Acidic chelating agent

Contains: 100% citric acid.
Detergent certified by ECOCERT Greenlife according to the ECOCERT “Ecodetergent” standard available on http://detergents.ecocert.com/en 100% of the total ingredients are from natural origin.

Please note that citric acid can become clumpy when exposed to air. It’s fine to use – just break up with a spoon before use.

Derived from corn sugar. Corn is harvested, fermented, acidified & crystallised. It’s a pretty long process with a load of complex filtration & crystallisation.

Helps shift limescale in hard water. Hard water contains a whole lot of mineral ions – mostly calcium & magnesium ions. citric acid works by grabbing (chelating) these ions & stopping them forming limescale.

descale the kettle: half fill kettle. boil. add 2 tsp. stand until cool.

descale the toilet: add warm water to bowl. add 2 tbsp. leave for 1 hr + flush.

for bathroom cleaning: add 1 tsp to 1l water. spray on. leave for 30 secs. wipe off.

don’t use on natural stone. test on an inconspicuous area.

Home refills include a freepost return transit box.
Choose to reuse. We wash, inspect and refill all drums & bag-in-box liners that come back to us.

Fill refill gets packed for shipping by hand by us, in our warehouse. We date stamp and sign each transit box, so you know exactly who packed it. We don’t use any plastic packaging to ship our goods.

Glass bottles
All fill refill bottles are reusable, made in the eu with 40-60% recycled tough lab-standard glass and infinitely recyclable.

Why glass?
Well, it looks cool and it helps make refill an intuitive & permanent behavioural change. When refilling, we figured it was important to be able to see the product & the level inside to reduce risk of spillage or contamination.

– glass reduces reliance on plastic
– solid construction
– good hand feel
– aesthetically pleasing
– easy to clean & sterilise at higher temperatures
– recyclable
– good for the process when recycled
– known, fairly innocuous environmental fate

We struggled with the choice because glass has a higher impact than plastic through energy costs, but the environmental fate won out alongside the other factors. when forced to make apples-to-oranges comparisons, you have to choose what you value.
Energy costs and co2 footprint will go down as the electricity mix switches more toward renewables. For example, right now 44% of the electricity mix in britain is from renewable sources and 51% of the electricity generation is from “low carbon” sources (www.mygridgb.co.uk). The carbon intensity of energy in the uk has decreased over time from 308 g\co2/kwh over all 2016 to 206 g\co2/kwh in the last 12 months. The glass industry is undergoing somewhat of a revolution in that some manufacturers are taking the leap: “most modern traditional container, fibre and float furnaces are now equipped with electrical furnace boosting, contributing 10% to 50% of the melting power.” says heat treatment supply firm Eurotherm, while indicating that yet others are transitioning to all-electric. This indicates to us that glass’ sustainability is increasing overall on the production end, while we already strongly favour the end product of glass use in principle: we don’t abide by products or processes that produce microplastics when we can avoid it.

Screen printing
Fill refill glass bottles get screen printed once to avoid adding difficult to recycle plastic labels over and over. It’s not easy to do, but we reckon it makes things look and feel a whole lot cooler. All fill refill screens designed by the wonderful Eleonora Marton.

Cardboard boxes
We designed a tough cardboard shipping box to fix fill refill bottles during transit with no need for tape, wrap or any other crap. Transit boxes are made with >60% recycled fibres, fsc certified and printed with vegetable ink.
Cardboard is precious. It’s in short supply. we make sure to re-use every piece we possibly can & make sure to take back the transit boxes that @fill_co 10 x 500ml bottles are delivered to our wholesalers in. We’ll keep re-using them until we can’t use them any longer. We send out bulk deliveries in giant re-used boxes from other places (we roller-out the name with efi ink & stencil with ‘return for refill’).
We’ll collect & re-use any fsc pallet boxes we send out over & over, until we can’t any longer.

Infill
Once any board reaches the end of its life as a box, we’ll shred & use for infill packaging & protection for online orders, pallet box deliveries or moving precious things around.
If we make more infill than we need we’ll let you know & maybe you’d like to use it too?

Pump/trigger
All Fill Refill pumps and triggers are reusable & transferable. Sadly, like most useful things, they won’t last forever. We’ve made sure to source them without metal springs so that they are much more readily recyclable when they do eventually come to end of life.

Aluminium caps
We always choose aluminium caps over plastic. They are reusable, infinitely recyclable and look much cooler.

Paper tape
We’ve always only ever used paper tape printed with vegetable ink.
