“…The primary energy utilization over the whole life cycle of beer production, from barley malting to filling and other processes, has recently been estimated in the range 1-1.7 GJ per hectoliter of the final product (Amienyo and Azapagic, 2016), with typical electricity demand of modern breweries on average around 25-30% of the overall energy requirements (Kubule et al, 2016).…”

The basic beer-brewing industrial practices have barely changed over time. While well proven and stable, they have been refractory to substantial innovation. Technologies harnessing hydrodynamic cavitation have emerged since the 1990s' in different technical fields including the processing of liquid foods, bringing in advantages such as acceleration of extraction processes, disinfection and energy efficiency. Nevertheless, so far beer-brewing processes were not investigated. The impacts of controlled hydrodynamic cavitation, managed by means of a dedicated unit on a real microbrewery scale (230 L), on the beer-brewing processes is the subject of this paper. The physico-chemical features of the obtained products, analyzed by means of professional instruments, were compared with both literature data and data from the outcomes of a traditional equipment. Traditional processes such as dry milling of malts and wort boiling becoming entirely unnecessary, dramatic reduction of saccharification temperature, acceleration and increase of starch extraction efficiency, relevant energy saving, while retaining safety, reliability, scalability, virtually universal application to any brewing recipe, beer quality, were the most relevant experimental results. The impacts of these findings are potentially far reaching, beer being the worldwide most widely consumed alcoholic beverage, therefore highly relevant to health, environment, the economy and even to local identities.

“…More in detail, such energy demand includes 8-16 kWh of electricity and 150-180 MJ thermal (fuel) energy per hectoliter of beer produced (Olajire, 2012;Sturm et al, 2013), with energy costs amounting up to 8-9% of breweries' overall costs (Kubule et al, 2016;Sturm et al, 2013).…”

“…Cai et al [10] note the difficulties for developing energy efficiency benchmark in the mechanical manufacturing industry. Kubule et al [11] note the limitations regarding data on specific energy consumption in Latvia's industrial companies. Andersson et al [12] emphasize that energy consumption for the main, as well as, support processes may vary significantly even within the limits of a single industry.…”

This study provides an analysis to identify the comparative sustainability of the subsectors of the manufacturing industry in Latvia. Authors assess the availability of national statistics data for the development of absolute and specific indicators, which are further used for sustainability evaluation by multi-criteria analysis, specifically the TOPSIS method. Overall eight separate indicators were used for the description of three sustainability pillars. The results provide the distribution of manufacturing sub-sectors according to their comparative sustainability, and thus the rubber and non-mineral metal manufacturing sectors and wood and wood products manufacturing are evaluated as having the lowest comparative sustainability and most appropriate for further investigation regarding the development of sector-specific energy efficiency benchmark.

“…The economic sustainability of craft microbreweries has been in turn constrained by high capital costs (equipment, devices and facilities), as well as by operating costs such as deriving from taxation and energy consumption, the latter accounting for approximately 10% of the overall 6 operative costs on the average of the beer-brewing sector and substantially higher for craft microbreweries (Kubule et al, 2016;Sturm et al, 2013). All the above, despite a growing share of consumers show their willingness to pay more for the best craft beers (Mascia et al, 2016).…”

Certain typical old wheat varieties grown in the Mediterranean countries and elsewhere are renowned for their nutritional value due to higher concentration of polyphenols, especially flavonoids, as well as of important minerals, than modern varieties. However, the respective economical sustainability is constrained by reduced yield, increasing costs and stagnating or decreasing market prices. Moreover, under certain conditions, connected with the respective scale and local market volume, low-input, organically grown cereals can lead to lower environmental footprint. Brewing with a portion of such old grains can effectively boost their spreading, conditioned on its ability to supply a significant additional net income to farmers. Beer has become the worldwide most consumed alcoholic beverage and, although its market is dominated by few global players and standardized products, craft breweries have quickly spread out in most countries. Nevertheless, a scale issue has arisen about the economic sustainability of microbreweries, mainly due to high initial capital investment, energy costs, scale, and sometimes taxation. It is shown how breakthrough, cheaper, more efficient and profitable microbreweries can help solving the sustainability issues affecting old wheat varieties, thus boosting the respective spreading, lowering the environmental footprint of the cereal sector and contributing to improve the public health.
