Responsibility Environment

 

Environment

The use of energy throughout our business has been re-evaluated over the past few years (whether it be in production transportation or building stock). This has been triggered by increases in energy costs, regulation and a new awareness of opportunities for improving energy efficiency. For Marston’s improvements in energy utilisation through green technology, building design and behavioural change are intended to drive significant savings in emissions. Heightened environmental awareness, costs, regulation and advances in technology are also driving Marston’s to develop new programmes in water use and recycling.

Water management systems have been rolled out to all our managed pubs with a significant annual saving in consumption. Kitchen waste segregation and recycling is increasing year-on-year, minimising landfill tax.

Environmental data

The energy use within Marston’s direct control is significant.

Electricity and gas usage are dominant. As we move towards higher food sales, it will become increasingly difficult to decrease our absolute energy use and greenhouse gas emissions year-on-year.

Gas and electricity usage within the breweries and managed pubs is automatically monitored and this data is validated continuously. Energy use is collected by AMR, and also from manually read meters. This data is cross checked against expected consumption. Fuels used by delivery trucks and drays is recorded and validated against expected values. Other emissions are estimated and are relatively insignificant.

Managed and Franchised pubs

Energy management

Our managed pubs represent the largest contributor to the carbon footprint under our direct control. There are dedicated energy dashboards for the pubs to highlight usual trends in energy usage, and identify specific pubs with high usage

A programme of installing green technology is ongoing:

  • LED lamps;
  • Voltage optimisation;
  • Heating control – optimised heating controls/or new boilers dependent on the quality of the existing boiler and controls; and
  • Cellar cooling in the ground cellars on the managed estate

ISTA

Over the last year ISTA have captured Marston’s utility data from invoices for the multiple managed pub sites for the purpose of better energy management. Every detail of every bill was entered into the ISTA invoice processing. Clean and current electricity and gas data, per pub, was then made available for reporting and analysis by Marston’s. The energy consumption data captured by ISTA from meter readings and invoices is input to a database that is the used to provide the figures for the Carbon Reduction Commitment (CRC). This provides an integrated approach to the compilation of the CRC footprint and annual reports to ensure a high degree of accuracy in the measurement of carbon.

Energy Profile

Throughout the year research has been conducted into the energy profile of individual managed pubs. The profile of similar pubs has been compared to identify the reasons for higher levels of energy use.

The Take Control programme includes monitoring of performance, reporting usage against targets, the preparation and dissemination of operating procedures and practices to control energy use, awareness raising activities and training. There is a feedback mechanism for our pub managers and others to report issues and opportunities.

Take Control programme

Energy reduction initiatives

Catering
Throughout Marston’s portfolio of pubs food sales have steadily increased. As such the energy demand of our kitchens has also increased. To increase efficiencies and minimise costs, Marston’s have worked on the catering specification to reduce the energy consumption and increase life expectancy of catering equipment. Innovations have included highly efficient fryers that filter oil to increase oil life, and high efficiency chargrills.

Refrigeration
Traditional fluorocarbon refrigerants are ozone depleting, or have a significant global warming impact. As such Marston’s are committed to reducing the use of these HFC’s. All of Marston’s cabinet refrigerators purchased are high-energy efficiency hydrocarbon units, which are manufactured in the UK.

LED Lighting
Lighting makes up a significant proportion of the electrical consumption of a pub. In response to the challenge to minimise this energy use, Marston’s have rolled out LED lighting. Generally LED lighting consumes 80% less energy than tradition incandescent lighting. We install LED lighting in all of our new-builds and refurbishment projects.

Pitcher & Piano LED Retrofit – A Case Study
Pitcher & Piano was identified for installing LED lighting due to long lighting hours, high bulb replacement costs and high power consuming lighting. The following graph shows the saving attained in the LED rollout.

Voltage Optimisation
Voltage optimisation increases the efficiency of electrical equipment, whilst also preventing electrical surges. We have installed voltage optimisation in all of our new-builds and have retrofitted to over 40 sites. The units are more efficient and have a considerably reduced embedded carbon footprint, meaning carbon payback is reduced by 17 per cent.

