large amount of waste such as olive pomace emissions are generated.

Releases consisting of skins, pulp residues and core fragments – and margines, mixtures of oil and highly polluting water loaded with organic matter.

Sometimes they get rid of them by throwing them out into the wild, but more often the owners of the presses sell the grignons for composting on agricultural land.

The chemical composition of the grignons and the large tonnage released constitute pollution for fragile regions, thus, incompatible with the principle of sustainable development.

Some producers already have a recovery scheme but the proportions treated are relatively low compared to the relatively large ratio. The virgin olive residue is obtained by machines called “core sorters”. Solvents or other chemicals are not used with this system.

The extraction process is generally carried out in the press. Olive pomace or “olive residue” is a fuel with high calorific value and completely ecological which can be mixed with wood to make pellets.

This woody biomass fuel is considered to be plant material produced only by mechanical processes of transformation of agricultural products, without adding 100% chemical and ecological additives.

It is economical, and always available in abundance which, in addition to having a high heat output, considerably reduces the production of smoke and ash, which means for the boiler a longer service life and less maintenance.

The low humidity (5-10%) optimizes combustion and allows more heat to be released. The calorific value of a briquette is practically 5 kW or 19 MJ / kg, which is higher than what any conventional so-called dry firewood that still contains 20% moisture offers, despite two years of drying.

Here is an innovative and little known to the public means of heating ecologically while contributing to the circular economy.
