During my rourine field inspection to food premises in Kisumu County, Kenya, we visited Coca-Cola- Equator Bottlers Limited in Kisumu to witness how food hygiene was applied in a large scale supply industry. The bottling firm prepares in large scale: soft drinks (soda) and mineral water. The firm has two production lines: Recycled glass bottles (RGB) and Plastic bottles (PET). Raw materials include: Externally sourced concentrate as patented formula Crowns and closures Imported glass Water sourced as raw water from Lake Victoria and treated at the firm Fine grade white sugar sourced from Egypt and Saudi Arabia Caustic (NaOH) for washing glass bottles Chlorine disinfectant Gases e.g. Nitrogen, Ammonia ,ozone ,Carbon(iv)oxide All incoming chemicals and devices are inspected for conformance with specs required. Preparation a) Production of RGBs Dirty glass bottles are taken to a warehouse where they are sorted according to brand and cleansed; they are then brought in crates to the production hall. A machine empties the bottles from crates in the depalatizing area followed by pre-inspection of bottles, carried out by visualizing checking for cracked bottles. The bottles are then dragged via a conveyer belt to the washer. In the washer, a bottle is passed through hot water, into a 1st caustic tank then a second caustic tank. The bottles pass through chlorine disinfectant before a final rinse with water at 80°C. This process takes about half an hour. The clean bottles pass through a siting station, where dirty bottles, foreign bottles and cracked bottles are removed. The bottles move to an Electronic Bottle Inspector (EBI) machine that spots and automatically removes bottles with faults but passed the siting station. The clean, inspected bottles move to the filling machine with pre-prepared formula for specific brand. 60 seconds after filling, the bottles are crowned and date coded as they pass a siting station where proper crowning, filing and date coding has been done before palatizing is done for storage. b) Production of PETs PET bottles are used for products such as juices, soda and bottled water. PETs come as imported pre-formed shapes that are moulded on- site. In the production hall, the Pre-formed shapes are heated and blown into required moulds. They pass through siting stations through the EBI for fault identification. The ready bottles are filled and date coded and capped using plastic closures. They are then stacked in polythene covered palates for storage before distribution.

Hello Okoth!
It's your SJ mentor.
I hope you are doing well.
Thank you for writing an article about your useful experience and sharing with us.
In a recent news, I heard that Coca-Cola PET bottle is the world's No. 1 plastic waste.
It is said that they are developing paper soda bottles to solve these environmental problems.
Glass bottles and pet bottles are recycled, but they are often not.
I wonder how to recycle broken glass bottles.
I think it will be melted again and reprocessed, but I think it would be nice if you could also talk about this.
Green cheers!
Sincerely,
SJ mentor.

Hello Okoth,
this is your mentor WooJoo.
Warm greetings from South Korea!
Thank you for sharing your experiences of visiting CocaCola -Equator Bottlers.
Your report has introduced us well about how RGBs and plastic bottles undergo in industry processes in detail,
which I never got the chance to hear about.
I wonder what the RGBs are filled with, and how much is the RGB production compared to new plastic bottles, which is very important factor to know how well we are recycling, and how the industry is trying to reduce the use of plastic.
It would be very nice if you can tell us statistics related to the processes too.
Keep sharing
Regards,
WooJoo
