[0124] Furthermore, there is no intention to be bound by any expressed or implied theory presented in the preceding technical field, background, brief summary or the following detailed description. It is also to be understood that the specific devices illustrated in the attached drawings, and described in the following specification, are simply exemplary embodiments of the inventive concepts defined in the appended claim. Hence, specific dimensions and other physical characteristics relating to the embodiments disclosed herein are not to be considered as limiting, unless the claims expressly state otherwise.

[0125] Liquefied Natural Gas (LNG) of fossil origin is a fuel that considerably reduces emissions from heavy vehicles. Biogas (including renewable Liquefied Natural Gas, which is sourced from) since it starts from the methane collection base that would go to the Atmosphere (the which is 23 times more polluting than CO2) to later convert it into combustion into CO2, it is considered a negative emissions fuel.

[0126] Liquefied Natural Gas (LNG) is sourced from fossil decomposition over millions of years and is therefore not considered to be a renewable energy source. Renewable Natural Gas (RNG), or biogas, is produced through three main processes: [0127] 1) Anaerobic digestion of organic (normally moist) material, otherwise known as biomethanation. [0128] 2) Production through the Sabatier reaction. With the Sabatier reaction, the gas from primary production has to be upgraded with a secondary step in order to produce gas that is suitable for injection into the gas grid. [0129] 3) Thermal gasification of organic (normally dry) material.

[0130] Renewable Natural Gas (RNG) is limited by cost and availability. Renewable Natural Gas (RNG) is produced from sewage, food waste such as food thrown away by supermarkets and restaurants, organic waste created by businesses such as breweries, agricultural waste, and the like. By formulating a fuel comprising a first portion sourced from fossil decomposition and a second portion sourced from a renewable source, the fuel provides an optimal solution for cost, environmental resources, and climate management.

[0131] An emission intensity, also referred to as a carbon intensity (C.I.) is an emission rate of a given pollutant relative to the intensity of a specific activity, or an industrial production process. The emission intensity can be measured as the grams of carbon dioxide (CO2) released per megajoule of energy produced. The emission intensities or carbon intensities are used to derive estimates of air pollutant or greenhouse gas emissions based on the amount of fuel combusted, the number of animals in animal husbandry, on industrial production levels, distances traveled or similar activity data. Emission intensities may also be used to compare the environmental impact of different fuels or activities.

[0132] Renewable Natural Gas (RNG) can be created and collected from a variety of different sources. Each of the different biomass sources generates a Renewable Natural Gas (RNG) having a different carbon intensity level. For example, the volume of the fossil generated Liquefied Natural Gas (LNG) is higher in (a) a mixture where the fuel composition includes a Renewable Natural Gas (RNG) produced from cow dung generating a carbon intensity of 200 grams of carbon dioxide released per megajoule of energy compared to (b) a mixture where the fuel composition includes a Renewable Natural Gas (RNG) produced from wastewater generating a carbon intensity of 40 grams of carbon dioxide released per megajoule of energy. A liquefied fuel composition comprising a first volume comprising fossil generated Liquefied Natural Gas (LNG) 24 and a second volume comprising biomass generated renewable Natural Gas (RNG) 22 is introduced in a liquefied fuel composition chart 10 presented in FIG. 1. The liquefied fuel composition chart 10 presents a percent contribution 14 of each of the biomass generated renewable natural gas (RNG) 22 and the fossil generated Liquefied Natural Gas (LNG) 24 of a total fuel composition 20 based upon a carbon intensity level 12 of the biomass generated renewable natural gas (RNG) 22. As the Carbon Intensity level increases, the contribution of the biomass generated renewable natural gas (RNG) 22 also increases to maintain a total fuel composition 20 which generates a zero sum mixture of carbon intensity.

[0133] As illustrated, a volume of the fossil generated Liquefied Natural Gas (LNG) 24 is higher in (a) a mixture where the fuel composition 20 includes a Renewable Natural Gas (RNG) 22 produced from a source generating a carbon intensity 12 of a lower units of mass of carbon dioxide released per unit of energy compared to (b) a mixture where the fuel composition 20 includes a Renewable Natural Gas (RNG) 22 produced from a source generating a carbon intensity 12 of a higher units of mass of carbon dioxide released per unit of energy.

