Industrial IoT Case Study


Penn Waste Inc. Minimizes Machine Downtime and Improves
Efficiency with Cassia’s Bluetooth Gateways and Dodge’s Smart Sensors


Founded in 2000, Penn Waste Inc., a locally-operated and managed company focuses on providing South Central’s Pennsylvania with residential and commercial waste management services. The company’s recycling facility processes over 180,000 tons of material each year to promote a cleaner, more sustainable environment. Their strong commitment to environmental and social causes makes them the premier choice of residential and commercial waste management and recycling services in the state.


Penn Waste’s state-of-the-art recycling facility and modern equipment allowed the company to expand its sorting and recycling capabilities to process recyclables more efficiently and at a faster processing speed resulting in less contamination. One major challenge the company was facing was premature failure on their DRS glass breaker machine which is used to separate glass from mixed recyclables. These highly specialized machines are typically situated in very dirty areas of the facility where other items (i.e.,coat hangers, stringed bags, etc.) can get caught in the bearings and wrap around the bearing shaft causing damage to the seal. Consequently, this leads to the premature wear of the bearing and shortens its life span.

A second challenge Penn Waste faced was the manual intervention and ongoing inspection of these machines to ensure their optimal uptime. Oftentimes, several maintenance technicians would spend hours performing onsite inspections and cleaning the debris from the machines to reduce the risk of bearing failure.

When bearings would fail, additional labor was required to investigate the severity of the problem, disrupting many of their day-to-day business operations.


Penn Waste realized that it needed an advanced wireless solution combined with smart sensors that would deliver accurate, reliable and continuous real-time data for predictive maintenance. The company discovered an opportunity with Cassia Networks and Dodge Industrial and decided that the combination of Cassia’s X1000 Bluetooth Gateways, IoT Access Controller (AC) and Dodge’s Smart Sensors was the ideal solution to help overcome their challenges. The company’s goal was to continuously monitor the bearings of their machines to accurately predict failure without resorting to frequent manual inspection.

Long-Range, Multiple Device Connectivity

Penn Waste installed approximately sixty-two Dodge smart sensors on the DRS glass breaker machine to adequately cover all necessary bearings and gearboxes. In addition, two Cassia X1000 gateways were deployed in the area to continuously receive data from the sensors and send this data to the cloud. Cassia’s X1000 gateways provide long-range connectivity up to 1000 feet (in open space) and the ability to pair and connect up to 22 Bluetooth Low Energy (BLE) devices simultaneously. The long- range connectivity and ability to pair and connect multiple sensors simultaneously was a critical requirement for this deployment.

Simple, Scalable and Flexible

The combination of Dodge’s Smart Sensors, Cassia’s X1000 Gateways and IoT AC provided Penn Waste with a flexible and easy-to-use wireless solution allowing them to deploy at scale. The process of installing and commissioning the smart sensors took less than three minutes. Once the sensors were paired to Cassia’s gateways and a reliable internet connection was made, the gateways were able to seamlessly push data to the cloud. The simplicity of this wireless solution provided Penn Waste with the advanced tools they needed to access data anytime to proactively identify any maintenance requirements and prioritize labor tasks accordingly.


By using Cassia’s X1000 gateways, IoT AC and Dodge’s Smart Sensors, Penn Waste gained the real-time visibility needed to accomplish their objectives- reduce machine downtime, reduce overall costs and improve efficiency.

Reduced Machine Downtime

Before installing Dodge’s smart sensors and deploying Cassia’s X1000 gateways, Penn Waste would average nine bearing failures in a ten-month time frame. After installing the sensor gateway platform, the company has had zero machine failures and achieved a 95% uptime in machine performance. The ability to continuously monitor the temperature and vibration levels of the DRS assets provides the granular data and insights the maintenance managers need to accurately predict when and where problems were occurring. By taking a proactive approach to machine maintenance, Penn Waste was able to significantly reduce machine downtime and improve efficiency.

Significant Cost Savings

Since deploying Cassia’s X1000 gateways and Dodge’s Smart Sensors, maintenance managers can remotely monitor machine health without the need for frequent on- site inspection in these harsh environments. This allowed Penn Waste to ensure workplace safety and redirect labor to other mission-critical tasks in the facility. Furthermore, the predictive maintenance approach to machine monitoring allowed maintenance managers to address any equipment downtime issues to improve the overall efficiency of their assets and reduce any operational costs associated with repairing and/or replacing these specialized and costly machines.

Maximizing Uptime for Improved Business Operations

For Penn Waste, managing and maintaining complex and costly equipment and processes is crucial for not only running the business efficiently and safely but also for meeting and exceeding the business’ bottom line. By installing Dodge’s Smart Sensors and Cassia’s X1000 gateways, maintenance managers have around the clock real-time visibility into asset performance resulting in maximized uptime for their machines, improved business operations and a greater ROI. By integrating predictive maintenance into their wider digital maintenance strategy, Penn Waste has captured the value from both increased uptime and reduced maintenance and labor costs.

Cassia’s X 1000 gateways were simple to use and install and stood to the test in these harsh environments as well as providing the long-range connectivity we needed. What one wants from any wireless technology is dependability, efficiency and durability. Cassia’s gateways and Dodge’s smart sensors have given us just that.
