The HH-2 Horticultural System (HH-2)

The HH-2 Horticultural System (HH-2) is slowly gaining recognition as the most highly effective solution to many modern day agricultural and waste problems. There is an urgency to address worldwide food shortages and waste issues. HH-2 has the potential to be a “game changing” technology – but financial resources are required to bring this methodology into widespread use.


Problem One

Current systems of agriculture and horticulture plough and dig over the soil, thereby losing valuable moisture and carbon, which is consequently depleting the soil at an alarming rate. The world is losing 24 billion tons of topsoil every year. The depletion of the organic life in the soil increases the requirement for ever more chemical fertilisers and pesticides.

In Africa poor and overworked soils, lack of resources to buy chemicals to keep off pests and disease, and water shortages are all to blame.

 

Problem Two

Africa and other developing regions throw away human and other wastes in such a way that causes pollution by the contamination of water courses and the breeding of rats and other pests – the largest cause of loss of life in the world (WHO).

 

 


One Solution to Two Problems

With over 20 years of research The Howard-Higgins Horticultural System has perfected their HH-2 System as the solution by turning school, hospital, town, village and rural waste into a unique soil preserver and rejuvenator in only 90 days. This low cost technology is easily operated by the school and hospital pupils and staff, townspeople, villagers and others, thus creating a valuable food source and an income for them – one of the surest ways to bring them out of poverty.

The HH-2 Horticultural system will:

  • Turn human and other wastes into a valuable soil preserver and rejuvenator – within 90 days
  • Eliminate water pollution, rats and flies from rubbish piles
  • Produce an optimum fertiliser to grow pest and disease free crops
  • Dramatically improve the nutritional content of food produced
  • Help educate users in simple ecological waste management and good practice agriculture
  • Create micro businesses with income generating activities
  • Help reduce malnutrition

 

How HH-2 works

The “secret” of the HH-2 system lies in the culture of the initial specific fungi and the subsequent bacteria that use thermophilic actions to make a potent fertiliser/soil “conditioner” from the measured inputs of waste products.

The HH-2 then enables the right fungi and bacteria to grow and develop whilst maintaining the correct moisture balance to ensure an optimum heat curve.

This is all achieved through the use of the HH-2 “Hot Boxes” which are filled with any organic waste including:

  • Farm waste
  • Household waste
  • Cooked food waste
  • Animal waste, cow dung etc
  • Human waste from the HH-3 DRY Toilet system (see below).

 

Additional locally sourced “ingredients” are then added to the mix to start the unique cultures growing, creating HH-4, the most micro-organically active substance on Earth, with supremely effective carbon sequestration properties

No harmful pathogens have ever been found in HH-4.

 These specially insulated Hot Boxes are designed with no moving parts or electrical hook up and can be operated by unskilled workers after training. The remarkable end product, HH-4, is produced in only 90 days.

The Complete HH- 2 System

Richard has designed and developed the HH-3 DRY Toilet that requires no water for flushing.

The HH-3 DRY Toilet collects fecal matter through an ordinary looking toilet. Two options are available for using this toilet system:

  1. For communal applications the toilets are fitted in safe and secure cubicles on a raised toilet enclosure. The waste passes directly into the HH-2 Hot Boxes.
  1. Alternatively a biodegradable liner is fitted inside the toilet which very cleverly filters excess liquid into a collection system for recycling. A weekly collection system is organised on a localised basis with replacement bioliners that are placed in the toilet receptacle at the time of collection.

There is no need to flush the HH-3 DRY Toilet with water. There is no smell or unsightliness at any stage of the system.

The HH-2 and HH-3 will replace the need for the digging of pit latrines and can convert the inner working of UDDT toilets anywhere. Contamination of ground-water from badly managed sewage systems is the greatest cause of disease on earth (WHO).

When HH-3 DRY Toilets are fitted into individual homes, a pair of HH-2 hot boxes have the capacity to handle and sanitise the waste from 24 houses. This collection system will be income generating and self-sustaining.

The Unique Properties of HH-4

In a time frame of 90 days the HH-2 System produces a material, HH-4, which when applied correctly to the soil rapidly reproduces all the necessary organisms that make up a healthy soil structure. This automatically reduces the incidence of pests and disease to an absolute minimum.

This HH-4 material also facilitates the macro element, namely earthworms. These lowly creatures are ignored in modern day agricultural and horticultural systems and this is unfortunate as they produce 5x more Nitrogen, 7x more Phosphorus and 11x more Potassium in their castings than is found in surrounding soil (Balfour).

 

 

 

So potent is this “conditioner” that the need for yearly ploughing ceases. The natural soil profile is restored, compaction is avoided, rainfall is captured and carbon is continually sequestered. This together with revised surface water management prevents soil erosion and will enable the production of sustainable pest and disease resistant crops. 

Any school or community can grow its own fruits and vegetables with a much higher standard of nutrition than conventionally grown food completely organically and without digging the soil.

This improves the microbial life in the soil, the health of the plants grown upon it and the health of everyone who eats food grown in this way. Thus the children and staff in each of our school projects will have increased health benefits. The Nutritional quality of their diet will change and the children’s full capacity for development will be realised. Plus they will be learning the most important skill of how to produce their own healthy food.

They will be able to produce abundant food without the risk of polluting their irrigation and drinking water.  With this system digging or ploughing will disappear. Weeds will disappear also and large amounts of water and carbon will be saved.
