We often talk about “comparing apples to oranges” But what if we choose not to compare but to create something out of oranges. “Yeah…duh.”, you say. But we know that oranges give us a juicy pulp which we could eat or convert into that classic, coveted orange juice. True. But then what do we do with the peels? A story is told of two people who needed to share an orange for their needs by cutting it into halves.
When we think of circular agro-processing, we imagine producing value-added products from agricultural produce devoid of waste. And there’s something magical about converting waste into value… It generates new incomes and creates new possibilities. And to this end, the coconut is exceptional. Let’s take a deepdive into the world of coconuts.
I gulped the remaining chilled mango juice which really quenched my thirst in the hot weather. Temperatures were beyond 40 celcius. I just had lunch at a friend’s restaurant and the icing on the cake was a glass of sweet, chilled mango juice. I’ve always had a love for mangoes. While growing up, we had two humongous mango trees just outside our home and they really delivered the goods when needed.
While growing up, we’ve always been warned against the dangers of eating excessive fat. Why? Because it may lead to cardiovascular problems. But is fat all that bad? Well, the story today is sort of flipped. Many online articles talk about the health benefits of animal fats like ghee, lard, or tallow. So I ask myself…what changed? Well, nothing has changed.
It’s a new year everyone. Mine is to thank you for subscribing to this blog/ newsletter. The goal of this publication is to push us towards circularity and sustainability as we engage in our daily lives. As we start the year, I’d like to embark on another sustainablity expedition by exploring agroprocessing. What comes to mind when this catch word is mentioned?
Nothing in the natural world gives us the picture of a full cycle of life like composting. Composting is simply breakdown of complex plant and animal remains into simpler substances that can be assimilated by plants. Composting usually mimics humus formation in nature – conversion of fallen leaves into compost. However, it may take over six months for the final product, which is quite some time.
At some point, I thought that my lemon verbana vine was dying off. The leaves had withered, and it had lost its scent. But something happened when the rains started. I noticed a vibrancy creeping in. Infact, it wasn’t just about the verbena vine. I noticed other herbs and flower plants developing a greenish tinge… Their stems started having protrusions which later developed into buds, then flowers.
When William Ruto started off on the campaign trail for his quest for presidency, he carried the hopes of many people. Many cast their ballot in his favor because he seemed believable. He seemed to connect with the ‘ground’ in ways his main opponent couldn’t. He brandished his faith as badge of honor that lured many religious folk to his fold.
Plastics generate interest because they are easy to make but very difficult to degrade leading to a plastic solid waste catastrophe. Most plastics are a by-product of petroleum refining, which make their presence a guarantee as long as we use fossil fuels. Some might say that we can recycle plastics into other products like building blocks, diesel etc However, is this form of recycling- also called chemical recycling- really sustainable?
The thing with beef tallow is that it turns waxy immediately it’s removed from the flame. Wax, as we know it, it hard. And that’s exactly what we are looking for when we want to make bar soap. Combine hardness with good foaming, and you have a superb soap bar that can serve you for ages. And that’s what we shall be talking about here.
Now, try poking your nose into a cauldron of simmering beef fat and you’ll understand what the title of this article means. Beef tallow is a superb product but has that distinct stink that seems to be worse than that of normal beef. This reality prevents many people from utilising this product. But this shouldn’t stop us from enjoying this golden niceness.
I called a connection who would link me up with a unique butcher – one who sells beef fat. The next day, I linked up with him, bought some meat then he led me to a backstreet to some ladies who sold beef fat. They named their price and I thought it was a good bargain so we struck a deal. I bought 5kg of white beef fat most of which is derived from around the organs like kidneys.
Potato chips colour our parties. They are the go-to meal when we just want that fast filling, sumptuous and easy to fix snack. A few of us like to cook potatoes with the skin. But for those of us who peel them, where do we dispose of these wastes? Well, there are a few places where peels could find use. Composting them helps return their nutrients back to the soil… Incorporating them into animal feeds helps enrich livestock diets.
You sow those seeds and after 3 months, 6 months or a year, you get a bumper harvest. “I’m smiling all the way to the bank,” you say. But is this all you can reap from your crops? After making money from the produce, what about converting the waste into valuable products to make more money? UPCYCLING Upcycling is about taking what’s considered as not valuable and converting it into what’s valuable.
It’s OK to dream. But it takes more to start moving towards achieving it. Too often do we let ideas bounce off our heads without action. But have you ever thought of picking up and running with that one idea to its logical end? Well, it’s good to be a think tank – churning up those ideas per minute. But it’s better to pick one or two and create something out of it.
Upcycling is an inescapable phenomenon when thinking about sustainability. But what’s upcycling in the first place? Let me attempt to explain… SPENT TYRES A brand new car tyre could cost around USD 50 in the Kenyan market. So what if – in a worst case scenario – this tyre is roughed up within a span of a month or two (given the bad state of our roads)?
There’s a saying,”What goes round must come around.” And this reality is best illustrated by composting. We’re all affected by the stuff we dispose around us. But we have two choices… The worst case scenario is that stuff – waste – makes our environment a living nightmare. Picture rubbish strewn all around our neighborhood.
Biogas is simply natural gas derived from rotting organic waste. These include kitchen waste, fresh livestock manure, human faeces among others. Biogas production heavily depends on very minute players in this great energetic gallery. BACTERIA Bacteria used to convert organic waste into biogas are mainly derived from runinants. Their guts have the right mix of biology that breaks down complex stuff like cellulose into simpler substances like methane – natural gas.