[0134] For example, the volume of the fossil generated Liquefied Natural Gas (LNG) 24 is higher in (a) a mixture where the fuel composition 20 includes a Renewable Natural Gas (RNG) 22 produced from cow dung generating a carbon intensity 12 of 200 grams of carbon dioxide released per megajoule of energy compared to (b) a mixture where the fuel composition 20 includes a Renewable Natural Gas (RNG) 22 produced from wastewater generating a carbon intensity 12 of 40 grams of carbon dioxide released per megajoule of energy.

[0135] Similarly, a volume of the fossil generated Liquefied Natural Gas (LNG) 24 is lower in (a) a mixture where the fuel composition includes a Renewable Natural Gas (RNG) produced from a source generating a carbon intensity of a higher units of mass of carbon dioxide released per unit of energy compared to (b) a mixture where the fuel composition includes a Renewable Natural Gas (RNG) produced from a source generating a carbon intensity of a lower units of mass of carbon dioxide released per unit of energy.

[0136] For example, the volume of the fossil generated Liquefied Natural Gas (LNG) 24 is lower in (a) a mixture where the fuel composition 20 includes a Renewable Natural Gas (RNG) 22 produced from wastewater generating a carbon intensity 12 of 40 grams of carbon dioxide released per megajoule of energy compared to (b) a mixture where the fuel composition 20 includes a Renewable Natural Gas (RNG) 22 produced from cow dung generating a carbon intensity 12 of 200 grams of carbon dioxide released per megajoule of energy.

[0137] The Renewable Natural Gas (RNG) 22 can comprise one of a first portion obtained from a first biomethane source having a first carbon intensity 12 and a second portion obtained from a second biomethane source having a second carbon intensity 12, wherein the mixture has a total carbon intensity 12 based upon the sum of the carbon intensity 12 of the first portion of the Renewable Natural Gas (RNG) 22 and the carbon intensity 12 of the second portion of the Renewable Natural Gas (RNG) 22 used in the fuel composition to generate the zero sum mixture of carbon intensity.

[0138] A fuel emissions table 100, presented in FIG. 2, illustrates the environmental and economic statuses of the following fuel types 102: conventional Liquefied Natural Gas (LNG) 110, dairy sourced bio liquefied natural gas 112, and gasoline 114. The environmental levels associated with use of the various fuel types 102 is presented in a column presenting an emissions (GR CO2/MJ) 104 resulting from use of the respective fuel type 102. In this column, the use of the conventional Liquefied Natural Gas (LNG) 110 as a fuel exhausts an estimated conventional Liquefied Natural Gas (LNG) emissions 120 of 88.01 GR CO2/MJ, the use of the dairy sourced bio liquefied natural gas 112 as a fuel exhausts an estimated dairy sourced bio liquefied natural gas emissions 122 of −283.27 GR CO2/MJ, and the use of the gasoline 114 as a fuel exhausts an estimated gasoline emissions 124 of 100.45 GR CO2/MJ.

[0139] The economics associated with use of the various fuel types 102 is presented in a column presenting a US dollars/one million British Thermal Units (USD/MMBTU) 106 of the respective fuel type 102. In this column, the conventional Liquefied Natural Gas (LNG) 110 has an estimated cost efficiency rate 130 of 8 USD/MMBTU, the dairy sourced bio liquefied natural gas 112 has an estimated cost efficiency rate 132 of 40 USD/MMBTU, and the gasoline 114 has an estimated cost efficiency rate 134 of 18 USD/MMBTU.

[0140] The use of a fuel having a bio ratio 116 of 23.7% (biogas to liquefied natural gas ratio (Bio Ratio 126)) reduces the emission rate from 88.01 GR CO2/MJ (120) associated with conventional Liquefied Natural Gas (LNG) to 0.01664 GR CO2/MJ (128), while increasing the economic impact from 8 USD/MMBTU (130) to 15.584 USD/MMBTU (138). The bio ratio liquefied natural gas (Bio Ratio) 116 having a suitable mixture can be referred to as a zero emission Liquefied Natural Gas (LNG) 118. The use of the zero emission Liquefied Natural Gas (LNG) 118 as a fuel exhausts an estimated zero emission Liquefied Natural Gas (LNG) emissions 128 of 0.01664 GR CO2/MJ. The zero emission Liquefied Natural Gas (LNG) 118 has an estimated cost efficiency rate 138 of 15.584 USD/MMBTU.

