Scientists develop method of converting waste plastic into fuel

Scientists at Purdue University in Indiana have discovered a way to turn polypropylene plastic waste into oil, which can then be turned into petrol or diesel fuel. As part of a paper published in Sustainable Chemistry and Engineering, a team led by professor Linda Wang created the oil by adding pellets of purified polypropylene waste to supercritical water, an extremely hot and highly-pressurised form of the liquid.

The small SUVs with the biggest boots in 2023

Got a tiny driveway but lots of baggage? These small SUVs offer properly big boots. With driveways, garages and streets shrinking or disappearing altogether, inner-city dwellers increasingly want the maximum amount of interior space within the smallest possible footprint. The popularity of SUVs, particularly among family buyers, has meant hatchbacks have fallen out of favour as shoppers prioritise cargo space, head room, flexible seating options and improved visibility. RELATED: What year of Toyota RAV4 is best to buy used? RELATED: What are some reliable used cars under $5000? So what happens if you need the compact footprint of a hatchback with the boot space of an SUV? Here, we’ve collated the small SUVs with the biggest boot spaces. What constitutes ‘big’, you ask?

A surprising amount of medium SUVs, particularly hybrids, go without a full-size spare wheel. These are the cars on the naughty list… A spare wheel is no longer a given when it comes to SUVs sold in Australia. Especially for the type of car that’s meant to tackle country touring, ferry families to and from work and school, and even perform some light off-road duties, medium SUVs are arguably in the most need of a proper spare wheel. Unfortunately, the reality is that specification lists for several medium SUVs – the country’s most popular buying category – omit this important feature. Particularly when it comes to hybrid SUVs, fitting in a space-saver spare wheel – let alone a full-size – is a tall order given the packaging restraints of having to fit in a high-voltage battery.

BYD Dolphin electric-car arrival pushed back, due later this year alongside Seal sedan

Chinese electric-car giant BYD’s next two models for Australia – the city-sized Dolphin and larger Seal – are due closer to the end of this year than previously forecast. The Australian arrival of the BYD Dolphin electric hatchback has been delayed to the second half of this year, ahead of the BYD Seal electric sedan due before year’s end. BYD’s Australian distributor EVDirect has advised the  Dolphin  hatch is now due to open for orders in July 2023, and commence deliveries soon after – a delay compared to the first half of 2023 timing previously announced. The Tesla Model 3-sized Seal  sedan – previously confirmed for the “second half of 2023” – is now scheduled to open for orders and begin deliveries in the fourth quarter of 2023 (October to December), pending any further delays. The latest round of delays places the opening of order books nine to 12 months behind the “late 2022” timing indicated in mid-2022, at which time deliveries were scheduled to com...
