Sustainability

Sustainability without compromise.

For Tharos, environmental responsibility is not a claim added at the end of product development. It begins much earlier — with ingredients, agriculture, manufacturing and the decisions made throughout the supply chain.

Start upstream Every product has a footprint.

The useful question is what we can do about it. Measure what matters. Choose responsible partners. Improve where the evidence shows improvement is possible.

Practical sustainability

Environmental impact begins before a product reaches us.

The crops used to produce an ingredient have already been grown. Energy has already been consumed. Raw materials have already moved through a supply chain.

That is why Tharos looks upstream — at sourcing, processing and manufacturing as well as packaging and distribution.

Our approach Make environmental responsibility part of how the product is built — not simply part of how it is marketed.

01 Agriculture How ingredients are grown

Farming practices and agricultural inputs shape the environmental footprint before manufacturing begins.

02 Sourcing Where materials come from

Traceability and responsible procurement are part of building a more resilient supply chain.

03 Manufacturing How products are made

Energy, emissions, water and waste all matter in an industrial manufacturing process.

04 Packaging How products are contained

Formats and materials need to balance product protection, practical use and environmental impact.

05 Distribution How products reach customers

Warehousing, shipment size and transport choices all form part of the wider footprint.

The principle Sustainability should be measurable enough to challenge.

Barley used as the agricultural starting point for malt

It starts with barley

Sustainability begins in the field.

Long before a finished Tharos product reaches an animal, decisions have already been made about agriculture, sourcing and the raw materials entering its supply chain.

Upstream responsibility

You cannot separate a product from where its ingredients begin.

Barley is an agricultural crop before it is a nutritional ingredient. Its environmental story therefore begins with farming, land, inputs and the agricultural supply chain — not at the factory door.

For Tharos, responsible sourcing means looking beyond a specification sheet. Traceability, supplier standards and the environmental performance of the wider supply chain all matter.

01 Agriculture Start at the source

The environmental impact of an ingredient begins during agricultural production, before processing or manufacture.

02 Traceability Know the supply chain

Better visibility of raw-material sourcing makes it possible to ask better questions about standards, provenance and impact.

03 Partnership Choose suppliers carefully

The environmental performance of key manufacturing and ingredient partners becomes part of the footprint of the products Tharos develops.

From barley to malt

The supply chain is part of the product.

The malt technology used within Tharos products depends on specialist agricultural and manufacturing expertise. That makes the standards and environmental performance of our supply partners an important part of our own approach to sustainability.

Working with established malt specialists allows the agricultural starting material, malting process and manufacturing environment to be considered as one connected supply chain rather than as isolated steps.

The principle The responsibility attached to an ingredient does not disappear when ownership of that ingredient changes hands.

Growing the crop is only the beginning.

The next stage is equally important: what happens when agricultural raw material enters an industrial process. Energy, carbon, waste and manufacturing efficiency all become part of the picture.

Manufacturing matters

Sustainability has to survive industrial scale.

Malting and ingredient production require substantial amounts of energy. That makes manufacturing performance one of the most important environmental considerations within our supply chain. For Tharos, choosing the right manufacturing partner matters.

Manufacturing

Environmental performance at manufacturing scale.

Tharos works with Muntons, the British malt and malted ingredients specialist whose environmental programme spans agriculture, energy generation, manufacturing, waste and supply-chain carbon.

Measured progress Better than a sustainability promise: numbers that can be checked.

56% Lower Scope 1 & 2 emissions

Total energy-related Scope 1 and 2 emissions across Muntons' UK sites were 56% lower in 2024 than the 2010 baseline.

49.4% Renewable energy

Almost half of operational energy consumption reported in 2024 came from renewable sources.

99.97% Solid waste diverted from landfill

Muntons reported that 99.97% of solid waste was diverted from landfill during 2024.

100% Agricultural sourcing standard

Agricultural products were reported as sourced to third-party environmental or social standards, including Red Tractor / SAI Silver.

Decarbonising production

Energy is one of the biggest manufacturing questions.

Malting is energy intensive, particularly because heat is required during processing. Muntons has invested in renewable-energy infrastructure at its UK sites, including biomass energy centres alongside anaerobic digestion and solar generation.

Its original target was to reduce Scope 1 and 2 emissions by 45% against a 2010 baseline by 2025. That target was reached early, in 2022.

01 Biomass energy

02 Anaerobic digestion & solar

03 Continuous energy-efficiency investment

Carbon clarity

Measurement matters more than green language.

Sustainability claims become much more useful when the underlying performance is measured, reported and capable of external scrutiny.

Muntons publishes environmental KPIs covering energy, emissions, waste, sourcing and other areas. Its carbon data is externally validated, and its environmental and energy-management systems are independently certified.

Independent recognition

King's Award for Enterprise in Sustainable Development · 2024

Muntons received the King's Award for Enterprise in Sustainable Development in recognition of work to reduce environmental impact across both its own operations and the wider agricultural supply chain.

Responsibility in practice

Sustainability is not a destination. It is a series of decisions.

Agricultural sourcing and manufacturing account for important parts of a product's environmental story, but responsibility does not stop there. Packaging, logistics and the way products are developed all create further decisions to make.

Animals and the environment in which nutritional products are ultimately used

Why it matters

Environmental responsibility should remain connected to the real world.

The purpose of reducing environmental impact is not to produce better sustainability language. It is to make better decisions about how useful products are sourced, made, packaged and delivered.

Beyond manufacturing

Responsibility continues after the factory.

There is rarely one perfect environmental choice. Packaging must still protect a product. Distribution must still move it efficiently. Product formats must still work for the people and animals using them. The task is to improve those decisions without losing sight of what the product needs to do.

01 Packaging Protect what matters

Packaging choices have to balance material use with product integrity, shelf life, handling and the practical requirements of everyday use.

02 Distribution Move products intelligently

Shipment size, warehousing, fulfilment and transport routes all influence the wider footprint associated with delivering finished products.

03 Development Keep improving the decisions

New products and supply-chain changes create opportunities to reassess materials, partners, formats and processes rather than assuming previous choices must remain permanent.

Progress rather than perfection

We would rather report progress than pretend the footprint is zero.

Every physical product has an environmental cost. Crops require land and inputs. Manufacturing requires energy. Packaging uses materials. Distribution requires transport.

That makes sustainability an ongoing optimisation problem, not a badge that can simply be awarded to a finished product. Our preference is for measurable improvement, responsible partners and claims that can withstand scrutiny.

Our position We would rather show where progress has been made — and where more work remains — than make perfect-sounding promises that the evidence cannot support.

Tharos Better products should be built with better questions.

Our approach to sustainability follows the same principle as our approach to science: understand the system, measure where possible, challenge assumptions and keep improving.
