The Ministry for Ecological Transition reported that Spain collected just 41.3 percent of single-use plastic beverage bottles in 2023, missing its 70 percent target and opening the door to a national deposit-return system as early as 2027. European Environment Agency profiles on municipal waste underline the country’s reliance on extended producer responsibility schemes that now cover both household and industrial packaging following updates in 2025. Law 7/2022 on waste and contaminated soil has required separate collection of plastics and other materials from households since early 2024, forming part of European Union directives that seek to halve single-use plastic packaging weight by the end of this year.
Market.us data places the global soda maker sector at 1.053 billion dollars in 2025, forecasting expansion to 1.94 billion dollars by 2035 with a 6.3 percent compound annual growth rate driven by urban households seeking sustainable alternatives. Separate assessments indicate the European sparkling water market stood at 14.73 billion dollars in 2025 and is set to reach 16.33 billion dollars this year as regulations on single-use plastics gain force. These trends coincide with broader consumer shifts toward reusable systems that reduce reliance on bottled imports across compact city environments.
Systems designed and manufactured in Spain for Spanish consumers minimise transportation distances, delivering cleaner logistics, faster distribution and lower overall costs than products shipped from abroad. Congas offers one such locally developed solution through CO2 cylinder refills and stainless steel machines that let households produce sparkling water on demand without long-term commitments beyond optional service plans. The domestic focus supports national environmental priorities by shortening supply chains within Spain while addressing everyday demand for carbonated drinks.
Congas’s Soda Club subscription can cut expenses by up to 40 percent with cylinder pricing from 16.5 euros, while starter packs begin around 200 euros and include automatic alerts to prevent shortages. The process involves delivery of full cylinders, home use in the machine and scheduled pickup of empties, removing the need for store visits or manual returns. This setup directly eliminates plastic bottle waste that would otherwise accumulate from repeated purchases of commercial sparkling water.
Publications such as Healthline have stated that plain carbonated water provides a calorie-free alternative to sugary sodas and may improve swallowing ability along with feelings of fullness, though acidic flavourings can still affect dental enamel over time. Reviews of available studies confirm that the absence of added sugars makes sparkling water a preferable choice for those aiming to reduce sugar intake without sacrificing refreshment. Such health considerations have grown more prominent as Spanish consumers respond to both regulatory and personal wellness pressures.
Ecoembes figures indicate more than 2.2 million tonnes of packaging were recycled in Spain during 2025 from a total of 3.54 million tonnes placed on the market, yet collection shortfalls for plastics continue to drive policy adjustments. Local manufacturing of carbonation equipment further trims the carbon footprint tied to long-distance freight, aligning with circular economy objectives embedded in recent decrees. Analysts anticipate sustained sector growth as tighter targets for waste reduction extend through 2030 and beyond.
