Generating electricity using low-grade heat recovered from lignin-derived membranes

Envirotec Magazine

A new study explores an apparently sustainable method of efficiently converting waste heat into electricity using certain wood products, while minimising costs and environmental impact. The study apparently shows that these membranes can convert waste heat into electricity by utilising the movement of charged atoms (ions) within the material.

CO2 monitors facilitate rollout of environmentally friendly refrigeration in Australian supermarkets

Envirotec Magazine

Supermarkets all over Australia and New Zealand are benefiting from advanced carbon dioxide monitors, says measurement expert Vaisala, as new natural refrigeration systems are installed to assist in the fight against climate change. However, HCFCs are very powerful greenhouse gases so Hydrofluorocarbons (HFCs) became more popular.

Li-ion battery risks reduced by VOC sensors

Envirotec Magazine

The safe utilisation of Li-ion batteries is a key concern for the developers of equipment such as electric vehicles, e-bikes, mobile phones and laptops. Conveniently, EMC can be detected by ION Science’s PID, so the developers of monitoring systems and equipment are able to design technologies that utilise ION’s MiniPID sensors.

Sensing evolution

Envirotec Magazine

As global awareness of the impact of poor air quality grows, so too does the demand for monitoring. The increasing prevalence of air quality monitoring in legislation, as well as with respect to corporate/social responsibility is driving the transition of air quality monitoring from a “nice to have” to a firmer commercial proposition.

Measurement of persistent organic pollutants: Recent progress profiled

Envirotec Magazine

By Gauthier Eppe Persistent organic pollutants (POPs) are toxic chemicals that pose a significant threat to human health and the environment. Current methods of analyzing POPs The gold standard method for POPs analysis is gas chromatography coupled with sector high-resolution mass spectrometry (GC-HRMS) in selected ion monitoring mode.
