How can traceability improve the quality and safety of the manufacturing process?
When confronted with a buying decision, customers don’t just look at the price or the label of the product to make up their minds, there are 2 factors highly considered in this process: Quality & Safety.When we talk about LPG cylinders, these 2 attributes can’t be overlooked, because the lives of the people depend on them!Some nations like Tanzania, Ivory Coast, and Ghana had their share of suffering after massive LPG cylinder explosions in a record time, leaving a question mark about the manufacturing process.The truth about this process is that it can only be measured, tested, and rated; monitored, improved, and sustained by the traceability process!Read more https://www.linkedin.com/pulse/how-can-traceability-improve-quality-safety-manufacturing-/

We care about the environment and the well-being of the people.
Without initiatives, leaders are simply workers in leadership positions.Sigma Cylinders, under RJ Group Holding, has taken the shift towards clean energy and deforestation to a groundwork level where we have visited rural areas in East Africa, granted full sets of 6Kg cylinders to homes, and guaranteed the spread of LPG education and awareness among the beautiful families we have met. Sigma Cylinders took another great initiative in changing the whole environment for those families by replacing their homes with new ones having a fresh healthy start. Six new houses are on 60% of construction with expected delivery in 45 days. We operate in Africa and we will always assist in African growth and development.

We recycle.
“Sustainability” is a pillar of our corporate strategy. In our core business, we have adopted the notion of facilitating the shift towards clean energy. But we did not stop here. We have also developed and implemented a strict recycling policy in all our manufacturing processes across our four plants Lebanon, Ivory Coast, Ghana and Iraq.As a first step, we have prepared a Recycling Program and determined the types of recyclable materials that are being discarded and the approximate volume per week and month. We have identified that we can recycle steel, nylon, wood, plastic, paper and water.Now, we are separating and capturing the recyclable material in dedicated recycling bins at the best locations to accommodate the collection process. We continuously talk to our employees to get their feedback on any suggestions for improvement.As with any program, our initial objective is to build the right habits quickly and try to blend the program with Sigma Cylinders corporate culture, employees, and existing routines as much as possible so that the new habits are much easier on the entire organization.Last but not least, the money collected from the recycling process, is given back to our communities through local charity organizations.