A BREEAM assessment uses recognised measures of performance, which are set against established benchmarks, to evaluate a building's specification, design, construction and use. The measures used represent a broad range of categories and criteria. They include aspects related to energy and water use, the internal environment (health and well-being), pollution, transport, materials, waste, ecology and management processes. Buildings are rated and certified on a scale of ‘Pass’, ‘Good’, ‘Very Good’, ‘Excellent’ and ‘Outstanding’.

breeam

Many of our new-builds are now built to Breeam Standards; we have achieved many Breeam Very Good’s and one Breeam Excellent.

BREEAM Excellent New Build - Blaina Wharf, Newport

Blaina Wharf, Newport

Blaina Wharf has successfully achieved BREEAM excellent. BREEAM is an environmental standard for sustainable building design, construction and operation. It has become one of the most comprehensive and widely recognised measures of a building's environmental performance. This has been achieved by installing the latest energy saving technology. Photovoltaic panels have been installed to generate renewable electricity from the sun’s energy. Air Heat Source Pumps have been installed, which transfer heat from the atmosphere outside to inside the pub. The lighting is provided by LED that uses approximately 80% less energy than conventional lighting. Fresh air is used to cool beer when temperatures are low enough outside. The building has been constructed adhering to the BREEAM excellent standard, ensuring the environmental impacts of the building are minimised during its life cycle.

Taverns and leased pubs
Our tenants and lessees are responsible for the energy used in the pubs they operate. However, we aim to support their efforts in energy and carbon management by the transfer of our knowledge and experience. Through our online portal – “My Marston’s Online” - we offer information on energy saving strategies.

We are currently investigating innovative finance solutions to assist with the implementation of measures and will be offering training and support.

Energy - Breweries

Our breweries are highly committed to energy efficiency. In the last four years we have invested in energy and carbon management projects: better monitoring and control, improved refrigeration and efficient lighting.

There are also extensive energy monitoring systems at the two largest breweries at Wolverhampton and Burton.

There is a general correlation between relative change in production volume and performance – an increase in volume invariably leads to an increase in efficiencies, and corresponding reductions in tCO2/tonne product.

Energy - Transport

We have a large fleet of trunking and retail vehicles. Our fleet vehicles cover approximately 7 million the equivalent of travelling around the earth over 300 times.

We aim to reduce the fuel efficiency ratio of our fleet, and we monitor our mileage per gallon monthly to identify potential inefficiencies. We also measure miles travelled per delivery and miles travelled per barrel to ensure that our routes are optimally efficient.

In the coming year we are looking to implement a new system to monitor driver efficiencies. This will consider driver safety, but also have a fuel efficiency component.

Improvements in fuel efficiency have so far been down to the use of new vehicles, and the following initiatives:

  • All vehicles that run into the London area are Euro III compliant and meet the standards required by the London Emission Zone (LEZ)
  • We have installed satellite tracking in all our retail delivery vehicles, which has helped with more efficient planning of routes and management of the logistics operation

Water Management

We use water in our breweries both as an ingredient of beer and for cleaning barrels and brewing equipment, and in our pubs for everyday use and washing in our kitchens.

Within our managed pub and franchised portfolio we rolled out water management systems in 2014 which have driven significant improvements in efficiencies.

Water - Managed pubs

Our pubs use water in a number of ways: cooking, food preparation, drinking, cleaning and flushing. Water usage historically has not been as well metered as other utilities.

Since 2012 Marston's has sourced new technology to better manage water use in the toilets of its managed pubs including urinal management systems to control the amount of flushes depending on customer usages.

water consumption

Water - Breweries

Water consumption is a key performance indicator for site managers at all five breweries and we continually monitor our usage to identify potential reductions. Last year, our breweries use over 900,000 m3 of water a year. This is taken from both the mains supplies and from boreholes.

At Burton we currently use up to 7 barrels of water for every one barrel of product brewed and bottled. This ratio is 5 at Wolverhampton and between 2.17 to 4.37 at the other three breweries. The difference in ratios is the result of a more modern brewing process at Wolverhampton, whereas Burton uses larger numbers of small oak barrels in our more traditional process, the Burton Union System.

We also look at our water efficiency in terms of water used in proportion to effluent produced. In Burton 69% of the water brought on to site was eventually discharged as effluent to the sewer; at Wolverhampton this ratio was similar at 71%. The industry average is approximately 44% (BBPA) which our three smaller breweries are closer to. We are trying to minimise our water use at Burton by cleaning plant with recovered water from the clean rinse phase of cleaning tanks and pipes.

We work with water authorities and the Environment Agency to ensure that we meet standards for the disposal of rainwater and effluent. Last year we did not have any breaches of regulations or compliance failures.

