A waste management collection company was experiencing multiple challenges within its motor dealership customer base which is spread across various provinces within South Africa. These challenges were centred around the collection of waste oil from the various dealerships and could be summarised as follows:
Theft of the waste oil. A black market exists for second hand oil in South Africa and it was clear that thousands of litres of oil was going missing from various sites which correlated into significant financial losses. Without real-time insight, it was impossible to determine where the theft was occurring i.e at the dealership level or between collection and drop off.
Overflowing of waste oil at the dealerships. This could be attributed to the reliance on manual notifications between the dealerships, the waste management company and third party collection vehicles. Not only did this result in emergency call outs, incurred costs for clean up operations and fines from the relevant authorities, but also resulted in strain strained relations between the company and its clients.
Inefficiencies in logistics. Due to a lack of real-time insight into waste oil storage vessel fill levels, the collection of waste oil was performed on an adhoc basis based and on assumptions or manual notifications from the various sites. This had a direct impact on the efficiency of the logistics of the operations with time and fleet management cost implications.
Through the installation of ultrasonic sensors into the waste oil collection vessels, we were able to implement upper and lower thresholds that allowed for proactive alerts that would prevent an overflow scenario as well as provide insights into theft. For the first time, the waste management company had actual data to validate how much waste oil should be collected and could validate against third party logistic company records to eliminate losses. Over and above this, the company could utilise the route planner to dispatch its service providers according to the most efficient route and only visit dealerships that had reached the upper threshold limit.
Significant financial benefits are being realised through the elimination of theft and efficiencies derived in the collection process. i.e saving on manhours, fuel costs and reduced vehicle maintenance requirements.
