Composting accelerates the natural process of biodegrading or rotting down organic waste material into a rich soil or compost. Its a great and sustainable way to deal with our waste.
As I’m sure you know biodegradable waste does not do well in the unnatural conditions of landfill. It bubbles away producing methane which adds to the greenhouse effect. Composting biodegradable waste on the other hand produces a nutrient rich material that can be used to grow more food.
How It Works
All natural (as oppose to synthetic) materials do eventually biodegrade or rot. Composting speeds up that process
Useful composting information
Biodegradable –Biodegradable products break down through a naturally occurring microorganism, such as fungi or bacteria over a period of time. More about biodegrading HERE
Compostable – To be classed compostable, items must biodegrade within a certain amount of time, the resulting biomass must be free of toxins, able to sustain plant life and be used as an organic fertilizer or soil additive.
Home Or Industrial Composting?
Industrial composting are large scale schemes.
Home composting is a bin in your back yard.
The difference is is that industrial composting is a lot hotter and can work more quickly.
Therefore, while a product might be classed as both biodegradable and compostable, it might not break down in a backyard compost bin.
Case Study – A Cafe
Cute Boscastle National Trust Cafe uses compostable disposables and “. we collect the cups, cup holders, plates and the untreated wooden cutlery that we use, and they are taken to a local farmer who shreds them. He then mixes them with his green waste and composts them into a peat free mulch substitute. This mulch is hen taken to the National Trust plant nurseries at Lanhydrock House near Bodmin, who grow, amongst all the other plant, the plants that are sold in the National Trust shop that adjoins the cafe in Boscastle. By doing it this way, we not only successfully recycle the disposables from the national Trust Cafe in Boscastle, but we contribute to saving the limited resources of peat bogs.”

Community composting is where local community groups share the use and management of a common composting facility.
Community composting is where residents jointly share and manage a central composting facility.
Community composting allows people to compost food and garden waste who may otherwise struggle to do so.
Community composting has an added benefit of bringing the community together.
Guidance is available for overcoming practical difficulties which may arise.
Grant funding may be available to cover costs.

The UK composting industry has experienced a period of strong growth, according to figures released today. The amount of waste composted in 2007/8 rose by nine per cent from the previous year and further growth is predicted in the annual WRAP and AFOR survey.
As demand for composted products continued to increase, the industry turned over more than £165m in the year to April 2008. In total, 4.5 million tonnes of separately collected waste was composted in the UK in 2007/2008.

New York City Mayor Michael Bloomberg announced a plan to increase composting of food scraps generated by the city’s eight million inhabitants. In a few years, separation of food waste from other refuse could be required of residents, the mayor said.
The administration says it will soon be looking to pay a local composting plant to process 100,000 tons of food scraps a year, or about 10 percent of the city’s residential food waste.Read more here.

The New Litter
Companies using compostable plastic.
Our new innovative packaging, developed by Israeli start-up TIPA, is just as durable and impermeable as ordinary plastic – but it biologically decomposes within just 180 days and becomes a fertiliser for soil, behaving similarly to an orange peel. Read more here.
A while ago I got sent some Vegware stuff to review. Vegware make disposable, compostable packaging for the fast-food industry. Hooray for them …. but I am not in fast food. So what would I be using them for? For starters…

Why This Post Is ….
A little bit rubbish. You are reading a work in progress. Here’s why…
The case against incinerating rubbish and a proposed zerowaste alternative involving composting on an industrial scale – damn good stuff. Copied from eplanning.derby.gov.uk
STATEMENT FROM DR PAUL CONNETT:
Nanoparticles from incinerators or gasifiers or gasifying incinerators use household waste as a fuel which due to its make up has the potential to contain every toxic element used in commerce – which means that it has the potential to emit nanoparticles containing those toxic elements. Diesel fuel contains far less of an array of toxic elements therefore comparisions of nanoparticle emissions from traffic with high temperature incineration or gasification is like comparing chalk and cheese.
Incineration and gasification does not destroy toxic elements- toxic elements in – toxic elements out. Gasification companies make inflated claims about what they are going to do with their products, but the char, or glassified melt, and the fly ash by-products, all contain toxic materials which are permanent in the case of metals and highly persistent in the case of dioxins and furans.
About 4 X more energy is saved reusing, recycling and composting the waste stream than burning them to create electricity so this proposal should not be considered a sustainable waste treatment process.
These proposals will directly impact on recycling and remove the drive to zero waste.
The key to sustainability (see my essay Zero Waste a key Stepping Stone to Sustainability) is Zero Waste. Everybody makes waste and as long as we do we are part of a non-sustainable way of living on this planet. But given good leadership everyone could be involved with the critical first step towards sustai
nability: source separation.
With source separation we can get out the organics clean enough to get them back to the soil, and recyclables which can be returned to industry – cutting out the huge energy demands of extraction and transport of raw materials, often half way around the planet. With the reuse of whole objects, we can create many jobs and small businesses, stimulate vital community development, and save even more energy by avoiding manufacture as well as extraction. But the single most important thing we can do is composting: composting sequesters carbon, if this material is burned it the Carbon is immediately converted into carbon
dioxide (global warming). Also by removing organics at source it makes it very much easier for cities to deal with the remainder of the materials – glass, metals, paper, cardboard, plastics, ceramic etc.
Burning ( or destroying) materials to recover energy is always second best. the number one priority is to recover materials and thereby conserve the embedded energy discussed above.
24 years ago promoters of incinerators tried to corral this issue between landfills and incinerators. you either burned it or you buried it. They scoffed at those like myself who argued that comparable reductions to incineration could be achieved by a combination of recycling and composting. But we have won that battle there are many small and large towns who are getting over 70% reduction with composting and recycling – incinerator only gets 75% reduction – you are still left with 25% as ash. You don’t get rid of landfills with incineration or gasifying incinerators. Note right mow San Francisco is getting 73% reduction without incineration, at a fraction of the cost of an incinerator and with many more jobs created.
Many of the proposals for gasification plants are coming from companies which have never operated such plants. There is a world of difference from small scale pilot plants and a fully-fledged commercial operation. here are very few
of these operations burning municipal solid waste. no one should entertain for a moment such a company coming to town unless they can establish some kind of solid track record – somewhere! A track record which can demonstrate what there emissions are and what they are doing with the byproducts. At the very least they should be required to a give a very careful written and documented response to Dr. Vyvyan Howard’s paper on nanoparticles, health and incineration. Right now they can promise anything because there are NO regulations for nanoparticles from incinerators or gasifying incinerators.
Highly exaggerated claims are being made with NO DATA to support them. When these
companies promise the earth it is probably because
they never expect these plants to run for more than a few years. The name of the game as far as I can see it is that they set themselves up as a “green & sustainable” entity promising to produce “green energy” and “fight global warming” a) to seduce local decision makers and b) to suck up any soft European money for green alternatives as well as PFI – once this is in the bank watch out for
them selling out the contract to some other company and/or go belly up with the principals walking away with a lot of the cash in their pockets.
Of course, they will argue that they agree with us that recycling and composting are important, but all they want are the residuals. But the residuals are the evidence of bad industrial design – so rather than destroy them we have to say if we can’t reuse, recycle or compost anything you shouldn’t be making it. This is how we can go from the current 70-80% diversion rates up to about 95% diversion over the next 10 years or so. this is the future.
Incineration simply burns the evidence that we are doing something wrong – and will delay by 25 years the crucial move towards sustainability. The Zero waste approach makes more sense on every front: economically, environmentally, and globally.