The circular economy isn’t just about generating value from waste. It’s also about making the best out of the worst – pollution. And environmental pollution doesn’t come packaged worse than toxic heavy metals. TOXIC HEAVY METALS These substances are not only toxic. They also cannot be destroyed or degraded. They are in their simplest form and that’s the form in which they can do maximum damage.
You might not believe it but this article is about my business plan. I’m willing to share it with others simply because the market has room for all of us – the bottom line is how the product is packaged.
What if we were to produce products with health benefits using principles of circular economy? Better still, what if we extract health-boosting substances from what’s discarded as waste? The circular economy avails to us opportunities to exploit in this regard. Here are some few. BEEF TALLOW What happens to excess fat from animals after slaughter?
Phosphorus is a unique substance. It’s one of the three most important macronutrients needed for agriculture yet it’s the only one among the three that is mined. Most of global phosphorus is mined in Morocco and the Western Sahara Republic – which Morocco has laid claim to for decades.
The police land-rover stood imposingly next to her. A male police officer grabbed her, manhandled her and tossed her in the vehicle. She tried to make her views known… ‘YOU KILLED MY SON. NOW YOU ARE ARRESTING ME…’, she yelled.
Look… I do not agree with the leadership of President William Ruto… He has allowed cronies and tribesmen to mismanage government agencies… He doesn’t seem to have clear numbers about our debt and what ought to be paid… He seems to be letting police agencies abduct people with some of them losing their lives… He […]

I walked into a government testing lab for some analysis. I expected the cost to be Kshs 2500 per sample. However, the government official told me that this time, he would charge me Kshs 2000 per sample. I was elated…at least he was giving me a generous discount because I was a repeat customer.
Are there any modern day prophets? In the first place, who were the prophets of biblical days? A scan through the old testament of the Bible reveals a struggle…the plight of the nation, Israel. A nation that had been chosen by God yet themselves chose not to follow this God who had chosen them.
In 1986, a tragedy took place in the Cameroonian village of Nyos. The village was located close to a lake by the same name, Nyos. Now, Lake Nyos was on the surface, an ordinary looking lake surrounded by mountains in the scenic Cameroonian countryside.
You’re standing in a queue waiting to be let into an establishment. There is commotion, a melee and a scramble. This is an event you’ve coveted for ages and here’s a chance of a lifetime to be part of it.
‘A hundred shillings a kilo’ was the answer. I was at a butchery near our local slaughterhouse inquiring on the cost of beef fat. The butcher stuck to his price, though I knew that if I came prepared with the money, he would back down a bit.
It was my first experience with e-commerce and the product did not dissapoint. I had just received a Google Chrome notebook which costed less than you can imagine. It could flip over and convert into a tablet and had a touch screen besides other functionalities.
I offloaded the sack in my storeroom. Now I had fuel that could last me for weeks. You see, charcoal is our most common fuel in Africa. And as an ardent African, I would not disappoint. The charcoal sack weighed probably slightly over sixty kilos.
‘We buy used motherboards’, the gentleman stated. At that point, I tapped the shoulder of one of my students as I hinted to him about this business opportunity. As a lecturer, I occasionally expose my students to industry and this was such a time.
I drove the nails through the roof, descended from the ladder and entered my living room. I had been nailing some solar panels onto my roof. I checked the battery, inverter, charge controller and the multiplug connected to the lights and other electronics. I was satisfied.
I once stumbled upon a video of a guy making fun of a friend who had been eating rice and beans for nine days in a row. Well, probably he had been enjoying the best burgers or pizza or fine dining. So that made him quite surprised about the friend’s predicament.
I’m just from teaching a class of environmental chemistry. So what I’ve done over the three hour class period is to share my presentation for about an hour then allow a group to present some work they’ve been researching on for about 3 or 4 weeks.
Consider the individuals enduring the pressures of life, navigating through challenges and adversities. Envision men and women striving to secure employment… Struggling to make ends meet… Facing difficulties in their marriages… Juggling demanding work responsibilities… Endeavoring to meet others’ expectations… Struggles upon struggles.
Picture this: you’re standing at the edge of a rickety, old bridge. The planks are rotting, the ropes are frayed, and every step you take sends a shiver up your spine. Welcome to the bridge of toxic relationships and addictive habits. It’s a marvel that you’ve made it this far without tumbling into the abyss.
I remember when the prices of edible oils skyrocketed in an instant in my nation, Kenya. Consumers were out of options since the big players in this sector have such an iron grip on the market. Well, the government tried to intervene and to some extent, prices seemed to stabilise.
A quick visit to your local butchery reveals a very unique type of waste – animal fat Most of it is possibly sold to pet owners or thrown away altogether. But what if this fat forms a raw material for manufacturing of something we use several times in a day?
I’ve always toyed with entrepreneurship ideas. I’ve tried some out with a measure of success (and equal measure of failure) while others have just lingered in my mind. I often note down ideas that cross my mind on my phone, notepad app… and it’s been helpful.
Batteries, often overlooked in discussions about AI, play a pivotal role in powering the devices that are shaping our future. From smartphones to autonomous vehicles, the seamless integration of AI relies heavily on advancements in battery development.
In our world, taking care of the environment is super important because things have become really urgent. Businesses can actually make money while also helping the planet. Imagine a big city with tall buildings – it looks cool, but there’s a problem.