Waste Management

Case Study: Diversion of waste from landfill

Focus upon our pubs:

At Marston’s, we understand the importance of managing our waste responsibly. Food waste, empty bottles, plastics, cardboard and cans are all part of our everyday lives, and within our industry we see this waste on a much larger scale. The UK catering industry produces 3.4 million tonnes of waste every year, and we at Marston’s generate around 64,000 tonnes (2016: 53,000 tonnes) through our breweries, pubs, restaurants and lodges. As a company, we look to avoid, reduce and reuse our waste, but where that is not possible we aim to recycle as much as we can.

Of the total 64,000 tonnes of waste produced in the 12 months to September 2017, 29,000 tonnes came from our brewing processes and 35,000 tonnes came from our managed and franchised pubs. Of this total we recycled 72% (2016: 61%); the remaining waste was sent to either energy from waste plants or landfill.

We have increased the number of sites from which waste food is collected during the year from 346 to 547 by working with our waste contractor UK Waste Solutions.

Currently 73.6% of sites with a food offer are recycling food waste (2016: 52.4%). Our food is recycled by anaerobic digestion (AD) producing biogas which is burned on-site to generate electricity. In 2017, Marston’s food waste generated enough electricity to power Wychwood Brewery for 2.4 years.

Our focus upon increasing food collections, and segregating waste better at the sites has meant that we have managed to increase our total recycling rate for the pubs and reduce in one year the amount of waste going to landfill by over 25%.

Focus upon our breweries:

Including spent grains and hops, every year Marston’s recycles close to 98% of the waste produced by its breweries.

The waste from our breweries such as the spent grains and hops are recycled as animal feed after brewing (approximately 25,000 tonnes a year!), while waste yeast and beer goes to AD; we also dispose of other waste such as glass (cullet), metals, cardboard, paper and polythene through local recycling contractors.

A centrifuge was installed in Wolverhampton brewery to reduce effluent. This concentrates waste yeast rather than disposing of it. It also improves the beer quality and reduces the environmental impact of the waste.

Case Study: Awareness campaign “Wise up to Waste”

Waste Management managed and franchised pubs In 2017, we recycled 72% of our waste from managed and franchised pubs (61%: 2016) and diverted 96% from landfill (see pie chart for breakdown). In the final period of the year, 76% of waste was recycled. The improvement over the last year has been driven by both a bin rationalisation project, which involved conducting a waste audit at every pub in the business, and staff culture change campaign. This ongoing campaign, with the tag line “Wise up to Waste”, is designed to make our staff think before they throw so more of our waste can be recycled and we can reduce our impact on the environment even further. Take a look at our educational video which highlights the importance of correct segregation and what happens to our waste when it leaves our pubs.

We achieved our 2017 glass and dry mixed recycling targets. 98% of sites are recycling glass (2016: 89%) while 97% of sites have a dry mixed recycling service for paper, cardboard, plastics, tins and cans (2016: 78%).

Targets

By the end of the 2017/18 financial year, we aim to recycle 80% of waste from our managed and franchised pubs. In addition, 80% of sites with a food offer will be recycling food waste. We are working in partnership with our waste broker, UK Waste Solutions, to develop a strategy for achieving zero waste to landfill and hope to have a target in place in the near future.

To achieve these aspirational targets we will continue to review our pubs’ bin specifications and performance to identify further opportunities for recycling. We will expand the “Wise up to Waste” campaign using recycling league tables, waste champions and online training to improve segregation of waste on site.

Rather than have a vehicle collecting used cooking oil (UCO) from each individual site we use our fleet to backhaul the oil to our distribution centres throughout the UK where it is then sent for recycling by a specialist contractor into bio-diesel. Backhauling has the advantage of maximising profits, increasing storage space at pubs and reducing CO2 emissions from transport. In 2016, we recycled 787 tonnes of UCO. Given the benefits of backhauling to the business, we hope to trial backhauling of other waste streams such as cardboard and plastic wrap later this year.

Breweries

The waste from our breweries such as the malt, hops and waste beer is recycled as animal feed after brewing; we also dispose of other waste such as glass (cullet), metals, cardboard, paper and polythene through recycling contractors.

A centrifuge was installed in Wolverhampton brewery to reduce effluent. This concentrates waste yeast rather than disposing of it. It also improves the beer quality and reduces the environmental impact of the waste.
