E-waste, or electronic waste, refers to any discarded product that contains electrical components or circuitry. This includes everything from large household appliances to small electronic devices like smartphones, cables, and batteries. In the context of logistics and supply chains, it also includes the millions of single-use electronic dataloggers discarded every year after just one trip.
Understanding what qualifies as e-waste matters because improper disposal of electronic products releases toxic materials into the environment, and the volume of electronic waste generated globally continues to grow. The sections below break down the key questions around e-waste, including why certain supply chain tools contribute to the problem and what alternatives exist.
What types of devices count as e-waste?
E-waste includes any item that has a battery, plug, or electronic circuit and has reached the end of its useful life. This covers a wide range of products, from large appliances like refrigerators and washing machines to smaller consumer electronics such as laptops, mobile phones, and earbuds. It also includes industrial and commercial electronic equipment used in logistics, manufacturing, and healthcare.
Many people associate e-waste only with large consumer electronics, but the category is much broader. Common examples include:
- Household appliances (microwaves, toasters, vacuum cleaners)
- Consumer electronics (televisions, cameras, tablets)
- IT and telecommunications equipment (servers, routers, printers)
- Batteries and battery-powered devices
- Medical and monitoring equipment with electronic components
- Single-use industrial devices, including electronic temperature dataloggers
The defining characteristic is the presence of electronic components. Even small devices with a tiny circuit board or lithium battery qualify as e-waste when discarded. This is why single-use monitoring devices used in cold chain logistics fall squarely into this category.
Why are single-use dataloggers considered e-waste?
Single-use electronic dataloggers are considered e-waste because they contain plastic casings, electronic circuitry, and lithium batteries. These components cannot be disposed of through regular household or commercial waste streams. After a single shipment, the entire device is discarded, making it a significant and largely overlooked source of electronic waste in global supply chains.
The scale of this problem is substantial. An estimated 80 million single-use plastic dataloggers are discarded every year across industries like fresh produce, pharmaceuticals, floriculture, and chemicals. Each device contains a lithium battery, which requires specialist handling and cannot be recycled through standard channels. The plastic housing adds further waste that typically ends up incinerated or in landfill.
Reusable electronic dataloggers are a partial improvement. Because they make multiple trips before being retired, they reduce the per-shipment waste burden. However, they still contain plastic and electronic components, and they eventually become e-waste themselves. Data retrieval from both single-use and reusable electronic loggers typically requires USB or Bluetooth connections, adding hardware dependencies and, in some cases, creating IT security concerns for businesses whose networked computers cannot accept external USB devices.
The battery design of electronic dataloggers also presents specific challenges. Standard lithium batteries used in plastic loggers degrade over time and are sensitive to storage conditions, which can affect device reliability before a shipment even begins. By contrast, Tapp’s paper-based dataloggers use a lithium-free battery design that is more stable in storage and does not carry the same disposal restrictions as lithium cells, making them a more practical and environmentally responsible option for frequent shippers.
How is e-waste disposed of and why does it matter?
E-waste must be handled through designated collection and recycling facilities rather than general waste streams. This is because electronic devices contain hazardous materials, including lead, mercury, cadmium, and lithium, that can leach into soil and groundwater if sent to landfill or cause toxic emissions if incinerated. Proper e-waste disposal involves disassembly, material separation, and specialist processing.
In practice, a significant portion of e-waste is not disposed of correctly. Devices end up in general waste, are exported to regions with less stringent processing standards, or are simply stockpiled. For small industrial devices like single-use dataloggers, the problem is compounded by the fact that recipients at the end of a cold chain shipment are rarely equipped with e-waste collection infrastructure. A warehouse receiving a pallet of fresh produce is unlikely to have a dedicated bin for electronic components.
The environmental consequences are real. Toxic materials from improperly handled electronics contaminate ecosystems and pose health risks to communities near informal processing sites. From a business perspective, the growing volume of supply chain e-waste is also attracting scrutiny from sustainability teams and procurement departments looking to reduce their Scope 3 emissions footprint.
How can cold chain operations reduce their e-waste footprint?
Cold chain operations can reduce their e-waste footprint by replacing single-use electronic dataloggers with alternatives that generate less electronic waste per shipment. The most effective approach is switching to paper-based dataloggers, which use no plastic housing, no lithium battery, and no electronic circuit board, making them recyclable through standard paper waste streams rather than specialist e-waste channels.
As the only provider of paper-based datalogger technology, Tapp has developed a monitoring label made from agricultural waste paper with a lithium-free battery. Because the battery does not contain lithium, it avoids the most problematic element of traditional electronic logger disposal. The label can be read by any NFC-enabled smartphone with a simple tap, with no app required and no USB hardware needed. Data uploads automatically to the cloud the moment the label is tapped, giving both sender and receiver access to a full temperature report without any of the infrastructure that electronic loggers demand.
Beyond switching technologies, cold chain operators can also take practical steps to reduce e-waste:
- Audit current datalogger usage to understand how many single-use devices are discarded per month and per route
- Identify routes where paper-based loggers are suitable, particularly those involving multiple handover points where USB retrieval is impractical
- Establish return or recycling processes for any reusable electronic loggers still in circulation
- Engage receiving partners to ensure that dataloggers are not simply thrown into general waste at the point of delivery
Reducing e-waste in cold chain operations does not require sacrificing monitoring quality. Paper-based loggers provide accurate temperature data across the full range of cold chain conditions, from frozen to ambient, and are suitable for road, sea, air, and rail shipments.
