In terms of the relations between growers and the washing stations, Rwandese coffee farmers expressed their satisfaction with the services provided.

Washing stations (where the pulp is removed from coffee beans) which are run by cooperatives can produce high quality coffee.

Then, the coffee is fermented overnight to break down the sugars.

MACT I was promulgated last April and covers pulping, bleaching and wastewater sources for chemical pulp mills.

The farmers feed the coffee cherries into a machine that removes their outer skin and pulp, which is known as pulping.

They bring the cherries down to the processing center for pulping and sun-drying, following traditional methods.

After picking, the grains are separated from the pulp (pulping), this operation is carried out using a rotary drum machine (“pulping machine”).

The US government subsequently improved its shredding techniques, by adding pulverizing, pulping, and chemical decomposition.

SOGESTAL Ngozi is a management company tasked with early treatment of coffee stations in Ngozi in which the State holds 26.9% of the capital.

The ecological unit is an innovative system that simplifies the coffee washing process through the mechanical removal of the mucilage when the coffee cherries are pulped.

Washing and de-pulping coffee cherries generates organic material that is not easily degradable and pollute the soil and water tables.

The pulping operation should also be done as soon as possible after harvesting to avoid any deterioration of the fruit which might affect the quality of the beans.

This is a long, more demanding task for the pickers, but it is necessary in order to remove the pulp and obtain the best quality bean.

Many farmers have invested the premium in pulping machines, used for wet processing their coffee on the farm.

The wet process consists of pulping and fermenting red cherries just after harvest by using machines that use water in the pulping process.
