Client: Distillerie Sud Languedoc

Country: France

Start-up year: 2019

Production: 2,6 MW Steam

Fuels: Wood chips, Grape waste

During the distillation process steam is required to perform a heat exchange with the substance to be distilled, boiling the alcohol and recovering it later, thus increasing the graduation of the drink or obtaining the required alcohol products.

The implantation of biomass in a distillerie is interesting from different points of view. First, it means a decrease in the cost of steam produced. Secondly, it allows the company to use the by-product of its process, the pulp of pressed grapes, as fuel along with the wood chips, further lowering costs. As a last but not least, it reduces the environmental impact of the company, so it helps to take care of the land where its vineyards extend.

Client: SabMiller

Country: El Salvador

Start-up year: 2016

Production: 4,2 MW Steam

Industrias la Constancia (ILC) is a SAB Miller production plant located in San Salvador, El Salvador. 

SAB Miller is the second biggest beer producer in the world, now property of Anheuser-Busch InBev, the world beer production leader.

In Industrias la Constancia, AB InBev produces more than 10 drinks, including Coca Cola products, Pilsener or Suprema among others.

Due to environmental and economic factors, ILC considered the implementation of alternative energy resources. A key point when they were choosing the solution was to implement an energy generation system that allowed them to take advantage of its process by-products. Moreover, the main fuel used to feed the system apart from the production derivatives is King Grass from nearby farms.

In Industrias la Constancia, the generated steam is used mainly in 2 different ways. In a first place, it is used to keep the beer ingredients at a high enough temperature to allow an easy fermentation. In second place, it is used to disinfect different products, such as the beer or cola bottles. Through the biomass boiler providing saturated steam, BaW Energy provides an environmentally friendly solution able to fulfill those requirements.

The scope of the installation includes a biomass storage silo consisting of a semi-automatic crane, the biomass transport and feeding system to the furnace through an hydraulic pusher, the furnace and the boiler, both with water cooled walls, the ashes recollection system and the flue gases filtration and evacuation system. The pressure parts are designed and manufactured fulfilling ASME codes.

The BaW biomass plant has permitted ILC to save 72% of the steam generation costs and decreasing in 9.440 t CO2eq/year the greenhouse emissions respect the previous fuel. The payback of the project is approximately 1 year.

Client: SEDA Outspan

Country: Spain

Start-up year: 2016

Production: 10,4 MW Steam

Fuels: Spent coffee grounds, Wood chips

SEDA OUTSPAN IBERIA S.L. is a soluble coffee and substitutive product elaboration and commercialization company. They produce their own brand and for other ones.

In 2014 they had a biomass boiler and they considered to change the old one for a bigger one, due to the steam demand raise owing to the production increase. With this change they wanted to continue generating energy cleaner and being able to use all its producing waste in addition to decreasing the CO2eq emissions with this new state of the art plant.

The productive process of SEDA generates solid coffee grounds. Once the humidity of this fuel is lower than 55%, it is used as fuel for the furnace, not needing the addition of other kinds of biomass to burn.

The designed system is able to generate 16 t/h of 16 bar steam, using as fuel coffee grounds wastes generated in the producing system with a maximum of 55% humidity.

The scope of supply includes two biomass storage silos, one for the process coffee grounds and another to storage wood chips in the case that the property doesn’t have coffee grounds available. These silos can be filled directly using trucks. Using a chain conveyor and screw conveyors, the biomass is driven to a feeding silo. The scope includes too the furnace feeding system, the furnace with water-cooled grates and refractory walls (to hang the humidity of the fuel), the water- cooled boiler, an economizer to increase the facilities efficiency, an ashes collect and transport system and a smokes filtration and evacuation system. In this case, the filtration is done through a multicyclone and an electrostatic particle filter.

The implementation of the BaW biomass plant has made Seda Outspan save 45% of its energy costs* and decrease in 17.000 t CO2eq/year the greenhouse emissions respect the previous fuel. The payback of the project is approximately 3 years*.

Client: Moldosa, Molpasa

Country: República Dominicana, Panamá

Start-up year: 2016

Production: 2 x 3 MW Thermal oil

Moldeados Dominicanos S.A. and Moldeados Panameños S.A. are companies working in the paper pulp industry. The plants characteristic point is that they use only recycled raw material.

In 2015, under the environmental actuation plan, they consider an improvement of their energy supply. The objective of the change was to obtain the energy needed for the productive process in a cleaner way and with more efficiency.

The system consists in an automatic biomass combustion system, using the energy generated in the furnace to heat the thermal oil in the thermal fluid boiler of 3 MW. This oil is driven to the heat exchange batteries, where a thermal exchange heats the air used in the manufacturing process

To provide the best possible solution, BaW Energy designed a new furnace prototype for these facilities. This furnace improves the combustion of the biomass, obtaining lower pollutant gases emissions and fewer particles. In addition the facilities include an economizer  to preheat the water used in the manufacturing process.

The implementation of the BaW biomass plant has made Moldosa and Molpasa save 61% of the energy costs and reduce in 5.200 CO2eq/year the greenhouse gases compared to the previous fuel, natural gas. The payback is approximately 1.3 years.

Production: 2,6 MW Steam; 2 MW Chilled water

Fuels: Grape waste, Wood chips

Miguel Torres S.A. is a leading company in the wine industry all over the world, the most admired for second consecutive year according to Drinks International. In 2008 the brand presented a step up in the energy supply over the actuation of the environmental impact reduction, with the aim to obtain cleaner energy.

The brand decided to implement a new energy supply using biomass, that allows the use of organic matter derived from the wine production, realizing an energy recover of this waste.

The main energetic demand of the wine production is cold energy. Apart from this, it is needed steam in other industrial tasks.

BaW Energy provides them an integral solution environmentally friendly. The biomass combustion system provides the necessary heat to generate the steam needed in the absorption process to generate the required chilled water. The remaining steam is used in the plant for other industrial purposes.

The scope of the installation includes the storage silos for the used fuels, the transport and furnace alimentation system, the furnace and the boiler, both provided of water-cooled walls, the ash collecting system and the smoke filtration and evacuation system.

The incorporation of the BaW biomass plant has permitted Bodegas Miguel Torres to save 10% of electric consume (1.000 MWh/year) and a 95% of natural gas (420.000m3/year), as well as reducing in 1.300 t/year the CO2 emissions against the previous energy system.
