Former teacher creates job and wealth by crushing bones to make animal feeds
By Special Correspondent
Isaac Njuguna’s workshop near the busy Dagoretti Market can be mistaken for one of the many abattoirs that dot the area. In the compound, a strong stench of rotting flesh and bones waft from the workshop, which is just a few meters away from the famous slaughterhouses of Dagoretti. In the populous Dagoretti area, slaughterhouses have been the lifeline of the locals, with most people eking out a living from the meaty business. The resultant booming business brings with it an undesirable byproduct; the bones, which are carelessly thrown about when people have feasted on the meat.
For Njuguna, a former teacher, the bones are a gold mine. He crushes them to make bone meal, an essential element when it comes to manufacture of animal feeds.
Since 1998, this has been his preoccupation. Though he earned a meager income when he worked as an untrained teacher, today he rakes in a handsome income from bones. His thriving business has created jobs for him and others in an area where most people are jobless.

Since 1998, this has been his preoccupation. Though he earned a meager income when he worked as an untrained teacher, today he rakes in a handsome income from bones. His thriving business has created jobs for him and others in an area where most people are jobless.
Here’s how he morphed into a job creator.
After completing his secondary school education at Meru School in 1983, he started working as an untrained teacher, where he earned a monthly income of Kes1400. Frustrated with the low pay, he q quit his job after five years and joined his villagemates in scavenging for jobs in the nearby Dagoreti slaughterhouses.
Once he got a job, he could work extra hard, to a point where he had saved enough to open his own butchery bin the nearby Ngong town.
It’s in Ngong town where he inadvertently bumped into the bone crushing business and liked it.
Though he couldn’t get enough information from the owner of the business about how to start such a venture, he was ingenious enough to create his own bone crushing machine from scratch.
With a bone crusher, he realized that he needed lots of electricity to run it. He almost gave up after he learnt that power installation could set him back with Kes400000.
Undeterred, he sold his meat business and took a leap of faith to venture into the bone crushing industry.
Once he took his first sample of bone meal to the Kenya Bureau of Standards for testing, it was given a clean bill of health, paving the way for more than two decades of bone meal production.
Today, he supplies the bone meal in bulk, to animal feed manufacturers like Hemco Feeds, Sigma Feeds, and Belfast Companies, some of which buy the product in batches of 2 tons, 5 tones or 10 tons.
His milling plant can process up to two tons of bone meal in a day. At any given day, the miller employs up to eight people, with the number rising to 12 when business is good.
Looking back, he delights in seeing the huge impact the bone business has had in his backyard.
“Bones from the slaughterhouses were disposed off anyhowly. Dogs would carry them farther and farther and the village would be drowning in the stench of rotting meat and bones.”
He believes that his bone factory is a way of ridding the village of bones, which can be a health hazard if not well handled.
Having achieved great success in the bone crushing business, he plans to set up a fully-fledged factory with a higher capacity as he aspires to meet the rising demand for bone meal.
As an old hand on the job, he has a few words of wisdom that can benefit young entrepreneurs. “Persist in whatever you do and you’ll’ ultimately reap rewards.”
For him, he says the stench of the rotting meat and bones is not so pleasant, but he persists to get money out of it all.

![Canon makes history with 170 Million lenses milestone Canon’s RF/EF lens production exceeds 170 million units, extending its world record in interchangeable lens production Both EF and RF lenses have gained strong support from a wide range of users—from beginners to professionals—leading to steady growth in production volume Canon Inc. announced that, in October 2025, Canon reached a historic milestone of producing a cumulative total of 170 million RF and EF interchangeable lenses for its EOS series, extending its world record for the highest number of interchangeable camera lenses ever produced. The EF lens was introduced in 1987 as the dedicated lens system for Canon’s EOS autofocus single-lens reflex film camera, debuting simultaneously with the EOS system itself. Since their inception, EF lenses have led the industry by incorporating a series of world-first technologies, including the Ultrasonic Motor (USM), Image Stabilizer (IS) technology, and a multilayered Diffractive Optical (DO) element, and have undergone numerous evolutions. In 2018, Canon launched the RF lens series, designed for the EOS R mirrorless camera system, which features a large aperture, short back focus, and high-speed communication system to deliver even higher image quality. The RF and EF lens series lineup now includes a total of 108 models , covering a wide range of focal lengths from ultra-wide 10mm to super-telephoto 1200mm. The series also includes the world’s first VR lens lenses with built-in power zoom suited for video shooting, and even those compatible with power zoom adapters—expanding the scope of creative expression and meeting the diverse needs of users for both still photography and video. EF lens production began at Canon’s Utsunomiya Plant in 1987. Since then, both EF and RF lenses have gained strong support from a wide range of users—from beginners to professionals—leading to steady growth in production volume. Today, Canon manufactures lenses at five sites: Utsunomiya Plant; Canon Inc., Taiwan; Canon Opto (Malaysia) Sdn. Bhd.; Oita Canon Inc.; and Miyazaki Canon Inc. Milestones include 10 million units produced by 1995 and 50 million by 2009. Then in 2014, Canon became the first company in the world to reach 100 million interchangeable camera lenses produced. In October 2025, the company reached 170 million units, leading to the achievement of this world record. The 170 millionth lens produced was the RF 70-200mm F2.8 L IS USM Z. Canon has maintained the No.1 global market share for digital interchangeable-lens cameras for 22 consecutive years since 2003. Moving forward, Canon will continue to refine its proprietary imaging technologies and further strengthen and expand its lens lineup, pioneering new imaging possibilities and contributing to the continued evolution of photographic and video culture. Highlights in the development of the RF/EF Lens Series The EF lens, which was introduced alongside EOS in March 1987, has adopted a variety of world-first technologies, including Image Stabilizer (IS) technology, featured in the EF 75-300mm f/4-5.6 IS USM released in 1995; a multilayered Diffractive Optical (DO) element, used in the EF 400mm f/4 DO IS USM launched in 2001; and Subwavelength Structure Coating (SWC) [7], applied to the EF 24mm f/1.4L II USM released in 2008. In 2021, Canon launched the EOS VR System, a VR video system consisting of a mirrorless camera [8], dedicated lens, and PC software, thereby creating a 3D 180° VR video through an interchangeable lens camera. In 2024, Canon began rolling out a new series of hybrid lenses equipped with iris rings, designed to meet the needs of both still photography and professional video production. For zoom lenses, the company has also launched RF 24-105mm F2.8 L IS USM Z and RF 70-200mm F2.8 L IS USM Z which are compatible with power zoom adapters. For single focus lenses, the company released F1.4 L hybrid prime lens series that unified the size and ring and button position across models. In September 2025, Canon launched RF 85mm F1.4 L VCM, the fifth model in this series, demonstrating that it can meet demands in line with the changing times.
