  • Guidelines for the Design and Construction Of
    Guidelines for the Design and Construction of Stormwater Management Systems Developed by the New York City Department of Environmental Protection in consultation with the New York City Department of Buildings July 2012 Michael R. Bloomberg, Mayor Carter H. Strickland, Jr., Commissioner Cover: An extensive green roof system installed atop the NYC Department of Parks and Recreation’s (DPR) Five Borough Building on Randall’s Island. This modular system is one of six variations installed on the roof and covers 800 square feet, con- sisting of two-foot by two-foot trays with six inches of mineral soil and over 1,500 sedum plugs. DPR has installed 25 green roof systems covering over 29,000 square feet on the Five Borough Building rooftop to feature different types and depths of growing medium and plant selection. Dear Friends; The NYC Green Infrastructure Plan, released in September 2010, proposed an innovative ap- proach for cost-effective and sustainable stormwater management. A major part of this plan is our commitment to manage the equivalent of an inch of rainfall on ten percent of the impervious areas in combined sewer watersheds by 2030. To that end, DEP is prepared to spend $1.5 bil- lion to construct green infrastructure projects across the city. Yet public investment alone will not achieve our water quality goals, or our desired recreation and development opportunities. Some of the most cost-effective opportunities are represented by new construction and devel- opment, when stormwater source controls can be easily included in designs and built at a frac- tion of the cost of retrofitting existing buildings.

Specifically, for the first time, rPET water bottle flake is processed using only an open source toolchain with Fused Particle Fabrication (FPF) or Fused Granular Fabrication (FGF) processing rather than first converting it to filament. In this study, first the impact of granulation, sifting, and heating (and their sequential combination) is quantified on the shape and size distribution of the rPET flakes. Then 3D printing tests were performed on the rPET flake with two different feed systems: an external feeder and feed tube augmented with a motorized auger screw, and an extruder-mounted hopper that enables direct 3D printing.

  • Damping Package Design Using Structural Corrugated Board
    RESEARCH ARTICLE Damping Package Design Using Structural Corrugated Board PREFACE API 2015 Qi Zhang Katsuhiko Saito Kobe University Kobe University [email protected] [email protected] Katsushige Nagaoka TSK Coporation [email protected] ABSTRACT Packaging is designed to protect products from shock and vibration during transport. In recent years, paper cushioning materials, such as corrugated board and pulp molded packaging, are being increasingly used because they are environmentally friendly and easy to recycle. However, because no efficient packaging-design method yet exists for paper cushioning material, packaging engineers must rely on previous experience and the so-called trial-and-error method to design packaging. One reason for this situation is that, for most cases, the paper cushioning material used for protective packaging has a complicated structure and deforms after being subjected to repetitive shock and vibration. To address this shortcoming, we propose a damping design method for corrugated-board packaging that includes shock-absorbing and vibration damping elements. To verify that the resultant packaging functions as intended, we test three types of packaging in the following way: First, we use an existing design method to create cushioned packages and examine them via free-fall drop tests. Next, to test the robustness of packaging against vibration (i.e., for packaging destined for various modes of transport), we study the three packaging types by subjecting them to (i) vibration-only tests and (ii) drop-plus-vibration tests. For vibration-only tests, the packaging with highest static stress gives the best result, its “vibration fatigue” accounts for approximately 52% of the worst result given by packaging with the lowest static stress.

  • The HP Molded Fiber Advanced Tooling Solution White Paper | the HP Molded Fiber Advanced Tooling Solution
    White paper The HP Molded Fiber Advanced Tooling Solution White paper | The HP Molded Fiber Advanced Tooling Solution Macrotrends driving the packaging market The packaging market is transitioning from foam/plastic to molded fiber (also known as molded pulp) packaging for sustainability reasons, with environmental packaging (i.e., replacing foam with paper) favoring the growth of this segment. The molded fiber packaging market is a worldwide industry, valued at $8 billion, and is the fastest-growing segment in the packaging market, with growth being fueled by growing consumer demand for sustainable and environmentally friendly packaging solutions, as well as the increase in take-out food and e-commerce.1 Asia-Pacific countries (APAC) are the biggest geographical market, especially China, Hong Kong, and Taiwan. The region is experiencing the highest growth and is expected to be the largest market by 2024. This growth can be attributed to the rising importance of disposable packaging,2 as well as the lower cost of tooling production in these areas, which presents a significant price advantage over other regions. The primary segments currently are food and beverage and electronics, which are estimated to have the highest growth. The increasing use of molded pulp products for the packaging of various electronic products (including mobile phones and accessories, computers, printers, modems, trimmers, and projectors, among others) due to its convenience, improved sustainability, and low cost are some of the factors contributing to the growth of this segment.2 Molded fiber manufacturing The thermoformed tooling segment is expected to outgrow other segments, propelled by increased consumer demand for high-quality molded fiber packaging and ongoing innovation driving down thermoforming-packaging manufacturing costs.
