Urban farming is the practice of cultivating, processing, and distributing food in or around urban areas. This includes growing plants and raising animals (or fish) within and around cities in spite of land constraints in the city.
i) Aquaponics (Integration of Aquaculture and Hydroponics)
Aquaponics is the combination of aquaculture (raising fish) and hydroponics i.e. involving a soil-less growing of plants and veggies with raising of fish in one integrated system. The fish waste provides an organic food source for the plants and veggies and the plants naturally remove the nutrients and treat the water to return to the fish tanks. Besides fish, veggies and green walls in our case, the microbes (nitrifying bacteria) are another party involved to convert ammonia from the fish waste into nitrites and then into nitrates. Nitrates are a form of nitrogen family that plants can uptake and use to grow. Solid fish waste is often turned into vermi-compost that also acts as food source for the plants and veggies. Aquaponics system thus capitalizes these benefits and eliminates the drawbacks of each other.
-High rise Building Aquaponics including Green Walls
Ecoclean’s has recently completed a pilot commercial aquaponics system on the 15th floor on a high rise building in the city centre. The aquaponics system is also served as education training for agroprenuer-ship and environmental/chemical engineering courses from local universities which dispatched their interns here.
As this is the first kind of the world high rise aquaponics involving our CDS technology and advanced nano-treatment technology, world reputable consultants were engaged and high-tech materials were imported from various countries.
Together with our deputy chairman who was the past president of the Institution of Engineers of Malaysia and our Managing Director Mr. Yale Wong, they have jointly written a paper which is now accepted as a poster presentation in the coming Singapore International Water Weeks ( SIWW) 2020.
This will be the 3rd paper submitted and approved by SIWW featuring all the technologies from CDS Technology, Nano Technology to current aquaponics system as a eco system thus complete the 20 years mission of EcoClean of having close the stormwater loop as recycled and reused water in the lights of water conservation of water.
With this Covid19, this demonstrated another source of agrofood production and increase the country’s food security and production against disruption of supply chain.
ii) Vertical Garden and Green Wall
We do not use soil for our vertical garden and Green wall especially for the indoor types as soil will bring dusts and related soil insects and disease. We use a Belgian soil management system called Vydro which is hydrophilics i.e. will hold water, air of the right proportion and slow release organic fertiliser which is what the plants need for healthy grow
We have vertical garden and green walls growing well and looked almost naturally grown without manicure pruning. They are however irrigated automatically twice a day.
iii) Vertical Farming using Green Matrix
We have also developed a Green Matrix system for vertical farming on a staggering arrangement of 3-2-3 layers so that the veggies can still get the maximum sunlight and harvesting is still within an adult person’s reach.
We believe we are one of the few to integrate this kind of vertical farming with aquaponics system so that we do not require any fertiliser and chemical to grow almost pure food within the city or perimeter of the city to fulfil the requirement of urban farming.
This will provide good food security and minimum road miles as a tasty and crunchy veggies within the city as a better alternative to organic farming or hydroponics.
