Scientists Developed New Long Lasting And DEET Free Insect Repellent Against Malaria-Carrying Parasites

The World Health Organization has long been recommending insecticide treated nets and spraying as main steps in controlling the spread of malaria. With growing concerns from consumers regarding repellents made with synthetic ingredients, DEET free repellent in Australia, United States, UK, China, Africa, and other parts of the world is becoming a more favourable choice.

Going DEET-free

N,N-diethyl-meta-toluamide or DEET has been a concern because it puts humans at risk when used. Consumers have reported skin irritation, high absorption, odour, and oily feel upon using repellents with DEET. People get even more concerned when using these in homes with children, pregnant women, elderly, and ill individuals.

Why is it taking so long?

Looking for an effective DEET free repellent in Australia, for example, can be proven a challenge because finding new compounds that can work just was well without the harms is a difficult task. This makes the process time consuming and expensive. Establishing the safety of the new chemicals is also a lengthy process as it involves different set ups and variables to test the limit of the repellents.

Additionally, there has been increasing reports of malaria infections in Africa where patients were exposed outdoors. This means that indoor protection isn’t doing enough anymore, and scientists need to find a way to mitigate the problem and protect people when they are out.

How it works

Many repellents are made with compounds mixed with oils. However, the problem is that they evaporate quickly, and needs frequent reapplication.

Scientists wanted to create an alternative that could make the repellent last longer. This was achieved by using a mixture of substances that would take longer time to evaporate, thus increasing the period of time it stays on the skin. The new formula was able to last up to six hours on the skin, and has also shown to have killed the mosquitoes that came into contact with it.


The study, however, although successful in repelling and killing malaria-carrying mosquitos, does not account for Plasmodium falciparum, a malaria-spreading parasite that has developed resistance against existing methods. The scientists believe that further research needs to be done to address said problem, but the new formulation is a step towards better protection nonetheless.


Reverse Vending Machines To Encourage Plastic Bottle Recycling

Snacks, chocolate bars, beverages or cigarettes are available on demand through vending machines after a consumer inserts money, a credit card or a specialized card on the slot provided. The machines in public areas and recreational centres are delivered through vending machine delivery service that uses a vehicle specially designed for the purpose.

Recently, the traditional vending machine has been reconfigured for less common products or merchandise. Iceland will be the first UK supermarket to install an in-store reverse vending machine. The idea behind the reverse vending machine is to support the government’s initiative of introducing a deposit return in England.

Trial for the reverse vending machine will be undertaken by a frozen food specialist in Fulham, London for 6 months. The aim is to fully understand the perceptions and appetite of consumers for the technology. Iceland wants to scrap plastic packaging and palm oil from its own label products.

The reverse vending machine will provide consumers with an incentive for recycling. Money or vouchers will be provided when empty containers are returned. Iceland’s reverse vending machine will accept any Iceland plastic beverage bottle. The consumer will be paid with a £0.10 voucher that can be used in the store where the bottle was recycled.

According to Iceland’s managing director Richard Walker, they have received encouraging public support after their announcement to eradicate plastic packaging. They are the first to take a decisive action by bringing the reverse vending machine to stores after the government announced its support for the deposit return scheme. The company has taken the proper steps following consultations with suppliers and understanding customer behaviour and response.

It is absolutely important to act now in order to reduce if not eliminate plastic pollution that is killing dolphins, choking turtles and degrading the environment. The trial scheme of Iceland has received support from businesses that want a better state for the environment.

A high quality logistics provider will check the working order of a machine before vending machine delivery service is called to perform the task. Vending machines are usually specialized with new technologies and digital displays. They need a logistics provider that will take all the necessary precautions during delivery.