[0141] The convention Liquefied Natural Gas (LNG) 110 can be a conventional Natural Gas, where the conventional Natural Gas is selected from one of (a) conventional Liquefied Natural Gas (LNG) or (b) conventional Compressed Natural Gas (CNG). In a composition where the conventional Natural Gas is a conventional Compressed Natural Gas (CNG), the resulting zero emission composition would be a zero emission Compressed Natural Gas (CNG) 118.

[0142] The fuel having a bio ratio liquefied natural gas (Bio Ratio) 116 is considered as being a target or optimal ratio. The ratio between the renewable liquefied gas (RNG) 152 and the fossil sourced Liquefied Natural Gas (LNG) 154 can vary based upon any of a number of factors. A biomix Liquefied Natural Gas (LNG) composition by percentage of total volume 150, presented in FIG. 3A, defines a fuel composition based upon a percentage of a Renewable Natural Gas (RNG) 152 of the total volume of the fuel. A balance of the fuel composition would include a percentage of the fossil sourced Liquefied Natural Gas (LNG) 154 and other ingredients or additives, such as a cleansing solution, a moisture absorbent, a combustion additive, and the like.

[0143] The biomix Liquefied Natural Gas (LNG) composition by percentage of total volume 150 identifies a number of ranges of the Renewable Natural Gas (RNG) 152 to manufacture the fuel composition. A target or optimal fuel composition, the Renewable Natural Gas (RNG) would by 19.2% of the overall volume of the fuel composition. The balance of 80.8% of the total volume of the fuel composition would include a volume of fossil sourced Liquefied Natural Gas (LNG) and any additives.

[0144] A most optimal fuel composition, the Renewable Natural Gas (RNG) would comprise between 19.0% and 19.5% of the overall volume of the fuel composition. The balance of between 81.0% and 80.5% of the total volume of the fuel composition would include a volume of fossil sourced Liquefied Natural Gas (LNG) and any additives.

[0145] A more optimal fuel composition, the Renewable Natural Gas (RNG) would comprise between 18.5% and 19.5% of the overall volume of the fuel composition. The balance of between 81.5% and 80.5% of the total volume of the fuel composition would include a volume of fossil sourced Liquefied Natural Gas (LNG) and any additives.

[0146] A less optimal fuel composition, the Renewable Natural Gas (RNG) would comprise between 18.5% and 20.0% of the overall volume of the fuel composition. The balance of between 81.5% and 80.0% of the total volume of the fuel composition would include a volume of fossil sourced Liquefied Natural Gas (LNG) and any additives.

[0147] A least optimal fuel composition, the Renewable Natural Gas (RNG) would comprise between 18.0% and 20.0% of the overall volume of the fuel composition. The balance of between 82.0% and 80.0% of the total volume of the fuel composition would include a volume of fossil sourced Liquefied Natural Gas (LNG) and any additives.

[0148] A most general fuel composition, the Renewable Natural Gas (RNG) would comprise between 16.0% and 22.0% of the overall volume of the fuel composition. The balance of between 84.0% and 78.0% of the total volume of the fuel composition would include a volume of fossil sourced Liquefied Natural Gas (LNG) and any additives.

[0149] A more general fuel composition, the Renewable Natural Gas (RNG) would comprise between 15.0% and 25.0% of the overall volume of the fuel composition. The balance of between 85.0% and 75.0% of the total volume of the fuel composition would include a volume of fossil sourced Liquefied Natural Gas (LNG) and any additives.

[0150] A general fuel composition, the Renewable Natural Gas (RNG) would comprise between 15.0% and 30.0% of the overall volume of the fuel composition. The balance of between 85.0% and 70.0% of the total volume of the fuel composition would include a volume of fossil sourced Liquefied Natural Gas (LNG) and any additives.

[0151] Each of the above ranges can be considered to be inclusive or exclusive of the range boundaries.

[0152] Although the details presented above refer to a fossil sourced Liquefied Natural Gas (LNG) 154, the fossil sourced Liquefied Natural Gas (LNG) 154 can be a fossil sourced Natural Gas, where the fossil sourced Natural Gas is selected from one of (a) a fossil sourced Liquefied Natural Gas (LNG) or (b) a fossil sourced Compressed Natural Gas (CNG).

