Brazilian perfume and cosmetics glass manufacturer Wheaton plans to use biomethane as an energy source for its glass manufacturing processes.

The group will invest in the renewable energy source to replace part of the natural gas used in its production process.

The sale of biomethane to Wheaton will be made possible by ZEG, a company specialised in the production of renewable energy.

The replacement of the fossil fuel in Wheaton's glass production will save approximately 7,000 tons of CO² emissions a year - equivalent to more than 50,000 trees planted in a period of 20 years” .

The 'GasBio renewable product that will be supplied, is produced through the sustainable reuse of urban waste in a sanitary landfill located in Sapopemba, in the East Zone of São Paulo.

Biomethane is a gaseous biofuel obtained from the processing of biogas. Biogas is a renewable and sustainable energy source, as it is produced by the anaerobic digestion (decomposition by the action of bacteria) of organic materials such as agricultural waste, animal manure, domestic sewage and urban solid waste

Wheaton currently operates four continuous furnaces with a production capacity of one billion vials per year, or 370 tonnes of glass per day.

In all, there are 23 production lines, including IS machines, in the blow-blow and press-blow processes, and rotary presses, in the pressed process.

The partnership between Wheaton and ZEG guarantees the supply of up to 10,500 cubic meters per day of the renewable product, at a cost similar to that of natural gas distributed in São Paulo.

German glass manufacturer Wiegand-Glas announced last month it is to also produce glass bottles from biomethane after it partnered with bmp greengas.
