The recycled port

The STABCON project developed a cost-effective solution for treating polluted sediments in ports, using the stabilisation and solidification method. The method involves mixing contaminated sediments with products that bind them to create a solid material containing hazardous substances, reducing environmental harm and costs.

Filtering kitchen wastewater for plants

Researchers in India have found that various kitchen waste water filtration systems can produce clean water suitable for agricultural or horticultural use. Ceramic microfiltration membrane systems with physicochemical treatments such as biotreatment and adsorption showed promising results, removing up to 98% of BOD and 99% of COD.

Elderly drivers' ability to detect hazards doesn't degrade with age according to Ben-Gurion U.

A new study from Ben-Gurion University found that older drivers are more sensitive to potential hazards and focus on risky situations. The research showed that experienced and older-experienced drivers were equally proficient at hazard detection, whereas young-inexperienced drivers struggled with detecting hazardous events.

Measuring the stability of organic waste

Researchers developed a method to measure the stability of organic waste using respiration indices, which can predict biodegradable content and facilitate efficient treatment facility design. The study applies this methodology to various types of organic wastes, including food and garden waste, municipal solid waste, and sludge.

A Venus flytrap for nuclear waste

Researchers at Northwestern University have developed a new material that permanently traps only the desired radioactive ion, cesium, from a sodium-heavy solution. The synthetic material, made from layers of a gallium, sulfur and antimony compound, sequesters 100% of the cesium ions while ignoring all the sodium ions.

Protecting the future: How plant stem cells guard against genetic damage

Research by Nick Fulcher and Robert Sablowski found that plant stem cells are sensitive to DNA damage and can detect defects, triggering cell death to prevent them from being passed on. This mechanism helps protect plants against genetic damage caused by environmental stresses such as drought, high salinity, and hazardous chemicals.

Using waste to recover waste uranium

Scientists have recovered uranium from polluted waters using bacteria and inositol phosphate, a cheap waste material. The process is economically viable, especially as the world price of uranium is likely to increase, offering an environmental protection benefit.

Bringing harmony to electronic waste disposal

The global e-waste problem requires harmonization of disposal and recycling standards across national borders to effectively address the issue. The use of outdated electronic devices poses significant risks to human health and the environment, with 20-50 million tonnes of e-waste generated annually.

New use for human hair

A recent study found that adding human hair waste cubes to commercial growth medium can increase plant yields relative to untreated controls. However, results showed lower yields compared to inorganic fertilizers, suggesting hair waste should not be used as a single source for fast-growing crops like lettuce.

Strange travels

Research focuses on transport phenomena in heterogeneous media, exploring anomalous transport and its role in hydrogeology. The study highlights the importance of concentration tails in assessing radioactive waste disposal reliability.
