How do I Prepare for My Garbage Guzzler?

The Garbage Guzzler is a great story for your premises. Not only are you becoming more environmentally friendly, but you can use the output it creates, and completely divert your food waste from landfill.

Garbage Guzzlers are simple to use, but you might have to make a couple of changes to the way you collect and sort your food waste to make sure that you get the best out of your machine. Based on our experience we’ve put together a few  tips to help ensure that you’re ready for a waste digester, and that you and your staff get the best out of it.

If you have any further questions, there’s also an FAQs section at the bottom of the page, or if that doesn’t answer your question or you would like some more information, please contact us.

Food Waste Separation

If you are not already separating your food waste at your site, you will need to do so. You’ll also need to consider how you manage this with your staff. In most cases, simply adding new bins (either in your kitchen or in your bin store area), which are used solely for food waste will get you off to a great start! However, you need to ensure that your staff are clear what can and can’t go into them.

Feed at Set Times

To make sure you know that the Garbage Guzzler is being fed the correct amount of times each day, it’s a good idea to implement set times to put food waste into it. This will stop any ad-hoc feeding of the machine, which can lead to overfilling and may also disrupt the digestion process, if food waste is added too many times during the day.

Take Ownership

It’s also wise to have a couple of staff who will take ownership of the Garbage Guzzler once it’s on site, so that you know that it’s being fed the correct amount of times each day, not being overfilled and that nothing’s going in there that shouldn’t be. While we’ll provide you with full training for this, you’ll be surprised how quickly your staff become experts in the machine’s operation and the output that it’s creating. This won’t be a huge change to the way that your staff operate, and once familiar with the machine, won’t impact on existing day-to-day operations.

Promote the Benefits

While it might be a bit of a culture change at the start, it can also be immensely rewarding. We have found that staff quickly buy into the new processes for dealing with food waste on site, which will then filter through to any new staff joining your organisation. Additionally we’ve found that both staff and visitors at a site are genuinely interested in how the Garbage Guzzler works and what it creates. It’s also a great story to promote internally, and to use in your CSR or environmental policies, so make sure you remember to promote it!

Operating FAQs

The following section covers the most frequently asked questions regarding Garbage Guzzlers, however please contact us if you would like any more information.

Aerobic digestion is a process by which micro-organisms break down organic material in the presence of oxygen. The process of enzymes and heat rapidly consumes waste food, releasing the water contained inside it.

No. Anaerobic digestion is a process which takes place in the absence of oxygen. The process takes much longer, and is used to create biogas (methane) which requires specialist handling and storage requirements. Anaerobic digestion plants tend to be much larger commercial waste treatment centres, rather than a technology and process which you can use at your location.

The Garbage Guzzler is a food waste digester and should be used for this purpose. If you are looking to dispose of compostable packaging, you are able to put this through a Garbage Guzzler also, however it will need to be shredded and mixed with food waste when being digested.

If non-organic waste goes into a Garbage Guzzler then it will not be digested. Due to the augur that turns inside the unit, it is however likely to get a little dented or bent! If you have put some non-organic waste into the Garbage Guzzler there is a small chance that it could cause damage or block the machine. The digestate inside the machine is hot, and you should not try to remove the material unless you have suitable apparatus to do so. If you believe that non-organic waste has been put inside the Garbage Guzzler you should contact us for advice.

The Garbage Guzzler can digest up to 280 litres of food waste each day. That’s more than a wheelie bin! Waste must be added to the Garbage Guzzler over 3-4 separate periods over 24-hours and must not be overfilled. The Garbage Guzzler also requires a period of 12-hours uninterrupted, to digest waste each day – but this normally happens between the last feeding at night, and the next feeding the following day.

Yes! The Garbage Guzzler can reduce food waste in volume by up to 70%, but that’s not all. You can use the output as a soil improver or biomass fuel meaning that it’s possible to divert all of your food waste away from landfill.

BSI PAS 100 Compliance aims to specify a standard and conditions that materials are composted to , so that users know which materials have been composted to a good quality standard and which have not. The standard was sponsored by WRAP (Waste and Resources Action Programme)  and developed in association with the Association for Organics Recycling. The standard has been adopted by the British Composting Association.

The WRAP website provides more information regarding PAS100 and what is needed to achieve it, which can be viewed just here.

With a significant reduction in your food waste, you will have less waste to collect and therefore be paying less to have it collected. Additionally, you can use the output as soil improver to mix in with compost to use on your land or planter or,  if you have a biomass boiler, then the output can be used to supplement the fuel you are putting into it. If you don’t have a biomass boiler or don’t need the soil improver, you can always consider selling it to those who do!

There are lots of environmental benefits to using a Garbage Guzzler. Not only are you sending less to landfill, but you are also helping to reduce vehicle movements associated with waste collections. Food waste can be put through the machine on a daily basis, helping discourage vermin around your bin areas and reducing the smells associated with rotting foods. The Garbage Guzzler does not use water as part of the digestion process, as is the case with some other technologies on the market, and only some of the condensate vapour which ends up being released as part of the digestion process ends up going into a drain. No methane is released from food waste going through a Garbage Guzzler, and the carbon which is already present in the food, is stored in the digestate and not released back into the atmosphere.

Typically, the digestion process takes 24-hours, in which time your food waste is reduced by up to 70%

The Garbage Guzzler is fitted with a carbon filter which reduces any odours released during the digestion process. There is a slight odour created during the digestion process, although it is not pungent. The smell is not dissimilar to that created by a brewery. As food waste is digested so quickly inside the Garbage Guzzler, it does not create a smell of decomposing food.

The enzymes used inside the Garbage Guzzler are self-replicating. Once heated to 55 degrees C they start to digest the waste, and regenerate as part of the process. Unless the Garbage Guzzler is fully emptied, there shouldn’t be a need to replace the enzymes, unless it’s been flooded or you put in something you shouldn’t have! Even if the machine if left dormant for a period of time, in most cases the enzymes should re-activate once the Garbage Guzzler starts to heat up.

If particularly cold waste is put into the digester the temperature might fall below 55 degrees. Additionally, if a lid is left open by mistake, this might also cause the temperature to drop. If this is the case, the Garbage Guzzler has elements inside it that will heat the inside of the machine back up to the required operating temperature. Additionally, an augur inside the digester turns and mixes the material inside the machine regularly, so new waste is very quickly mixed with warmer digestate inside the Garbage Guzzler, to help bring it up to temperature.

In most cases you simply add food waste and press a button on the Garbage Guzzler to start it working again. There is rarely any need to add any more enzymes unless it has been completely emptied. If you are digesting really wet waste, adding wood chippings will help the process and ensure your output is of the right consistency.
