This is especially applicable in the pilgrimage season in the city of Makkah, which is a major challenge since the amount of waste was estimated at about 750 thousand tons through Arabic Year 1435 H(2015), and is growing at a rate of 3%–5% annually. According to statistics, the value of waste in Saudi Arabia ranges between 8 and 9 billion EUR. The Plasma-Treatment Project(PTP) encompasses the direct plasma treatment of all types of waste(from source and landfill), as well as an environmental vision and economic evaluation of the use of the gas produced for fuel and electricity production in KSA, especially in the pilgrimage season in the holy city Makkah. The electrical power required for the plasmatreatment process is estimated at 5000 kW(2000 kW used for the operation of the system and 3000 kW sold), taking into account the fact that:(1) the processing capacity of solid waste is 100 tons per day(2) and the sale of electricity amounts to 23.8 MW at 0.18 EUR per kWh.(3) The profit from the sale of electricity per year is estimated at 3.27 million EUR and the estimated profit of solid-waste treatment amounts to 6 million EUR per year and(4) the gross profit per ton of solid waste totals 8 million EUR per year. The present article introduces the first stage of the PTP, in Makkah in the pilgrimage season, which consists of five stages:(1) study and treatment of waste streams,(2) slaughterhouse waste treatment,(3) treatment of refuse-derived fuel,(4)treatment of car tires and(5) treatment of slag(the fifth stage associated with each stage from the four previous stages).展开更多
