There are several recycling facilities in the park that deal with different types of waste:

Arrow Ecology
Part of Hiriya's waste (approximately 200 tons per day) reaches this site daily, and is recycled in the Arrow Ecology facility. The facility is considered to be one of the world's leading waste treatment facilities, and includes a unique system – an Israeli "blue and white" development – that separates organic waste from non-organic waste using water.
This Israeli patent is based on the relative density and properties of different components of waste. The garbage trucks unload the garbage into a pool of water, and the force of gravity separates heavy and light waste, materials that absorb water (paper) and materials that do not (nylon and plastic), materials that maintain their cohesion in water (iron, other metals, glass, plastic, and nylon), and so on. Most of the materials are then sent to the appropriate recycling centers. Organic material floats on the surface of the pool and undergoes hydraulic crushing before being moved to fermentation tanks. In these tanks, natural methane gas is created, which is used to produce electricity and organic manure for agriculture. A large quantity of fluids accumulates during the fermentation process, and this is then used for irrigation purposes and for washing the waste trucks.

Sorting and Recycling Facility for Construction Waste
This waste comes from building sites throughout the Dan region, and is mainly composed of concrete, other stone, and iron. At Hiriya, the waste undergoes a sorting process. Initially, the iron and wood are separated while the other elements are crushed and separated into sand and gravel, to be used for infrastructure. This unique facility can process approximately 2,000 tons of building waste per day. These end products are used as a filling substance to stabilize the slopes of Mount Hiriya as part of the rehabilitation process. |

Energy Center for Mount Hiriya's Biogas
As a result of the waste's natural decomposition process, biogas is created in the belly of the mountain. It is composed mainly of methane, carbon dioxide, and other gases. The conditions in which the waste is stored determine the quantity of gas released. In the dumping site conditions, approximately 120m³ of biogas is created per ton of waste, and over 16 million tons have accumulated in the Mount Hiriya site over the years.
Methane is one of the main components of the biogas. It is considered to be a clean energy source, and is used to create electricity. It is preferred to polluting gases used in the industry. In the Hiriya recycling park, a system to collect the biogas has been constructed, pumping approximately 1,200m³ of gas per hour from 70 wells located on the mountain.

Garden Trimmage Recycling System
Approximately 250 tons of trimmings arrive at Hiriya daily, where they undergo a sorting and cutting process. The thin branches and leaves are shredded into chips that are used to create organic fertilizer (compost), ground coverings, and even steam. The larger tree trunks are passed on to different wood shops where, in the professional hands of the artists, they are transformed into beautiful garden furniture. We call these "Hiriya Products" with pride. If you see this brandname on public benches, you'll know that it was made from recycled Hiriya products. |

"Green Basins"
The garbage that accumulates in the waste mountain produces leachate (garbage "juices"). The contaminated leachate is pumped into "green basins", a system of five pools with unique plants and aggregates that form a natural sieve to absorb microbes. |

Cardboard
Cardboard is separated from the household waste when it reaches the transfer station, and is transported to the Amnir recycling factory in Hadera, which specializes in recycling paper and cardboard.

Eureka!
Office Textile, a company in the small town of Azor, has already purchased the rights to use the biogas from Mount Hiriya. Today, they are enjoying the benefits of using cheap green energy, which is used to create electricity and steam.
