The Next Generation of

Waste Treatment & Biogas Production​

SGTech is a multi-disciplinary CleanTech & Renewable Energy company specializing in Nutrient Recovery, integrated Biogas solutions and Water Recycling. SGTech focuses on the Livestock industry.

 

SGTech has developed an efficient and economical novel Anaerobic Digestion (AD) technology – Integrated Ecosystem Solution (IES) – that avoids the need to treat the Digestate produced in the AD process. The treated water can be discharge into the sewage and/or reused.

 

SGTech’s IES process is covered by International PCT application claiming a priority, and further by national patent applications in Israel, US, EU, Asia and other countries.

ABOUT US

SGTech also developed a revolutionary business model. SGTech is not intending to become a biogas and/or waste-treatment company. SGTech is a technological developer company with work in a unique royalty license model.  SGTech will provide the developer/SPC the technology in return to project lifetime royalties on the overall revenues.

 

This business model mutual benefits SGTech as well as the developer:

  1. Since the revenues of SGTech are derived directly from the project’s revenue, SGTech has a mutual interest in the success of the project.
  2. Reducing operational risk by relying on the developers to carry out the Engineering, Procurement, and Construction. 
  3. This business model creates the opportunity exponential year-to-year revenues, with a high growth rate.

 

We believe that this business model will allow SGTech to grow the biogas market size at a pace similar to that of other renewable energies.

DAIRY FARMS​

Sustainable Green Technologies (SGTech) is an Israeli multi-disciplinary CleanTech R&D Renewable Energy company. SGTech specializes in Nutrient Recovery, integrated Biogas solutions and Water Recycling of Livestock. SGTech provides design, construction, operation, and maintenance for wastewater treatment and biogas production facilities.


SGTech was established to give a valid environmental & economical solution for the main drawback of the Anaerobic Digestion (AD) technology for Livestock waste treatment: the formation of Digestate. Digestate are black water with very high concentration of pollutants containing pathogens and high load nutrients, whose disposal is prohibitively uneconomical.


SGTech’s philosophy is that environmental and economic interest does not necessarily contradict. Moreover, only when these interests meet, we can achieve a healthy sustainable life. Therefore, SGTech’s technology is aimed of achieving an all-win situation between all the market players.


SGTech has developed a win-win-win solution for the farmers-developers-regulators. We named it: Integrated Ecosystem Solution (IES). IES is an accelerated biological treatment, designed to protect the "3-triangle-ecosystem" – air, soil & water. Unlike the current best available AD technologies, SGTech's solution does not require additional chemicals, and is therefore more cost effective, efficient and safer. IES leads to a higher economic output with lower Capex and Opex, compared to traditional AD systems.


SGTech is the sole owner of the technology, with number of International PCT applications claiming a priority, in addition to national patent applications in Israel, U.S., the European Union, China, Russia, India and additional countries.​

Business model​

Integrated Ecosystem Solution (IES)

SGTech’s innovative solution for Nutrient Recovery and Biogas production - Integrated Ecosystem Solution (IES) – aims to redefine the standard Anaerobic Digestion (AD) processes known today. The technology addresses the full picture of waste treatment while avoiding the need of Digestate treatment. We achieve Nutrient Recovery which yield clean water up to the required level; for discharge into the sewage system and/or reused, together with, Renewable Energy production of electricity and heat from Biogas. And finally, a quality soil improver production for reuse in agriculture.

 

IES is an accelerated biological chemical free treatment designed to protect the

3-triangle-ecosystem:

  1. Air - No pollution from CH4, H2S, NH3 and N2O. Without the constraints of pollution, IES plants can produce more biogas for conversion to electricity & heat, depending on the local state energy requirements.
  2. Water - No pollution to watershed or ground water from runoff of NO3, TP, Na+, Cl-. Meets strict regulatory parameters for COD and BOD content, making IES a preferable choice.
  3. Soil - no pollution to the soil due to salinity from Na+, Cl-, B- and reduces pathogen threat to crops. IES provides farmers with a better alternative to conventional ammonia based liquid fertilizer.

 

Unlike the current best available anaerobic digestion technologies, SGTech's solution does not require additional chemicals, and is therefore more cost effective, efficient and safer. IES leads to higher economic output with lower Capex and Opex, compared to traditional AD systems. We believe that IES will allow dairy farmers to enhance production while reducing their environmental footprint.

SGTech currently has:

  • An up-and-running prototype in a dairy farm of 2m3/d (~530 gal/d), that meets the restrict Israeli’s regulation standards to discharge to the sewage. (CASE STUDY #1)
  • Dairy farm’s full-scale plant of 30m3/d (~8,000 gal/d) in a testing stage. (CASE STUDY #2). The total project will expand to treat cow manure of app. 400 cows, therefore, the influent will be approximately 60m3/d (~ 16,000 gal/ day)
  • We are aiming for additional project in Israel which treats cow manure of about 500 cows; influent of app. 75 m3/d (~20,000 gal/d).
  • We are currently developing 4 projects with strategic biogas developers in the US to implement the technology in 4 dairy farms. At the same time, we penetrating into the European market through strategic partnerships with a two leading European biogas companies; one has over 400 and the second more than 300 biogas plants worldwide.

LAB

SGTech has an in-house lab for developing new technologies and for analytical measurements. The first steps of SGTech’s innovative technologies were made in this lab. Today we have an up-and-running 2m3/d (~530 gal/d) prototype (CASE STUDY #1), and a 30m3/d (~8000 gal/d) full-scale plant in commissioning(CASE STUDY #1) in Israel.


The lab is equipped with the following measuring kits: COD, TS, TSS, TDS, DO, Ammonia, NO3, TP, TKN, CH4, H2S, pH, Alkalinity.
The current challenges of the lab are to improve and advance the technology to its 2nd generation; cleaner water (irrigation level), higher biogas production, wider %DM applicability, etc.

CASE STUDY #1

Milking Parlor (Milking Shed) ~2m3/d Wastewater Treatment Prototype

Sustainable Green Technologies (SGTech) is a multi-disciplinary R&D CleanTech & Renewable Energy company, specializing in Nutrient Recovery, Biogas solutions and Water Recycling for Livestock. SGTech developed a game-changing chemical-free economical feasible waste treatment producing treated water at quality for discharge into the sewage.
The technology was successfully tested in a prototype in an Israeli dairy farm for ~2m3/d (~530 gal/d) of a 1-2% DM waste. Table 1 & Figure 1 summarizes the system performance.  Figure 2 illustrates the treated water qualities.

CASE STUDY #2

Milking Parlor & Cowshed 30m3/d Wastewater Treatment Full-Scale Plant​

Sustainable Green Technologies (SGTech) is a multi-disciplinary R&D CleanTech & Renewable Energy company, specializing in Nutrient Recovery, Biogas solutions and Water Recycling for Livestock. SGTech developed a game-changing chemical-free economical feasible waste treatment producing treated water at quality for discharge into the sewage.

 

After successful 2m3/d (~530 gal/d) dairy farm prototype (CASE STUDY #1), the technology is being tested for a full-scale plant. We scale-up the technology for treating the entire waste of small scale dairy farm (~300 heads). The purpose of this CASE STUDY is dual; 1) proving the technology robustness in a “real” waste treatment. 2) Verifying the economical profitability of the technology.

 

This CASE STUDY intend to examine not only the Nutrient recovery, i.e. the treated water quality, but also the Biogas/Energy (electricity & heat) production, and the compost quality.  The technology will be tested in 2 stages: with 1) no additives, 2) added additives, e.g. chicken dung or whey up to 15%. Table 1 summarizes the system goals.
