What does "CEDRE" mean?

CEDRE is above all an international expert in accidental water pollution who has been active in France and abroad for nearly 40 years.

CEDRE is also a public service body approved by the French State, whose mission is to provide its advice and expertise to the French and foreign private authorities and structures in charge of the anti-pollution response.

At GREEN KEEPER AFRICA, we wanted to certify our absorbent because it is:

  • A benchmark of trust for our customers
  • A sign of quality and safety, controlled by an independent third party

How to store Green Keeper Africa products?

Our absorbents are stable products. However, they should be kept away from moisture.

To be able to respond to emergency situations, it is necessary to build up a stock in advance. This must be defined according to the accident situations to be faced (scenario study).
The types of products to be selected and the quantities to be supplied depend on the type of situation considered, its frequency and the importance of the interventions.

Should I always buy PPE when I order a kit?

No. We offer ready-to-use kits to meet your needs and offer you turnkey solutions. If you already have PPE or if you do not wish to buy it, let us know when you request a price quote and we will offer you kits without PPE.

What to do with the sorbent once used? What are the different options for recycling GKA sorbent after use?

Our GKSORB® sorbent can be incinerated after use.

In Benin, our partner ECOCLEAN, a specialist in waste management, collects the soiled absorbent on your site. The absorbent is taken to our Green Keeper Africa depollution site. The waste will then be sorted, classified and dried in order to transport it to the disposal site by incineration in a cement kiln.

What will it cost me to treat the waste?

Contact us so that we can study together the possibilities for the treatment of contaminated absorbents and make you a proposal adapted and personalized to your needs and constraints.

What if I put some sorbent in my eyes?

Our products are 100% organic and natural. In case of contact with eyes, rinse immediately with clean water.

Won’t you end up having to grow this invasive plant to keep your activity in place?

The replication capacity of hyacinth is such that we do not need to cultivate water hyacinth.

In a few figures:

1 plant produces 600,000 plants in 8 months,
1 produces 2,000 seeds per year,
1 seed is viable between 5 to 20 years!
Water hyacinth is classified as the most invasive aquatic plant in the world! (Source IUCN)

And since a picture is worth a thousand words….

What is the local benefit of your activity? What impact does Green Keeper Africa have on the environment?

At the social level:

The Green Keeper Africa impact assessment report prepared by SENS (Solidarité Entreprise Nord Sud) in June 2017 highlighted the benefits that collectors have been able to derive from their collaboration with Green Keeper Africa:

  • An average income obtained from the collection of water hyacinth, which is 31,180 CFA francs, which is higher than the SMAG (Agricultural Minimum Wage) which is 30,000 CFA francs;
  • Better coverage of children’s school fees;
  • Reducing the use of external resources (loans and other) to cover various expenses and contingencies.

At the environmental level:

The activity of Green Keeper Africa made it possible to collect 25 tons of fresh water hyacinth in 2016, which corresponds to 2 football fields!
