Laminated materials have many technical advantages, but they present a significant problem when it comes to recycling due to the differences in melting points between the polymeric materials that make them up, thus restraining them from being reprocessed by extrusion. The traditional methods used for delamination are based on selective dissolution,

This technology for conversion of plastic waste into carbon nanotubes has the potential to increase the profit margin in chemical recycling of plastics. Carbon nanotubes are a high-performance additives that were found to significantly improve properties of various materials. For instance, they can be used to manufacture light weight and mechanical

The invention is an engine that converts low-grade thermal energy into mechanical work. The innovation in the proposed solution is the possibility of using low-quality heat from renewable energy sources or waste heat in a previously unused manner. A significant advantage of the proposed solution is that this engine does not require electricity for

Bread is among the top 3 wasted food globally, with hundreds of tons being discarded daily. Unsold breads are returned to bakeries from retail outlets at the end of the day despite being fit for consumption, as customers prefer to purchase freshly baked over day old produce. These breads are redistributed to charitable organisations, sold as animal

Strongly corrosive acids and highly toxic cyanide-based solutions are currently the most commonly used lixiviants for extraction of silver from solid wastes through hydrometallurgy. While acids are generally able to achieve high extraction of silver, it is non-selective and leaches most of the other metals present, resulting in a complex mixture th

Ash from power plants, such as coal ash or biomass ash, causes tremendous air pollution and mostly ends up in landfills as harmful waste. A start-up company has developed the technology and process to recycle waste ashes to reduce its harm. In the case of coal ash, harmful elements including F, Se, B, Cr, As, etc are removed using proprietary proce

Recycling or refurbishing of lithium-ion batteries is crucial in tackling the challenges of climate change and air pollution. While there is the demand for batteries to have more capacity and longer life cycles, lots of time and investment are also required to dismantle and recycle batteries. Precious metal, such as Lithium, needs to be saved while

Waste management has become a critical issue as cities run out of landfill sites - the traditional method of disposing waste - as they grapple with rising waste volumes due to growing urban populations and limited land availability. A Polish company offers a waste-to-energy (WTE) solution that simplifies waste management by converting biomass and w

Lithium-ion batteries (LIBs) have been the preferred portable energy source in recent decades. The tremendous growth in the use of LIBs has resulted in a great number of spent LIBs. Disposal of these spent LIBs will cause serious environmental problems due to hazardous components such as heavy metals and electrolytes. Materials contained in the spe

In the recent years, there has been a growing demand for biotechnology-based processes for material, chemical and fuel production to minimise the environmental impacts that chemical technology based alternatives may cause, and an increasing need to reduce waste generation amidst resource and environmental concerns. A research team has developed an

This technology provides a more eco-friendly solution to convert non-biodegradable plastics into fuels and chemical feedstocks. In Singapore, about 96% of the plastics waste is incinerated, which contributes to Singapore's CO 2 emissions and aggravates global climate change. The remaining 4% is recycled only after the plastics have been cleaned and

Mixed plastic input is cut into 10-12 mm and enters an extruder where it is melted at 200-250°C and oxygen is eliminated. The melt continues to be heated up by the superheater at 350-400°C, producing oil vapor. Subsequently, the turbulent flow medium enters the heated tubular reactor (550-600°C). The blades built into the reactor anneal the partial

Currently, most of the reported meat sauce fermentation processes are based on the natural fermentation of koji under high salt conditions, which is prepared by culturing a mold (such as Aspergillus oryzae ) on a mixture of cooked soybeans and wheat flour, and the fermentation duration ranges from 3 months to 12 months. To prevent the growth of spo

This invention is related to a novel chemical process for extracting and recycling lead from lead acid battery paste and lead ores using a batch of non-acidic and non-hazardous solvents. This method is based on the complete dissolution of all lead compounds except metallic lead at ambient conditions and without using furnace or strong acids to extr

The rapid evolution of forward osmosis (FO) within the last decade has led to the commercial implementation of the technology in the power generation sector and will address the desalination markets and the re-use needs for industrial need. Unlike reverse osmosis which uses the application of high applied pressures, FO involves the energy free and

Most commodity goods are packaged using synthetic polymers (plastics) and are treated as one-time use. Hence, considerable amounts of packaging waste ends up in land fills. Efforts to replace plastic packaging with biodegradable packaging have met with limited success. For instance, current biodegradable packaging materials are either expensive or

As the consumption of lithium-ion batteries (LIBs) for the transportation and consumer electronics sectors continues to grow, so does the pile of battery waste. Lithium-ion battery waste retains value particularly in the form of metal ions in the cathode part of the device, but few standardised methods exist to extract, recover, and reuse these pre

A UK company has developed a battery that does not run out. This is by using recycled nuclear waste and it converts radiation energy into electrical energy. Because it uses nuclear waste that stays radioactive for thousands of years, it can also produce electricity for thousands of years as well. In other words, it is a battery that never runs out,
