Recycling Waste into Compost
At WEIMAR, our upstream process involves the extraction of solid food waste from hotels, food and beverage outlets, restaurants, hospitals, schools, shopping malls, hypermarkets and the slaughterhouse. This waste would have been channeled into the local landfills, except that this disposal method widely contributes to water and air pollution.
While the modern, well-maintained landfill can be both hygienic and easy to recycle, poorly managed landfills have become a leading contributor to undesirable environment effects including wind-blown litter, breeding grounds for hazardous vermin and liquid leachate.
As of 2011, over 45% of organic waste ends up in landfills. The presence of organic waste also makes it much more challenging to process recyclable items in landfills such as aluminum cans, glass and paper which has been mixed together with solid food waste. This means that preventing organic waste from reaching landfill also improves the recycling rate of other recyclables as well.
The Formation of Leachate
Leachate is defined as the yellow, black or orange colored liquid produced whenever there is the presence of water in landfills. Leachate is also easily described by its acidic, offensive smell due to the high content of sulfur-rich organic species living in the deadly concoction.
The creation of leachate also encourages the harmful growth of bacteria and fungi as well, which in return releases even more water content to be converted into toxic leachate. The acidity of leachate is so strong that normally non-decomposable objects such as gypsum plaster and cement-building materials will also undergo a chemical reaction that is poisonous to humans.
The biggest problem with liquid leachate is that once it comes into contact with the local water supply, the contamination process is physically irreversible.
Methane gas is also released during the anaerobic fermentation process encouraged by leachate. While plenty of attention has been heaped on the role of Carbon Dioxide as a greenhouse gas, the Intergovernmental Panel on Climate Change (IPCC) has revealed that Methane gas can actually generate up to 23 times more heat as compared to Carbon Dioxide!
Save the Landfill, Save the World
Hence, rather than allowing the solid food waste to contribute to the escalating amount of landfill waste, WEIMAR has actively promoted the conversion of organic waste into compost by utilizing the On-Site Organic Waste Composting Machine.
The objective of the WEIMAR Middle-Stream is to:
- Provide local municipalities with a feasible and cost-effective alternative to increasing landfill waste
- Help meet the growing demand for organic soil enhancers and fertilizers
On-Site Organic Waste Composting Technology
Prior to the decomposition process at landfills, solid food waste such as vegetables and bones actually contain a high amount of nutrients, which can be converted into good quality compost or fertilizer. These products are not only good for the soil but are also environmentally friendly, healthier for humans and is also much more economical as compared to industrial chemical fertilizers.
The compost which has been converted from solid food waste is then resold back to fertilizer manufacturers, landscapers, nurseries, farmers, golf courses and government agencies.
At WEIMAR, we also actively encourage our Upstream customers to coordinate their own compost exercise as well in order to save on the costs of transporting solid food waste from their location to our processing facilities. Hence, our Middle Stream industry is based on helping interested parties setup and process their own organic waste compost on location site.
Top Five Benefits of Turning Waste into Compost
COST : Save on transportation and middlemen handling costs as our On-Site Organic Waste Composting Machine empowers anyone to turn food waste into compost.
You can then use the self-made compost on your own garden or for landscaping activities. Alternatively, feel free to sell your compost for a neat profit. The interesting thing about organic compost is that plants only require a minimum amount of fertilizer to promote its growth as soil aeration, soil drainage and the addition of beneficial soil organisms is perceived to be just as important.
HYGIENE : Have you ever noticed that most garbage compactors stink? This is due to the fermentation process and the production of leachate water in the vehicle, which makes this mode of transportation unsuitable for handling organic waste. Long-term usage of such vehicles will actually promote the habitation of insects, rats, fungi, worms and other hazardous vermin.
REDUCE LANDFILL : On-site conversion of food waste into compost also means that there will be less items being piled up in landfills, which then saves valuable landfill real estate space.
GO GREEN : A smaller landfill pile also means that environmental issues such as global warming and climate change can also be better controlled as well. The production of leachate will be reduced, which then lowers the risk of water contamination.
Similarly, as less Methane gas will be emitted in landfills, global warming is also better contained. A garbage compactor that does not have to travel from your house to the landfill also significantly reduces your carbon footprint in terms of diesel that would have been used.
- GO ORGANIC : Just like how organic food is healthier as compared to produce that has been infused with pesticide, organic compost is also a better option when compared to chemically laced fertilizer. Studies have shown that chemical fertilizers tend to encourage the rapid growth of plants that are structurally weak. Fillers used in chemical fertilizers can also potentially harm the plants, your health and the environment as well.
Organic fertilizers on the other hand do not contain fillers and strengthens the structure of the growing plants, albeit at a slower pace. In other words, turning organic waste into compost is a great way of promoting sustainability while also prolonging your lifespan and protecting the environment.
Household Composting Unit
At WEIMAR, we support composting activities, even on the smallest scale. As such, we also offer Malaysians the opportunity of creating their own organic compost right in the comfort of their own home.
