Energy Saving
Aware of the need for responsible energy consumption and with the aim of promoting energy saving, Sumarroca has implemented a set of measures that contribute to conserving the environment and to sustainable development:
– COVERING THE TANKS
To maintain the ideal temperature of the cooling jackets (between 16 and 12˚C), the stainless steel tanks in which the wine is fermented are inside the cellar. This means there is less thermal contrast with the outside temperature and the cooling mechanisms do not need to be activated as often.
We also encourage night-time harvesting because the temperature of the grapes is lower and, once in the winery, they will require less energy to reach the optimum temperatures to prevent oxidation.
– COLD CHAMBER
The winery team found a new location for cooling the yeasts from the grape gathering to avoid having to use the cold chamber. To guarantee their preservation, a room was set up in the tank area to take advantage of the cold temperatures.
– LIGHTING
Finally, to reduce electricity consumption, we replaced all conventional lighting with low-energy lighting and installed motion sensors. These actions have reduced the wattage used by at least 50%.
We also installed new windows to allow the entry of natural light.
Sumarroca works together with the suppliers of its raw materials to achieve its sustainability goals. We adopt new measures each year to reduce the impact of our activity on the environment. These are some of the actions we have taken:
- Reducing the weight of the bottles. Over the last 10 years, this has led to a 25% reduction in our carbon footprint
- Reducing the weight of cardboard boxes by 36% . They are made from 100% recycled and recyclable material
- Eliminating the use of expanded polystyrene boxes for shipping samples, replacing them with 100% recycled and recyclable cardboard
- Replacing plastic seals with paper seals and introducing a more lightweight pallet wrap made of sustainable and degradable plastic
- Returning the label backing paper to the supplier for re-use
- New sugar cane capsules and water-based inks for the Núria Claverol and Gran Reserva Brut Nature cavas
- Using ultraviolet technology to dry the screen printing ink on Núria Claverol bottles instead of using ovens that have higher CO2 emissions
- Water fountains have been installed and reusable glass bottles are provided to eliminate plastic bottles
- Selective waste collection: all the waste we generate is separated and managed correctly. We carry out awareness campaigns for our staff. We have increased the number of collection containers. Separate collection of paper/cardboard, plastic, muselets, scrap metal, electronic material, batteries, packaging with pollutant content, ink cartridges, etc.
- Recovering wine by-products (grape marc and wine lees) for biofuel. The grape stems are used for composting
- Using paper material (office paper and envelopes), promotional material, coffee cups, business cards and other products made from 100% recycled paper
- Implementing electronic invoicing to reduce transport
- Using environmentally-friendly detergents and cleaning products.
