Is Your Compost Made of Sewage Sludge? | Planet Natural
When you spread sludge on farmland or use a bag of compost you bought at a nursery or home-and-garden supply that’s made with sludge, you’re also spreading contaminants. Some one-thousand contaminants have been identified in sewage sludge, a short list of which includes lead, mercury and dozens of other metals, flame retardants, steroids, organochlorine pesticides, plasticizers, hormones and antibiotics.
Sewage Sludge Fertilizers in Farms – United Sludge Free Alliance
Sludge on America’s Fields = Cheap Industrial Dumping – By promoting sewage sludge as a false fertilizer option to farms, home gardeners and parks, America’s food, water and communities are a cheap, short-term dump for businesses and industry. You are what you eat, America.
Sewage sludge as a sustainable fertilizer – Science …
Sewage sludge as a sustainable fertilizer. However, total phosphorus uptake from thermally conditioned sewage sludge was lower than that from the commercial fertilizer. This could be explained by the fact that the phosphorus in the water-soluble commercial fertilizer is immediately available for plant uptake after application,…
small scale organic fertilizer production line cost for sale …
Organic fertilizer production line or organic fertilizer production plant is mainly used for produce organic fertilizer granules. The raw materials for organic fertilizer production line or organic fertilizer production plant are all kinds of organic wastes, like animal manure (chicken manure, cow dung, pig manure, sheep manure),municipal sludge (MSW), food waste, agricultural waste (bean dregs, mushroom residue, palm oil waste, neemcake, vinasse draff, stalk), sewage sludge, industrial …
Is Sewage Sludge a Safe Fertilizer? What are Biosolids …
SLUDGE IN THE CITIES. If you get compost from a local recycler of municipal waste, you may end up with some form of sewage sludge. When you see the word “organic” don’t assume it is sludge-free. Ask specifically if it contains biosolids (Class A or B ).
granulator machine for fertilizer,fertilizer granulator …
Compound Fertilizer Plant Line with Rotary Drum Granulator. This rotary drum fertilizer granulator line is usually used for process compound materials such as urea, Dap, some rocks and other raw materials. With rotary drum granulator in the line, this line has adopt wet type granulation and the granulator capacity will larger. NPK Fertilizer Plant Line
Sewage sludge could make great sustainable fertilizer …
Sewage sludge could make great sustainable fertilizer. This could be explained by the fact that the phosphorus in the water-soluble commercial fertilizer is immediately available for plant uptake after application, whereas the phosphorus in thermally conditioned sewage sludge is present in a lower available form.
Biosolid Fertilizers: This Massive Scam Threatens Your Health
The problem is, the sludge approved for use in fertilizer also contains industrial waste, which is loaded with toxins and heavy metals. The EPA was created in 1970 as a result of the Clean Air and Clean Water Acts. Congress and then-President Richard Nixon created the agency to regulate environmental pollutants.
Frequent Questions about Biosolids | US EPA
The controlled land application of biosolids completes a natural cycle in the environment. By treating sewage sludge, it becomes biosolids which can be used as valuable fertilizer, instead of taking up space in a landfill or other disposal facility.

Bio Organic Fertilizer Granulator Machine is also called wet fertilizer granulator or stirring tooth granulator. It can granulate a variety of organic matter, especially be able to granulate the coarse fiber material which is difficult to be granulated by conventional equipment, such as crop straw, wine dregs, mushroom residue, drug residue, animal manure and so on. Also, organic fertilizer granulator machine has a good granulation effect on the humic acid, municipal sludge and other similar raw materials. The raw materials need not to be dried before granulation, after screwing, ball shape fertilizers will be out easily.
1.High granulation rate, dense granularity. The ratio can be 90% above.
2.Wet raw materials are available processing, no need drying before granulating.
3.No binder need to add, materials inside will grow inlaid with each other under certain force from organic fertilizer granulator.
4.Perfect ball shape fertilizers, moisture 20%-40%.
5.Heavy seamless steel pipe ensure stable machine running in bio organic fertilizer granulator.
1.Widely raw materials processing, especially wet raw mateirals.
2.Energy saving, can be screened directly after organic waste to fertilizer granulator machine granulating.
3.High granulating rate, 90% above with reasonable fertilizer granulator machine price.
3.Hard granules in ball shape, good performance.
4.Stable machine running, easy operating and maintain.
Composted materials can be sent to organic fertilizer production granulator machine with mixing. After materials enter into the machine through the feeding inlet, by the high speed rotating mechanical stirring force and aerodynamic force, the materials are mixed, granulated, spherified and densified in the machine, achieving the aim of granulation. The formed granules are pushed out in the other end of the home food waste to fertilizer granulator machine.
The diameter of the produced granules can be controlled by adjusting the quantity of the raw materials and rotating speed of main shaft. The less the raw materials mixed and the higher the rotating speed, the smaller the granulated fertilizer.
Q:what is the final fertilizer size from organic fertilizer production granulator machine ?
A: The final fertilizers are in ball shape. Final size will be 4-8 mm.
Q:what is the output moisture content ?
A: The final moisture content will be about 35% from fertilizer granule making granulator machine.
Q:what is the granulating ratio of home food waste to fertilizer granulator machine ?
A: The granulating ratio will be larger than 90%
Q:how long will these fertilizers store ?
A: if no drying, the store time will be 20-40 days. if drying, it will be 2-4 months