According to Forbes Magazine, urban agriculture is predicted to experience a 20% growth in the next 8 years due to the increasing cost of living coupled with the growing awareness of living a greener life.
As daily expenses increase in line with the rise of petrol prices and meal costs, the average Malaysian is faced with the dilemma of a shrinking retirement fund in proportion to the decrease of food quality and quantity. Sadly, the standard quality of food served in most food stalls, cafes and restaurants are also decreasing in lieu of rising food prices, which means that most of us are faced with an increase in health care costs as well.
The good news is that anyone can now create their own compost at home and cultivate their own fruit trees and vegetable plants for personal consumption.
Most large-scale agriculture companies make use of chemicals such as herbicide, pesticides and fungicides to accelerate the growth of their produce without taking into account the longterm effects to the consumer's health and soil condition. While these chemicals can provide targetted results, it does not fix dysfunctional soil problems nor promote better health.
On the other hand, our composting technology includes the introduction of Efficient Microbes (EM) in the soil, which then promotes better nutrient cycling. Besides that, composting the soil is also a much better option as opposed to replacing dead soil that is void of nutrients and minerals.
These microbes also suppress the growth of dangerous organisms while also accelerating the production of the compost as well. Unlike pesticides, herbicides and fungicides which are harmful to humans, Efficient Microbes are also non-pathogenic to humans.
Bokashi is a Japanese term referring to organic matter than has been fermented. Hence, the term "Bokashi Composting" literally means to create compost by fermenting organic produce. This process literally converts ordinary kitchen food waste such as meat, dairy, vegetable and small bones into nutrient-rich homemade plant food.
Bokashi composting has become a popular pastime for nature lovers as this composting method is two times faster relative to traditional composting. Specifically, this composting process can be completed in less than 2 weeks, which also makes it the fastest nutrient extracting method currently available.
More importantly, Bokashi compost can be processed indoors, without any worries of creating foul-smelling odors or releasing gases such as Methane.
Bokashi Tea Benefits
Besides processing fermented food waste, Bokashi Tea is also produced from the Bokashi composting process. Bokashi Tea is liquid produced during the food fermentation process, and is found to literally contain all the nutrients found in the food waste, including 30 different species of microbes which is beneficial for plants and trees.
Bokashi Tea also contains 17 times the amount of nutrients in traditional compost, which means that it is a highly potent plant fertilizer. Bokashi Tea can also be used to unclog drains and it can also reduce the smell of ammonia produced by kitty litters. Like the fermented food waste produced, Bokashi Tea is also harmless to both humans and animals.
How Do I Bokashi?
The Bokashi Compost unit is compact enough that it can be placed under the kitchen sink. To create your compost, all you need to do is combine food waste and the Efficient Microbes in the containment unit. This concoction is then sealed in the Bokashi Compost unit to create anaerobic conditions, which is vital in creating the ideal environment for fermentation.
The semi-fermented product can then be transferred into the soil after two weeks, following which the full decomposting process can then take place. The revitalized soil can then be added to seeds, plants or trees.
Do note that Bokashi Composting is not suitable for composting liquid, rotting food or big bones.
Recycling Waste into Biodiesel
The two components extracted in the Upstream process are solid food wastes and FOG (fat, oil and grease). While the solid food waste can be converted into premium compost, the FOG extracted can similarly be processed into clean energy in the form of biodiesel. After all, the alternative would be to dispose of the FOG liquids in local landfills, which can only worsen environmental conditions.
Biodiesel Conversion Technology
It is estimated that our Biodiesel Processor can produce between 150 liters to 900 liters per production run with an efficient 1:1 conversion ratio. This means that every drop of fat, oil and grease passed through the machine is converted into biodiesel. At the same time, no other intermediate compounds will be produced, which makes this process a green cycle. Each conversion of 150litres of biodiesel is also estimated to take a mere 30 to 45 minutes, depending on the size of your unit.
Our Biodiesel Processor operates at a low temperature and pressure, which means that minimal energy is required to process the liquids. The dry wash biodiesel processing models have also been found to meet the global benchmarked standards of biodiesel used in vehicles.
Biodiesel vs Diesel
As the cost of petrol and diesel methodically raises throughout the years, it is a long term goal of WEIMAR to provide an alternative energy source in the form of clean biodiesel which can be easily extracted from fat, oil and grease collected in the Upstream process.
Diesel produces sulphur, which is a prime contributor to air pollution. As the usage of diesel in heavy vehicles is particularly harmful to the environment, WEIMAR also plans to dampen the heavy independence on all fossil fuels by encouraging the usage of environmentally friendly biodiesel alternative.
Biodiesel on the other hand is the only alternative fuel to have completed health effects testing requirement. The emission of hydrocarbon is also 50% less than that measured for diesel fuel. Furthermore, carbon dioxide emissions can also be reduced by up to 78% when biodiesel is used over diesel.
