Wastewater �Treatment Plants�. �This� may present reg����'��,5�"�`echnical �and financial impacts to�
�the Wastewat�r�Utility.
Background/Analysis
Staff is proposing to engage a consultant to assist with planning and design of a small-scale
pyrolysis unit to better prepare the City of Redding (City) to comply with environmental
�regulations and provide a long-term sustainable solution to the disposal of biosolids from� both
wastewater treatment plants. The handling and disposal of biosolids is� highly regulated, with
continuously evolving environmental legislation�in the State���of�California. The�City of Redding�
�(City) curren�ly disposes of this material at the local landfills�.
Report to Redding City Council September29, 2020
Re: 4.11(h)--Authorize Biosolids Pyrolysis Project at CCWiNTP Page 2
�California �Senate Bill (�SB) 1383 codified� California's commitments to reduce� greenhouse� gas
emissions and air pollution �tatewide. It identified methane emissions�from landfills as one area
to address in order to meet California's target to reduce Green House��Gas emissions 40 percent
bel�ow 1990 levels by 2030. SB� �13�83 enhances� California's efforts to� achieve �the statewide 75
percent recycling goal by 2020, established in�California Assembly Bill (AB) 341, a�d
strengthen the implementation of�mandatory commercial organics recycling established� in AB
1826. As AB 341 set the roadmap to find� beneficial� uses for organics and divert them from
landfills, AB 1594 specifically phases out the credit allowed from biosolids being utilized as
�"Alternative�D�aily �Cover"� for landfills� and classifies all green was�e as regular disposal�. What�
�this� means is landfills ar�� being forced� to �divert orga�ic waste; including� biosolids, whereas
landfill disposal of biosolids will not b�e�a viable�option in the future.
More recently; the 5,��, ;{�,��;���t{�������urces Control Board (SWRCB) issued an order requiring all

Pyrolysis is the process of burning without a ��j rjjt�; utilizing h�;����produced to thermally remove

�The�potential benefits�of p�rolysis�include the�followin� ,�at� �t,�t,�; �
1. A reduction of biosolids in volume and weigl��r��;`����,i�'�� percent, could be achieved,
thus�sub�stantially reducing storage�and hauling�ct��`��`:�`'"��
2. A high percentage�of the carbon content of the materiaL processed is retained in pyrol�sis
biochar, resulting in less overall carbon dioxide emissions (i.e. sequestration).
3��. Biochar�has the potential to�be used as a soil amendment or replacement for �arbon black��
in an i�dustri�l ma�ufacturing process.
4. Since pyrolysis does not fully combust the material being processed, compliance with air
�quality requirements for the system exhaust is more readily achievable and� permitting
will b�e��less complex.
5. Pyrolysis of biosolids results in the destruction of PFAS; which are an emerging
concerning contaminant that could affect land applica�ion of biosolids in th��future�.
Report to Redding City Council September29, 2020
Re: 4.11(h)--Authorize Biosolids Pyrolysis Project at CCWiNTP Page 3
6. Pyrolysis is largely unaffected by the nitrogen content of the�biosolids being process�ed;
which makes this� technology particularly attractive when taking into consideration the
acceptance of food�waste.
7_ Pyrolysis can be a self-sustained process that generates enough energy such that
�electricity �or natural gas are not used once �stable �operation is achieved, �once the
pyrolysis process operating temperature is reached (using syngas generated from the
biosolids to burn).
The Biosolids Master Plan recammended that t�ie City consider implementing a "small-scale
pyrolysis system at Clear Creek Wastewater Treatment Plant (CCWTP) in order to gain
�operating experience� to prove the �technology prior to constructing �a full-scale facility� As of
�today; pyrolysis is an e������ technology and selection of this alternative may result in the
need to sole-source ���,�t��;������{'�tt��quipment provider with a track record of proven municipal
installations, giv���������'e are very` �t ,,m the United States. Operation of a small-scale facility
could be an im�����t step in meetin�'�'��ulatory goals and establishing a permanent solution for�

The BFT-BioDryer can save up to 70°io in energy costs cor���������`conventional belt or paddle dryer
L�.
since it uses the metabolic energy of bacteria that naturally occur in biosolids, instead of costlyfossil
fuels. Each BFT-BioDryer unit is able to dry 8 wet tons of biosolids at20°io TS in as quick as 60 hours.
The result is Class A biosolids at 75-90°io TS;The BFT-Biodryer is a modular configuration allowing
units to be added to increase capacity and production af rich organic material.

