Compost: Composting with the garden bin composter


 

The Garden Bin Composter.

AEROBIC COMPOSTING is the most common form of home composting for garden and kitchen waste. Theirs plenty of links below to sites with re-sourcing information about this composting technique, we've skipped the basics while concentrating our experience on Hot Batch Composting. This technique is suited to our urban environments and when performed well, produces good safe compost in the quickest possible time for the least input of human resource i.e.; your valuable time and effort.

PEAT-BASED COMPOST The compost sold in garden centres doesn't come from compost heaps, most of it comes from peat bogs. Peat is formed over many years from the remains of plants and provides an important habitat for a whole range of birds, insects and plants. This natural habitat is seriously under threat from peat extraction, the equivalent of 60 million bags of peat-based products are sold to UK gardeners every year! Although you can rely on peat-based compost to perform consistently itís not a good source of nutrients and contains very little biological activity, so compost manufacturers add nutrients to boost its chemical fertility. A more sustainable way to meet the demand for plant growing media and soil conditioners would be to use locally produced home compost.

URBANWASTE REDUCTION Making compost from garden and household organic waste is one of the most environmentally beneficial activities you can participate in, its simple and it reduces pollution, cuts down on landfill and saves money. 30% of rubbish is organic waste, it's removal from waste bins allows other materials to be recycled, making composting the starting point of all good urbanwaste systems.

COMPOSTING breaks down household and garden material into basic nutrients that are soil enhancing. It's an easy way to reduce household waste while improving the nutrient value of your garden and potting soil. Basically, composting requires mixing different types of organic materials with air and water. These materials then break down with the help of heat and countless microbes, fungi and other micro-organisms the ďmicro-heardĒ. Compost can be used as a conditioner to enrich soil and increase its ability to hold moisture, nutrients and oxygen. The result is a cost-free, chemical-free soil enricher that provides your plants with nutrients such as nitrogen, potassium, and phosphorous. Why ever buy topsoil or compost again? Donít be put off,  believing it to be dirty and smelly or too scientific, not true! Itís a natural process simple to accomplish and we hope we can show you how.

FACTORS AFFECTING THE RATE OF DECOMPOSITION Oxygenation. Oxygen is required for respiration by all aerobic inhabitants within the compost, the addition of 10% chipped wood to the compost ingredients will greatly improve ventilation throughout the pile. Temperature. The optimum temperature for fast decomposition is between 320C (90)F and 570C (135)F. Locate a bin for maximizing radiant solar heat, choosing black coloured bins for UK's cooler climate. Water Content. An efficient Composter needs to have a moisture content of around 60% (feels like a wet sponge) Under-watering is the single most common factor effecting slow composting while over-watering is the number one cause of odours. Surface Area. This is very important, to maximize surface area, shred or chip all paper and woody waste into small pieces. The more area you expose to micro-organisms, the larger the dinner table, and the faster the decomposition. Carbon/Nitrogen Ratio. A composting fundamental, organic materials rich in nitrogen, Greens (fresh veggie scraps or grass clippings), while carbon rich materials, Browns (hay, twigs, dried leaves, paper and cardboard) need mixing in correct proportions. A good general rule of thumb is to use 3 parts brown to 1 part green by weight.

AEROBIC BATCH COMPOSTING is the technique of preparing the correct quantity and type of composting ingredients, mixing for aeration and adjusting moisture content, before starting the composting process. All the work is carried out on the same day when loading the compost bin, which is then left to compost without further input. This eliminates weekly decanting of the bin contents for turning, mixing or moisture adjustment. Batching compost requires the collection and storage of ingredients outside of the compost bin, this system is sometimes referred to as "the three bin system" storing, composting and finishing off, each with its own bin. We advocate the use of only one good quality compost bin, such as The Garden Bin for the composting stage, with adequate storage for the collection of compostable materials.

  IF YOU NEED TO COMPOST WITH AN AEROBIC BIN, THIS IS THE ONE.  

Conventional Aerobic Bins. Aerobic Composting with The Garden Bin.
Various capacities 

 

Small in/out openings.

Separate lid  

Supplied without base.

 No vents.

Normally necessary for lid removal to vent the pile.

No base drainage.

 

Normally supplied in green.  

The need to weekly remove contents, turn by hand and replace contents. (conventional compost thinking advises this backbreaking, time consuming course of action to aerate the contents)  

Large 325 litre capacity, with low profile, for batch loading and thermal retention while remaining unobtrusive.

Large removable split hinged lid, enabling a quick fill of batch loads or smaller additional loads. Two Large outlets enabling the easy removal of finished compost by garden spade.

Attached split hinged lid stays with the bin at all times.

Unique aeration base allowing air flow by convection through the hot pile.

Vented body to exhaust convected air without the removal of the lid.

The lid remains in place during ventilation containing moisture and protecting against the ingress of rain.

The base allows over-watering runoff, stabilizing moisture content. Earthworms and invertebrates can still access the bin through the base.

Constructed and supplied in black post-consumer recycled plastic, attracts and retains radiated heat.

No requirement to turn the contents, constant ventilation is achieved by the bins design, additional ventilation and clump breaking is achieved by the simple use of a compost aerating tool. 

Our Composting Tips

  • Place your Garden Bin Composter in the sun on ground with good drainage.
  • Collect a good mix of materials with the correct C:N Ratio.
  • Add 10% chipped wood or bulking material to create aeration voids in the mix.
  • Inoculate with composted material.
  • Soak well with un-chlorinated water, rain water if possible, until the material feels like a squeezed out sponge.
  • Load composter in layers all in one go.
  • Check compost temperature after a few days.
  • Add moisture as required.
  • As the material compacts aid aeration by loosening the composts structure with a compost aerator.
  • No Meat. Oils. Fish. Bone. Diary products. Animal or Human waste. Glossy coloured print. Plastic coated cardboard. Conifer and evergreen material.
  • Compost has a pleasant aroma. Bad odours only occur when there is a lack of oxygen, too much wet nitrogen rich material or too little carbon material.