[0153] A biomix Natural Gas composition by a Renewable Natural Gas (RNG) ratio 160, presented in FIG. 3B, defines a fuel composition based upon a ratio between a volume of the Renewable Natural Gas (RNG) 162 and a volume of the fossil sourced Natural Gas 164. This provides a method of determining ingredients based upon the combustible elements of the fuel composition. The balance of the total volume of the fuel composition would include any additives. The fossil sourced Natural Gas 154, the fossil sourced Natural Gas 154 is selected from one of (a) a fossil sourced Liquefied Natural Gas (LNG) or (b) a fossil sourced Compressed Natural Gas (CNG).

[0154] The biomix Liquefied Natural Gas (LNG) composition by a Renewable Natural Gas (RNG) ratio 160 identifies a number of ratios between the volume of the Renewable Natural Gas (RNG) 162 and a volume of the fossil sourced Natural Gas (LNG) 164 to manufacture the fuel composition. In a target or optimal fuel composition, a volume of the Renewable Natural Gas (RNG) 162 would be provided as a ratio of 23.7% to the volume of fossil sourced Natural Gas (LNG) 164.

[0155] In a most optimal fuel composition, a volume of the Renewable Natural Gas (RNG) 162 would be provided as a ratio of between 23.5% and 23.9% to the volume of fossil sourced Natural Gas (LNG) 164.

[0156] In a more optimal fuel composition, a volume of the Renewable Natural Gas (RNG) 162 would be provided as a ratio of between 23.2% and 24.2% to the volume of fossil sourced Natural Gas (LNG) 164.

[0157] In a less optimal fuel composition, a volume of the Renewable Natural Gas (RNG) 162 would be provided as a ratio of between 22.7% and 24.7% to the volume of fossil sourced Natural Gas (LNG) 164.

[0158] In a least optimal fuel composition, a volume of the Renewable Natural Gas (RNG) 162 would be provided as a ratio of between 21.0% and 26.0% to the volume of fossil sourced Natural Gas (LNG) 164.

[0159] In a most general fuel composition, a volume of the Renewable Natural Gas (RNG) 162 would be provided as a ratio of between 19.0% and 28.0% to the volume of fossil sourced Natural Gas (LNG) 164.

[0160] In a most general fuel composition, a volume of the Renewable Natural Gas (RNG) 162 would be provided as a ratio of between 19.0% and 28.0% to the volume of fossil sourced Natural Gas (LNG) 164.

[0161] In a more general fuel composition, a volume of the Renewable Natural Gas (RNG) 162 would be provided as a ratio of between 17.0% and 30.0% to the volume of fossil sourced Natural Gas (LNG) 164.

[0162] In a less general fuel composition, a volume of the Renewable Natural Gas (RNG) 162 would be provided as a ratio of between 15.0% and 35.0% to the volume of fossil sourced Natural Gas (LNG) 164.

[0163] Each of the above ranges can be considered to be inclusive or exclusive of the range boundaries.

[0164] The above exemplary fuel compositions reference any Renewable Natural Gas (RNG). The preferred Renewable Natural Gas (RNG) would be a Renewable Natural Gas (RNG) sourced from dairy products.

[0165] A carbon intensity of key transportation fuels is presented in a transportation fuel carbon intensity chart 200, shown in FIG. 4. The transportation fuel carbon intensity chart 200 presents the discharged emissions measured in a greenhouse gas emission rate (CO2/MU) 202 for a variety of transportation fuels 204.

[0175] The use of the dairy sourced renewable natural gas (RNG) 226 provides a significantly negative value of greenhouse gas emission rate (CO2/MU) 202. When the dairy sourced renewable natural gas (RNG) 226 is combined with the natural gas 212, the resulting fuel composition provides a fuel solution that accommodates both economic and environmental goals.

[0176] The environmental impact of various fuels is presented in several graphical representations presented in an exemplary carbon offset via renewable natural gas (RNG) study 300, shown in FIG. 5. Emissions in grams of CO2 per mega joule (gCO2/MJ) is presented in a bar graph format. The emissions are presented for three (3) distinct fuel categories: fossil fuels 310, electric vehicle power source 320, and renewable natural gas (RNG) 330. The use of electric powered vehicles (EV) 320 can be categorized as being emission reducing 302. The use of Renewable Natural Gas (RNG) can be categorized as providing an emission offset 304.