BFT Pyrolysis Units
"Pyrolysis" is the thermochemical decomposition of organic material through the
application ofi heat without the addition of extra oxygen. Through pyrolysis
Bioforectech is able to recuperate value from biosolids,transforming it into
renewable energy and OurCarbon0 biochar. Biochar is a carbon based producfthat is no longer
considered a biosolid. Biochar produced from the BFT-Pyrolysis has economic value and can be sold
as a fertilizer or as a material that can be used to makesustainable products
(htt s: wvuw.r��d�vvithcat�rc�rbc�r�.�e�r�).

The BioForceTech (BFT) plant was designed and built to combine a low energy consumption drying
process(mediated by bacterial activity),with a system to add value to biosolids (through a pyrolysis
process), in order to obtain a plant having a positive energy balance.

"Upcycling,also known as creative reuse, is the process of transforming by-products,waste
materials, useless, or unwanted products into new materials or products of better quality or for
better environmental value."
At Bioforcetech we embrace this concept and realize it with our sustainable system,converting organic waste
into renewable energy and biochar.
Biochar is charcoal used as a soil amendment. Biochar is a stable sofid-rich in carbon,and can endure in soil
forihousands of years. B�och��,���'����i�`��;k�e pote�ntialto help mitigate climate�change�via�carbon

�These metabt�lic reactions alone can significantly�incre������h��� t����i'�ture inside the reactor in a�few�

a correct air flow,are used as the means to carry and evaporate the water held by the material,thus
leading to a high dry solids concentration.

Equipment:
The BioDryer is composed of an external structure that is made with painted steel ta
prevent rust corrosion and strength loss, and internal parts that are made of AISI
304L and AISI 304 stainless steel.
The AISI 304L is used when a welding process is needed.The stainless steel prevents fast
deterioration.The reactor looks like an octagonal rotating drum and ismoved by a motor reducer and
linked to an aeration system. Loading and unloading gates are present on one side of the octagon.
The air system is composed of two blowers,polypropylene (PPH) pipes,and one heat exchanger.The
�first centrifugal fan bl����}�������t��side the reactor and provides oxygen for the process. The second
�blower sucks the�������#����'��t���'���,;,�team formed during the process.
The PPH guara������`esistance to �����'�ssive chemical agents and also has a good resistance to high
�temperature����'�i�230°F. f �

Background/Anulysis
The City of Redding (City) owns and operates two municipal wastewater treatment plants
{WWTPs): The C1ear Creek p�ant (CCWWTP) generally serves the west side ofRedding with a
tributary area population of apprc�ximately '74,000 people. The Stillwater plant (SWWTP)
generally serves the east side of Redding with a tributary area population of approximately
24,000 people. Both plants discharge directly treated water to�he Sacramento River.
Prior to 2014; the City disposed of WWTP biosolids through a combination ofland application at
the Redding Airport and landfilling. However; the lar�d application site is nearing its lifetirne
�capacity to accept additional biosolids due to metals loading, and� the �+City has nnw been
��exclusively�disposing of b�����11ds at the West Central LandfilL This change also coincided with

Re: 4.11(d)--Award RFP No. 5279 Consulting Cantract Page 3
�Two proposals were�received on November 20, 2020, from Water Works Engineers and GHD,
Consultants, both of Redding. Copies were distributed to the selection panel made up of Public
Works and Treatment P1ant staff and evaluated on the following factors — understanding of the
scope of work,abilityto�meet the proposed schedule and maintairi the�project budget, experi�nce
�and qualifications of the proposed staff, project approach, f�miliarity with City projects;
requirements and standards, and geographic location of the teain. Applying these criteria to the
proposals, the selection panel determined that Water VVorks Engineers is the best candidate to�
provide the required services for this proj�ect.
If authorized, staff will negotiate a final cost based on the scope of required services with Water

pyrolysis� unit to bett�r prepare the City� �of Redding (City) to comply with environmental
regulations and provide a long-term sustainable solution to the disposal of biosolids from both
wastewater treatment plants. The handling and�disposal of biosolids is highly regulated, with
�eontinuously evolving environmental legislation in the State��of California. The�City of Redding
(City) currently disposes of this�material at the local]andfills.

