WEIGHING FOR STATISTICS
Swedish municipalities are responsible for their own household waste and are able to affect the amount of produced waste through proactive environmental work. Through their efforts, the amount of waste can be reduced and material recycling improved. With mobile weighing and RFID-systems connected to the ERP of the municipality, they get in total control of the process and benefit from detailed statistics of the collected waste.
More than 170 councils in Sweden, from Kiruna in the north to Trelleborg far south, have introduced automatic identification of household waste with RFID. The system consists of a RFID-tag with a unique identity that is mounted on the bin, and a RFID-system in the vehicle which records the collection in real-time as well as the GPS-coordinates of the pick-up point.
The information is linked to each customer in the CRM through a software that transfers the data to the business system of the municipality. All information is transferred, for example collection address, fraction, size of the bin and timestamp, giving the municipality total control of the number of bins in use, where they are, and that every customer gets the right service for the right cost.
When introducing this technique a lot of errors are often detected, such as wrong collection frequency, wrong bin size or surprisingly high amount of bins that are emptied each week despite not having a subscription.
MOBILE WEIGHING PROVIDES VALUABLE STATISTICS
Automatic identification can be combined with weighing the collected waste. The scales are integrated in the lifter of the vehicle and the weight is automatically recorded. The weighing system, containing load cells, connection equipment and a weighing instrument, is connected to the RFID-system. The weight of the waste is connected to the unique RFID-tag of the bin, and by that also to the customer. The weight and associated data is recorded and displayed in the route software in the vehicle, and transferred to the business system of the municipality. The weighing systems are dynamic and do not affect the lift cycle, eliminating any time losses related to weighing.
“European Union’s goal is that 65% of the household waste goes to material recycling”
Weighing the waste in each bin and at each customer generates detailed statistics that can help to facilitate the collection process and the progression of waste management in many ways.