[0177] Exemplary fuels categorized under fossil fuels 310 include gasoline 312, diesel 314 and natural gas 316.

[0181] When considering the overall environmental impact of providing an energy source, including sourcing and combustion, the wastewater 334 generates an estimated emissions rate of 19 gCO2/MJ.

[0183] When considering the overall environmental impact of providing an energy source, including sourcing and combustion, the dairy 338 absorbs an estimated emissions rate of 229 gCO2/MJ (alternatively referred to as generating an estimated emissions rate of −299 gCO2/MJ).

[0184] The exemplary carbon offset via renewable natural gas (RNG) study 300 presents use of varying degrees of different fuels to obtain a carbon neutral fleet of vehicles. A exemplary logistics solutions to meet a carbon neutral footprint 340 presents two exemplary pie charts using dairy sourced Renewable Natural Gas (RNG) as a base and different power sources to obtain a carbon neutral footprint by 2030. An exemplary dairy sourced renewable natural gas/diesel logistics solution 342 presents a scenario having a continued use of diesel fuel. In this exemplary scenario, the combination requires a usage rate of 24% of the consumed fuel being dairy sourced Renewable Natural Gas (RNG) and the reduction of diesel fuel to a usage rate of 76%.

[0185] An exemplary dairy sourced renewable natural gas/electric vehicle logistics solution 344 presents a scenario converting a portion of the fleet to electric vehicles and the balance using vehicles powered by dairy sourced Renewable Natural Gas (RNG). In this second exemplary scenario, the combination requires a usage rate of 13% of the consumed fuel being dairy sourced Renewable Natural Gas (RNG) and the remaining portion of the fleet using electric powered vehicles at a usage rate of 87% to achieve the same results.

[0186] Another method considering different paths to a carbon neutral footprint based upon a carbon output from 1975 is presented in a bar chart. A exemplary carbon offset via renewable natural gas (RNG) study 350 graphically presents the impact of increasing a percent utilization of dairy sourced Renewable Natural Gas (RNG) 352. When the use of dairy sourced Renewable Natural Gas (RNG) is 30% of fuel used by the total fleet, carbon offset is estimated be reached in 2058.

[0187] The emissions from a power source are only one contributor to carbon emissions over the life cycle of the fuel composition. A renewable natural gas (RNG) vs. electric vehicle study 400 illustrates an impact on emissions of a power source over a life cycle of the power source when the power source is utilized by a transportation vehicle. The renewable natural gas (RNG) vs. electric vehicle study 400 additionally compares emissions between Renewable Natural Gas (RNG) and traditional electric vehicles (EVs). The renewable natural gas (RNG) vs. electric vehicle study 400 is based upon a number of assumptions 410. The assumptions 410 includes: [0188] 1) A vehicle size assumption 412, where the vehicle size assumption 412 is a mid-sized sedan [0189] 2) A battery production assumption 414, where the battery production assumption 414 considers battery production emissions of 50% of the total electric vehicle production emissions. [0190] 3) A electric vehicle (EV) battery life assumption 416, where the electric vehicle (EV) battery life assumption 416 considers a battery life of the electric vehicle of 112,000 miles. [0191] 4) A renewable natural gas (RNG) feedstock assumption 418, where the renewable natural gas (RNG) feedstock assumption 418 considers a flat Renewable Natural Gas (RNG) contribution over the lifetime of the vehicle. [0192] 5) A renewable natural gas (RNG) composition assumption 419, where the renewable natural gas (RNG) composition assumption 419 considers a Renewable Natural Gas (RNG) composition comprising 30% dairy sourced Renewable Natural Gas (RNG) and 70% landfill sourced Renewable Natural Gas (RNG).

[0193] An exemplary impact of each phase of a lifecycle of a vehicle is presented in an exemplary vehicle lifecycle emissions 420, shown in FIG. 6. Each phase is identified in a column identified as a life cycle stage 421. The four stages of the lifecycle 421 are: a well to tank life cycle stage 422, a vehicle production life cycle stage 424, a tank to wheel life cycle stage 426, and a end of life, life cycle stage 428. The lifecycles are presented for two (2) categories: Internal Combustion Engines (ICE), including both gasoline and Renewable Natural Gas (RNG).

