How Does Recycling Take Place at Hiriya?
For the last few years, Hiriya has run a project to recycle mixed household waste, and a unique factory has been constructed, using innovative technology. The factory, the brainchild of the Israeli Arrow Ecology company, is an Israeli "blue and white" patent, and has become a source of international interest in the advanced waste treatment sector.
How do we do it?
In the first stage, a separation is carried out using water. The heavy waste sinks, while the light waste floats on the surface. A mechanical separation is then carried out, wherein the organic material floating on the surface is moved into anaerobic fermentation tanks, while materials that do not decompose, such as iron, aluminum, glass, plastic, and nylon, are sent to other recycling centers.
The organic components of the waste undergo fermentation processes, and are turned into biogas, from which eco-friendly electricity is produced.
The non-organic material – iron, stone, metal, and plastic – is sent to recycling factories in Israel and abroad.
The outcome: electricity, clean irrigation and washing water, and sludge, which is used as an agricultural fertilizer.
