Waste Treatment Plant in Querétaro (México)

Bianna Recyling, a multi-national company specialising in the manufacture of waste treatment equipment and plant construction, is about to complete the construction of a facility in Querétaro. The plant was built in strategic collaboration with Mexican company GTA Ambiental, Bianna Recycling’s exclusive agent in Mexico. It is the first facility in Mexico to feature a ballistic separation line, which is a key technology for material recovery and commonly implemented in the European waste treatment model. The plant is located in the municipality of Monpani and will serve the population of Santiago de Querétaro. It will manage around 400,000 tonnes of waste per annum.

The project entrusted to Bianna Recycling encompassed engineering, manufacture, assembly, commissioning, staff training in operating and maintenance, and plant maintenance. The facility will serve the population of Santiago de Querétaro and will manage around 400,000 tonnes of waste per annum. “It is the first facility in Mexico to implement the European Mechanical Treatment (MT) model for solid waste management. For the first time in this country, a plant is equipped with ballistic separators to separate a number of waste streams” points out Francesc Rosell, Deputy Managing Director at Bianna Recycling.

This is a pioneering separation line in Mexico and a concept crucial to the recovery of materials and facilitating the work of sorting operators. The facility has a second line that produces RDF with a high calorific value from MSW.

Cost effectiveness in the spotlight

The cost effectiveness of the facility was a key priority and strongly influenced Bianna Recycling’s design of the engineering processes, bearing in mind the specific nature of the waste, amongst other parameters. The facility is made up of two lines with a total capacity of 75t/h, which carry out separation of recoverable by-products (with a high recovery rate) and the organic fraction. “The reject fraction is specially treated in an RDF production line, meaning that the fraction sent to landfill is extremely small”.

The plant is expected to recover between 8% and 10% of the MSW in by-products of value, while RDF could account for the recovery of 20-30% of the input waste. When it goes into operation, the Bianna Recycling facility will have a 90% uptime rate, enabling it achieve a return on investment within the envisaged deadlines. “Thanks to the robustness, design and sizing of the equipment, the plant will have very low operating costs (OPEX)”, explains Francesc Rosell, who has monitored the project very closely.

Project presentation

The project was presented last March and the event was attended by the president of the municipality of Querétaro, Mr Marcos Aguilar Vega, who provided a description of some of the most relevant aspects of the municipal solid waste treatment and separation plant, considered to be the largest and most modern in Latin America. As was pointed out in a number of media sources, this plants is “one of the most important infrastructures built in the city of Querétaro in recent years and marks a before and after for the city in terms of the environment”. The new plant is located in the Paseo Querétaro, previously called the Carretera Monpaní. It will enable 78% of the MSW to be availed of. The facility will employ over 200 people, working in two separation shifts and a third preventive maintenance and equipment cleaning shift. The building of the plant required 300 tonnes of steel, 1,400 rollers, six kilometres of cables, and one kilometre of conveyor belts, all of which reinforces the fact that it is Latin America’s largest treatment plant.
