Farms in New Mexico

Source: USDA 2012 Census of Agriculture

  • 24,721 farms and ranches in

NM, an 18% increase from the previous census in 2007

  • 43,200,000 acres of

farm/ranch-land in NM (67,500 square miles NM is 121,697 square miles)

  • Annual Market Value of

Agricultural products sold $2.5 billion

  • Nearly half of that is from dairy

sales

  • Approx 157 dairy farms
  • $1.22 billion in sales

Feeding NM’s Dairy Cows is Big Business

5

  • One milk-producing cow consumes 50-90

lbs of silage per day

  • 7500-13500 TONS of silage consumed in

NM per day

slide-6
SLIDE 6

Dairy Silage

  • Plastic film is used to create an anaerobic

environment to ferment silage for dairy cow feed

  • Silage sheets are 5mm thick and made of co-

extruded low density polyethylene (LDPE) with a small % of Linear LDPE (LLDPE) added for flexibility

  • Currently many farmers are burying the

material on their property or paying to take it to the landfill

Acres of Corn Silage or Greenchop Harvested as a Percent of Total Acres of Harvested Crops

7

  • 75,000 harvested acres of silage

production in NM, yields of 23-32 tons/acre = 1,725,000 tons of silage per year

  • 6.2 square feet of silage film used

per ton

  • 10.7 million square feet of

silage film used in NM annually = 350,000 lbs of film, conservative estimate

slide-8
SLIDE 8

Volume Estimate of Silage in NM

8

  • Nationally estimate 4-5 lbs of agricultural plastic film per cow per year = would

equal 1.2 million lbs of film in New Mexico

  • Difference could be how silage is “put-up” differently in each state

“Hay Wraps” in Wisconsin Bunker Cover Silage pile – used in NM

Livestock Nutritional Supplements

  • Used to provide additional nutrients to

dairy cattle, beef cattle, horses, sheep and goats during winter months (Sept – May)

  • Colored HDPE tubs
  • An average a ranch with 65 beef cows

and 4 horses uses about 50 tubs per year

  • 1.54 million cows, sheep and goats in NM

= approximately 1.1 million tubs per year in NM (not including horses)

  • Currently reused on site or sent to landfill

Pesticide and Fertilizer Concentrates

  • Currently triple rinsed and landfilled
  • HDPE plastic (primarily clear)
  • Took 1850 acre farm about 10 years

to fill the container in photo.

  • Average of 1 jug per 10 acres per

year = 4.32 million HDPE jugs in NM per year

Drip Irrigation Tubing (+OCC & Organics!)

  • Greenhouse tubbing is cleaner than field

tubbing

  • Seasonal switch outs per year (Nov/Dec

& June/July)

  • Consists of polyethylene tubes

Challenges

12

  • Dirty
  • Contaminants (tires, silage, different

films)

  • Low value plastic
  • Lack of collection efficiencies
  • Potentially toxic containers from

pesticides/fertilizers

  • Hard to consolidated
  • Labor expenses to make bales
  • Material collection

Challenges – National Sword 2017

13

  • Updated version of China’s custom

policies, Green Fence from 2013

  • Launched by China’s General

Administration of Customs (GAC)

  • Targets imported waste, including

scrap plastics and electronics.

  • The enforcement campaign is a

reflection of the Chinese government’s plan to crack down

  • n recycling operations

which don’t have the proper controls and facilities and focuses on materials causing severe pollution because of improper recycling at ill-equipped facilities.

  • The campaign is set to run for one year, however the policy may become the new

standard

Challenges – National Sword 2017

  • Custom checks on all imported

materials – quadrupling time btwn purchase and consumption of recyclable materials

  • Returned shipments to country of
  • rigin (demurrage fees, etc)
  • Officials conducting inspections of

processing factories and have reportedly suspended operations at facilities using improper water- treatment processes. Effects

  • Many forwarding agents have suspended their operations due to the action.
  • Exposed smuggling activities that have led to dozens of arrests and confiscation
  • f over 22,000 tons of material.
  • China has been able to catch criminal activity that was being disguised through

imported waste.

  • In NM 17% decrease in market price for natural HDPE from April to May of 2017

Feasibility Assessment – “Test Bale”

Bale No. Full Bale? Weight (lbs) Baled Cubic Yards 1 Yes 2,200 1.16 2 Yes 2,160 1.16 3 No 840 0.58 Totals 5,200 2.89

Volume reduction through baling is about a 10:1 ratio (i.e., approx 30 cubic yards loose was reduced to approx 2.9 cubic yards baled)

Feasibility Assessment – “Test Bale”

slide-17
SLIDE 17

17

Summary:

  • 3 bales were made from the plastic

with the Estancia Valley Solid Waste Authority’s manual horizontal bailer. Each full bale took 60 minutes to make with two staff members

  • A typical single-stream recyclable

bale takes approximately 10 minutes to make and weighs 1,200 pounds

Feasibility Assessment – “Test Bale”

  • A typical cardboard bale takes approximately 20 minutes to make and weighs

1,200 pounds

  • Estimated costs to process one 30 yard roll off container for test bale - $150 in

labor + $46 in transportation (40 miles roundtrip) = $196 for the 3 test bales = $75.38 per ton

slide-18
SLIDE 18

Feasibility Assessment – “Test Bale”

  • The plastic fed into the baler in an

acceptable manner. However, a large time saving would be realized if the plastic was rolled into approximate 3 ft diameter by 5 ft long rolls

  • Different types of plastic sheeting cannot

be economically separated at the landfill. If end-markets require plastic separation, it must be done at the source and put into separate containers.

Labor (2 staff for 3 hours) Transportation (40 miles roundtrip) Total Processing Cost Per Ton

Test Bale $ 150.00 $ 46.00 $ 196.00 $ 75.38 Better Prepared at Source $ 75.00 $ 46.00 $ 121.00 $ 46.54

Possible End-Markets – Silage Film

  • T

est bale taken to Friedman Recycling

  • Revolution Plastics (Delta Plastics)
  • Offers free agricultural and silage plastic recycling

with free on-farm collection in Minnesota, Wisconsin and California

  • NM would need to provide 3-5 million tons of plastic

per year for full service, smaller volumes for partial service

  • Possible regional partnership?
slide-21

Thousands of farmers and applicators nationwide participate in a free recycling

  • programs. The Ag Container Recycling Council is fully funded by their member

companies and affiliates that formulate, produce, package and distribute crop protection and other pesticide products.

SLIDE 26

26

  • HDPE #2 plastic, can be recycled with

most curbside and drop off recycling program in NM

  • Considerations – accommodate for

larger sized containers (bigger than a laundry detergent bottle)

  • Educate people that they can be

recycled

  • Potential for reuse – set up on site

reuse area
