How about incinerating Earth’s trash with the sun?

In the modern era, as our planet struggles with its trash problem, an intriguing proposal has emerged in scientific and academic circles: could we send Earth’s trash directly to the sun?

At first glance, this may seem like a great endgame for garbage disposal, harnessing the immense heat of our star to eradicate trash.

However, a closer look reveals a number of problems that make this solution impractical.

The sun: the ultimate rubbish incinerator?

With a surface temperature of 5,500°C, the sun has the potential to break down every known substance.

In theory, waste sent to the sun would instantly vaporise, leaving no residue behind.

It sounds like an attractive prospect – a cosmic solution to Earth’s problems.

However, there are some significant challenges:

Astronomical cost

Space launches are notoriously expensive.

As of 2023, the cost of sending a 1kg payload into space is in the thousands of dollars.

Considering the massive amount of waste that humans produce every day, the economic impact of such an endeavour would be staggering.

Complex orbital planning

Contrary to popular belief, sending waste to the sun is not as simple as pointing a rocket upwards.

The motion of the Earth and the dynamics of its orbit around the sun mean that a huge amount of energy is required to offset the speed of the Earth itself to ensure that the payload lands on the sun.

This energy expenditure could be better utilised in a ground-based solution.

Risk of catastrophic failure

Space missions inherently involve some degree of risk.

Failed launches or on-orbit errors can result in space debris, and in the worst case scenario, the debris can re-enter the Earth’s atmosphere and cause massive environmental damage.

Waste of resources

Many discarded objects contain materials that have the potential to be recycled.

Sending rubbish to the sun permanently deprives us of the opportunity to reuse these valuable resources.

Environmental footprint

The environmental impact of frequent rocket launches would be significant.

The emissions of rocket propellant and the carbon footprint associated with the manufacturing and launch process could potentially exacerbate the very environmental problems we are trying to mitigate.

Realistic perspective

While the concept of harnessing the sun for waste disposal may capture the imagination, it is a distant prospect due to current technological, economic, and environmental constraints.

Instead, investing in sustainable waste management practices here on Earth may be a more realistic approach.

This includes improving recycling processes, promoting waste reduction, and exploring technological innovations in waste disposal.

The solutions to the problems we face as stewards of the planet may be closer than we think.