�California Senate Bill (SB) 1383� codified California's commitments� to� reduce greenhouse� gas
�emissions and air pollution statewide. It identified methane emissions�from landfills as one area
�to address in order to meet California's target to r�duce Green House��Gas emissions 40 percent
�below 1990 levels by 2030. SB 1�383� enhances California's efforts to achieve the stiatewide 75
percent recqcling� goal by 2020, established in�California Assembly Bill�� (AB) 341, and
strengthen the implementation of mandatory commercial organics recycling establis�ed in AB
1826. As AB 341 set the roadmap to find� beneficial uses for organics and divert them from
landfills, AB 1594 specifically phases out the credit allowed from biosolids being utilized� as�
�"Alternative D��i1y�Cover" for landfills and classifies �all green waste as regul�r��disposaL Wh�t�
this means is landfills are being forced to divert arganic waste; including biosolids, whereas
landfill disposal of biosolids�wi11 not be�a viable option in the futur�.

3. Biochar has the potential to be used as � soil amendment or replacement for carbbn black

5. Pyrolysis of biosolids results in the destruction of PFAS, which are an emerging
concerning contaminant that could affect land application ofbiosolids in the future.

6. Pyrolysis� is largely unaffected by�the nitrogen content of�the�biosolids bei�g processed,
which makes this technology particularly attractive when taking into consideration the
�acceptance of food waste.
7. Pyrolysis can be a self-sustained process that generates enough energy such that
�electricitq� �or �atural� gas�� are not used once stable �operation is achieved, �once�� the�
pyrolysis process operating temperature is reached {using syngas generated from the
biosolids to burn).
The Biosolids Master Plan recommended that the City consider implementing a small-scale
�p�rt�lysis system at Clear Creek Wastewater� Treatment Plant ��(CCWTP)� in �order to gain
operating experience to prove the technology prior to constructing a full-scale facility. As of

The City of Redding (City) owns and operates tw� �z����r��ipa1 wastewater treatment plants
�(WWTPs). The Clear �Creek plant (CCWWTP)� generally �serves West Redding with a tributary�
�area population of approximately 74,000 people. The Stillwater plant (SWWTP) generally serves
�East Redding with a tributary �area population of appro�zimately 24,000 people. Both plants
�discharge�direc�ly�to�the S�acramento� River�fo�llowing treatment.
A byproduct of wastewater treatment is the accumulation of organic waste known as biosolids.
Prior to �01�4, the��City disposed of�WWTP biosolids�through a combination of land�application at
�the Redding Airport�and hauling to the�landfill. However, the land application site�is nearing its
lifetime capacity to accept additional biosolids due to metals loading, and the�City has now been
�exclusively disposing of biosolids at�the West�Cen�ral LandfiIl. This change also��coincided�with
a transition at CCWWTP from the process of using drying beds to using mechanical dewatering
with a new facility.

Backgroun�Analysis
At its meeting on August 18; 2020, the Council accepted the Wastewater Treatment` Plant`
Biosolids Master Plan (Plan). The Plan recommended an emerging technology for the handling
and disposal of Biosolids known as Pyrolysis. In response, the Council awarded a consulting and
�professional services agreement in October 2020 with Water Works Engineers (WWE) to�begin
the preliminary design process for the Clear Creek Waste Water Treatment Plant (C�WWTP)
Biosolids Drying and Pyrolysis� pilot project. As part of the preliminary design process; �a�
Request for Proposals �(RFP) was developed to solicit r�ultiple �manufacturers of the pyrolysis
�equipment to provide an equivalent element evaluation of their�ability to provide the r�quired
process for both pilot scale and ultimate build out systems.

Project cost �components� are estimates� and �some shifting of the project development and
construction contingency funds may be necessary to balance tbe project within the approved
budget.
AZter�native Action
The City Council may choose to not award the bid for the Clear Creek Wastewater Treatment
Plant Pyrolysis Phase 1 Project and provide staff with altern�tive direction. Without this�project,
staff wauld need to purs�e other alternatives to managing biosolids disposal at the treatment
plant. This may present�regulatory, technical, and financial impacts�to�the Wastewater Utility in
the near future.