[0194] The emissions associated with each segment of lifecycles for each of: Internal Combustion Engines (ICE), including both gasoline and Renewable Natural Gas (RNG) (emissions being presented in the life cycle stage for internal combustion engine (ICE) percent emissions 421A) and electric vehicles (EV) (emissions being presented in the life cycle stage for electric vehicle (EV) percent emissions 421B). The only distinction between a gasoline powered internal combustion engine and a Liquefied Natural Gas (LNG) Internal Combustion Engine (ICE) is identified in a tank to wheel life cycle stage for internal combustion engine (ICE) percent emissions 426A. The distinction is illustrated in the line chart shown in emissions over miles driven chart 440 of FIG. 6.

Emissions associated with each segment of the life cycle stage 421 for an electric powered vehicle (EV) are presented within a life cycle stage for electric vehicle (EV) percent emissions 421B.

[0196] In more detail, emissions associated with a well to tank life cycle stage 422 portion of the life cycle stage 421 for a gasoline or Liquefied Natural Gas (LNG) powered Internal Combustion Engine (ICE) are identified as a well to tank life cycle stage for internal combustion engine (ICE) percent emissions 422A (10%) within the life cycle stage for internal combustion engine (ICE) percent emissions 421A. Similarly, emissions associated with a well to tank life cycle stage 422 portion of the life cycle stage 421 for the electric powered vehicle (EV) are identified as a well to tank life cycle stage for electric vehicle (EV) percent emissions 422B (45%) within the life cycle stage for electric vehicle (EV) percent emissions 421B.

Similarly, emissions associated with a tank to wheel life cycle stage 426 portion of the life cycle stage 421 for the electric powered vehicle (EV) are identified as a tank to wheel life cycle stage for electric vehicle (EV) percent emissions 426B (0%) within the life cycle stage for electric vehicle (EV) percent emissions 421B.

[0199] Emissions associated with a end of life, life cycle stage 428 portion of the life cycle stage 421 for a gasoline or Liquefied Natural Gas (LNG) powered Internal Combustion Engine (ICE) are identified as a end of life, life cycle stage for internal combustion engine (ICE) percent emissions 428A (0%) within the life cycle stage for internal combustion engine (ICE) percent emissions 421A. Similarly, emissions associated with a end of life, life cycle stage 428 portion of the life cycle stage 421 for the electric powered vehicle (EV) are identified as a end of life, life cycle stage for electric vehicle (EV) percent emissions 428B are actually reversed (−5%) within the life cycle stage for electric vehicle (EV) percent emissions 421B.

[0200] The sum of the emissions of each segment of the life cycle stage 421 is summarized in a total 429. The total of the sum of the emissions of each segment for the lifecycle of the gasoline or Renewable Natural Gas (RNG) powered Internal Combustion Engine (ICE) is presented as a total for internal combustion engine (ICE) percent emissions 429A (100%). The total of the sum of the emissions of each segment for the lifecycle of the electric powered vehicle (EV) is presented as a total for electric vehicle (EV) percent emissions 429B (100%).

[0201] Emission rates for the exemplary fuels are graphically illustrated on the emissions over miles driven chart 440. The emissions over miles driven chart 440 charts emissions (recorded along an axis charting a CO2 emissions 443) against a mileage driven (along an axis charting a driven vehicle mileage 442 (in thousands of miles)). Emissions over miles driven for the gasoline powered Internal Combustion Engine (ICE) are referenced by an internal combustion engine (ICE) vehicle data 444. Emissions over miles driven for the Renewable Natural Gas (RNG) powered Internal Combustion Engine (ICE) are referenced by a renewable natural gas (RNG) vehicle data 448. Emissions over miles driven for the electric powered vehicle (EV) are referenced by a electric vehicle (EV) data 446. The electric vehicle (EV) data 446 includes a step function at each battery exchange based upon the assumed battery life mileage (112,000 miles).

[0202] As shown in FIG. 5, a fuel composition comprising Liquefied Natural Gas (LNG) generates an emission of 89 gCO2/MJ, while a fuel composition comprising Renewable Natural Gas (RNG) processed from dairy draws an emission reduction of 299 gCO2/MJ. These can be combined into a fuel composition meeting desired optimizing for both economic standpoint and an environmental standpoint. The fuel composition can be manufactured in accordance with any of the suggested mixtures presented in FIGS. 3A and 3B above.
