Green Cone still going strong after 25 years

Although a Green Cone is expected to last for at least 10 years, customers often report their Cone has lasted a lot longer than this.

The oldest Cone that we’ve heard of belongs to a lady in Scotland, who got it through her local authority, Argyll and Bute District Council, 25 years ago.

The customer’s daughter contacted us when the Cone’s lid blew off in a storm and Great Green Systems replaced it free of charge.

 She said: ‘The Cone is still going strong, a real asset in a rural area where there is no specific collection of food waste. ‘

Another Cone going strong, and coping with extreme heat, is one that was taken to Spain by its owner, Angela, nearly 20 years ago when she bought an old Spanish farmhouse.   

Angela knew the Cone worked well at home in England so it would be an even greater asset in Spain, with heat, foxes and rodents to contend with. The family took their Cone over to Spain in their car.

‘We love our Cone and it is really, really useful,’ says Angela.  ‘I must say that we have been surprised and delighted that the actual Cone has lasted brilliantly all these years. We wouldn’t want to be without it.’

For several years the family made annual trips to their Spanish house, spending working holidays getting the house and garden ready for their eventual move.

On one visit a big family birthday was celebrated with 10 guests staying for a full week. The Cone’s underground basket (which is where food waste lands) was full after the week, but when the family returned months later they were delighted to find that the basket’s contents had almost completely vanished.

A long reign in Spain – Angela’s Green Cone outside her Spanish farmhouse.

The family relocated to Spain a few years ago and over the years Angela has seen big changes there in attitudes to recycling food waste.

She says: ‘Things have become easier over the past few years as Spain has started to install special organic recycling bins, which have a swing top and drop waste into an underground receptacle that is then cleared very regularly by the council.  

A good ecological cycle

‘So, from nothing less than 20 years ago, we have multiple ways of safe and hygienic organic waste disposal, the most convenient of which is our Cone.

‘To be honest, it is as much of a pleasure to take the bin out to the Cone as it is to go out and pick veggies for supper because it is useful to process things ourselves and know that we are using a good ecological cycle for production and waste.’ 

The couple grow a lot of their own produce and have had to contend with many challenges posed by the climate and mountainous geography. Their Cone has been moved four times, with placement being determined by where there is sufficient depth to site the basket, which needs to be embedded in soil.

‘When there is torrential rain and it floods over the terrace behind our land it can remove soil down to the bedrock, it was quite a shock the first time we saw this and realised just how little soil covering there is in some places,’ Angela says.

‘As a consequence, we have built raised beds for some of our produce and will be looking to make deeper beds for some others as time goes by.’

A 5000-litre tank for rainwater has been an essential investment.

Angela says the Spanish are becoming much more interested in tending gardens.

 ‘People have been quite interested in our approach (raised beds, adding marigolds for insect control and so on). Possibly they will become more interested in composting as well since many areas have banned burning of waste, partly as a fire hazard and partly air pollution, so things are changing gradually.’

How to get the most from your Green Cone

Get the basics right and life with a Cone at home is simple and convenient.

The Green Cone’s basic needs are:

  • A sunny spot
  • Well-draining soil (not clay or chalk)
  • Accelerator powder to boost digestion

Where shall I put my Green Cone?

All the instructions you need are included in the instruction manual, but here are a few pointers worth remembering.

When thinking about where to place the Cone, as well as finding a sunny spot it’s a good idea to think about how easy it will be to get to in winter months to empty your kitchen caddy.   

More than 90% of the waste added to the Cone will be turned into water, which must be able to drain freely away for the unit to work properly.

How do I know if I have good drainage?

If you’re not sure whether your soil has good drainage or not, you can check by doing the following: dig the hole required for the Cone (about 70cm wide by 54cm deep) and pour a bucket of water into it. If the water remains for more than 15 minutes you have poor drainage and will need to enlarge the hole to 90cm wide by 70cm deep. Provide extra drainage by mixing soil from the hole with gravel, stones, or small pieces of broken bricks and pots and placing some of this mix in the base of the hole so that when the assembled Green Cone is added the basket sits 3cm below ground level. Then use the gravel/soil mix to backfill gaps around the Cone until the bottom rim of the green outer cone is fully covered.

How do I look after my Green Cone?

Basic maintenance involves ensuring that the Cone’s green rim always remains below ground level.

In the first few weeks after installation check that soil has not settled and left the green rim exposed. This could also happen after heavy rain. If this is the case, make sure to add additional soil and compact it around the Cone to keep the rim securely underground.

How much waste is too much for the Green Cone?

Remember that food waste should only ever be in the underground basket: never allow waste to build up so that it is above ground level inside the Cone itself.

The Cone is expected to cope with the food waste produced by the average family of four, but this can vary greatly. If you find you regularly have more waste than the Cone can cope with you may need another Cone to cope with all your leftovers.

If you find that in autumn and winter the digestion process has started to slow down and the waste in the basket doesn’t appear to be reducing, simply add a little more accelerator powder.

Why the Green Cone is a bear necessity

The Green Cone was designed by an engineer in Canada to solve the problem of bears pushing over rubbish bins to get to food waste. While bear-proofing may not be on your list of requirements, the Cone is sure to deter local foxes.

If vermin are a problem locally, you can add additional deterrents by hardening the area close to the Cone with bricks or rocks and by positioning the Cone away from fences, woodpiles and bushes.

If pet waste is to be added to the Cone, the unit should not be placed in soil where vegetables are grown or close to any water source. Pet waste should only be added  in small amounts and never in bags.

No bags of any kind should ever be added to the Cone as this will hamper the digestion process.

Why our Green Cone was a good buy

Before buying their Green Cone in 2009, Jack and Joan Milner, from Leicestershire, thought the prospect of being able to safely dispose of all their leftovers sounded almost too good to be true.

‘We were a bit sceptical at first,’ admits Jack. ‘We had already tried having a compost bin but we were not systematic enough to make it work.’

But at the time Leicestershire County Council was offering residents subsidised Cones to encourage them to recycle food waste at home instead of sending it to landfill. So the couple decided to give it a try.

A place in the sun

Under the scheme at the time, the council arranged for Green Cones to be installed on their residents’ behalf since the units must be dug into a hole in the garden.

 Once this was done, and the Cone was in place in a sunny spot near the kitchen door, the Milners began to feed it their leftovers, including bones.

‘It wasn’t long before the Green Cone was called ‘George’ (don’t ask us why!) and we fed him daily,’ says Jack.

 A pleasant surprise

The couple, now in their eighties, were quickly won over by George’s powers of digestion. ‘We have been very pleasantly surprised.’

Jack and Joan sometimes have to deal with the common problem of visiting dogs and cats leaving a little deposit on their lawn, but ‘George’ has even been efficient at dealing with this.

Most of the waste deposited in the Cone breaks down to become nutritious water that drains from the underground basket into surrounding soil. The Milners have noticed the effect of this soil conditioner on their garden.

A very good buy

Their Cone was placed in an arid spot which sported a few Lily of the Valley flowers and these soon began to flourish, becoming ‘a superb patch two metres in diameter.’

Jack adds that their Cone is now becoming a bit brittle but still ‘completely serviceable’, and it is only now after 13 years that it might need emptying.

‘Overall, George has been a very good buy.’

What’s in a name?

Incidentally, the Milners are not the only customers who have found themselves giving a name to their food waste digester. In our reviews section is a family who named their three Green Johanna Hot Composters Bertha, Belinda and Beryl. Whatever you may wish to call your Cone (and names are not obligatory, we don’t check!) we’re sure life with your own George, or Daisy or Engelburt will be just as good as the Milners’ experience.
