macadamia nuts supplier & producer

Macadamia nuts & More from smallholder farmers

LIMBUA is a German-Kenyan macadamia nuts supplier & producer without intermediate trade. That means: You buy directly from the manufacturer. In cooperation with over 7000 Kenyan smallholders we produce macadamia nuts, macadamia oil, avocado oil and dried mangoes for the trade. This way you can be sure that our products are of high quality and come from a trusted source. All our products are available in bulk, freshly harvested from the farms and processed directly on site in our modern production facilities.


In this video you can watch the journey of the best macadamias: from cultivation to harvesting to processing. The nuts are gently dried raw using a specially developed process. We are a leading global nuts supplier of organic macadamia kernels and supply the best quality organic products with multiple certifications.  As you buy directly from the producer without any middlemen, this naturally has a positive effect on the price. At LIMBUA, it's farm to fork!


We process macadamia nuts, avocados and mangos entirely locally so that as many people as possible around Mount Kenya can benefit.

Thus, four production sites have been established in the countryside in the course of LIMBUA's development as a leading macadamia nuts supplier:

GITHURE Macadamia processing
KITHUNGURURU Macadamia processing
KATHANGARI Our nursery
KIANYAGA Macadamia processing  
ENA Avocado oil factory

That means:

Close to the local people
Short transport routes
Fresh raw material
Improved standard of living for the rural population



The story of LIMBUA began in 2006 with a long journey: After studying economics at the University of Witten/Herdecke, Matti Spiecker was inspired by successful social entrepreneurs in Asia, Latin America and Africa. In Kenya, he met Peter Muchau Wangara. They developed the idea for a trading company specializing in organic macadamia nuts.

Without middlemen, the two managing directors wanted to bring the harvest of Kenyan smallholders to the international market, leaving as much added value as possible in the country. For the customers, this means being able to buy macadamia nuts directly from the producer - without intermediaries. Because from the very beginning, LIMBUA has been in charge of production and distribution.

Our way there

Since day one, LIMBUA has been about sustainable business, focusing on ecological and social aspects.

  • 2006

    While the company idea grows, the foundation WELT:KLASSE starts its work. It gives students the chance to get to know sustainability projects in Kenya and other countries.

  • 2009

    LIMBUA is founded as a German-Kenyan company specializing in organic macadamia nuts. A processing facility is established in Githure to process the harvest locally.

  • 2012

    After 3 years of conversion, the first smallholders receive full organic status. LIMBUA is therefore the first company in the world to accompany macadamia smallholders in achieving organic certification.

  • 2014

    There is an increasing demand for macadamia nuts in organic quality for natural food and cosmetics. LIMBUA grows and opens its second factory in Kithungururu.

  • 2016

    Well-known companies from the German and European organic market are now among LIMBUA's customers. To serve them, a third factory is built in Kianyaga.

  • 2018

    For more and more customers LIMBUA is considered a quality producer of organic macadamia nuts and thus the factory in Kithungururu is expanded to meet the increasing demand.

  • 2020

    The increasing demand ensures full capacity utilization in all three processing sites. Ideas are developed to bring more organic products from Kenyan smallholder farmers to the market.

  • 2021

    LIMBUA expands its product range with avocado oil. For this product, too, a modern factory is built on site, where the fruits are peeled, pitted and cold-pressed.

  • 2022

    Organic mango is now also being purchased from the farmers who work with LIMBUA. The fruits are processed into dried mangoes of organic quality.


Today, LIMBUA is the leading nuts supplier of organic macadamias. With fresh ideas and modern technology, we are turning the world into a village: harvest recording, quality control and logistics have long been digitized at our company. This allows us to pay our macadamia farmers fairly, in real time and keep track of the journey from farm to customer. And the custumor can buy macadamia nuts and more in the highest quality. 

In addition to raw kernels, we also supply roasted nuts, nut butter, nut oil, avocado oil and dried mangoes for wholesalers and processors. All products from our own production and harvested by local farmers.

When the added value stays in the country, more people benefit from Fair Trade. This idea guided me in founding LIMBUA.
